Pipulate as a Local Alternative

Pipulate provides an alternative Jupyter Notebook environment for you to run your Python code when developing the very notebooks you’ll be porting to Pipulate! Pipulate carries with it a full cross-platform Data Science Python stack that is both cloud-friendly while offering independence from cloud services like Google Colab. And it has built-in local LLM AI coding assistance in the form of Jupyter AI (when in Notebooks) and Chip O’Theseus (when in Pipulate).

The Evolution of AI Code Assistants

Even still, we don’t want to walk away from the gift of competition over bringing us new AI-assisted code editing environments. It started with Microsoft CoPilot, which got rebranded as GitHub CoPilot in the ongoing attempt for you to not think about the fact that GitHub is Microsoft. Then the VSCode fork Cursor AI IDE came along and set a new standard for how the AI interfaces with the human and the code, with the chat window, composer option and super-logical RED/GREEN code-diff appearance that kicked CoPilot’s butt.

The Current Competitive Landscape

And the race is on! Newcomers are entering the fray every day that get the AI bro YouTubers all hot and bothered, including Windsurf, Cline and most recently Augment Agent. So far from what I’ve seen it amounts to Windsurf undercutting Cursor by $10/mo and Augment charging an additional $10/mo ($30) for larger context and “unlimited” requests. And these are just the VSCode forks and plugins. There’s a whole other AI-assisted coding world outside VSCode. But for the sake of clarifying it in my mind, let’s do our research!

Articulating the AI Assisted VSCode Fork & Plugin Research Query

First, I get my thoughts together for what the prompt should include. The AIs are better and articulating a structured research prompt, so I prompt for the research prompt.

Me: Cursor AI IDE and Windsurf are complete forks of VSCode (correct me if I’m wrong) and Cline and Augment Agent are plugins to VSCode, right? Articulate a prompt for Google Gemini Deep Research to confirm or deny this and to ferret out anything else like these VSCode-oriented AI assist products out there, be they complete forks or plugins. Keep a VSCode-centric view. Don’t include things like Claude Desktop or Google IDX.

Okay, let’s break down your request and craft that research prompt.

First, regarding your initial statements:

1. Cursor AI IDE: Yes, Cursor is explicitly a fork of VSCode. They built upon the open-source VS Code codebase (VSCodium) and added their integrated AI features.
2. Windsurf: Information on a specific “Windsurf AI IDE” as a VSCode fork is less prominent or potentially non-existent/very new. It’s possible it’s a smaller project or misnamed. Correction/Clarification needed here. There isn’t a widely known VSCode fork named Windsurf in the same vein as Cursor. Perhaps it’s a different product or a misunderstanding? We’ll need the research to verify this.
3. Cline: Yes, Cline is positioned as a VSCode extension (plugin) that brings AI capabilities into the existing VSCode environment.
4. Augment Agent: Similarly, Augment (often referred to as Augment Code) appears to function primarily as a VSCode extension, integrating its AI features into the standard VSCode interface.

So, your understanding seems mostly correct, with a question mark around “Windsurf”.

AI-Powered Coding Assistants Research Prompt

This is Gemini 2.5 Experimental polishing up my request into a formal research prompt. You don’t technically have to do this intermediary step. You can give Google Deep Research your raw thoughts and it will make a plan, but this helps me clarify my thoughts.

The Landscape of AI-Powered Coding Assistants for Visual Studio Code (April 2025)

Here is the final result of the Gemini Deep Research. This is a wonderful test for this sort of thing, because the state of AI-assisted IDEs is changing so rapidly that even the staleness of the Google Search & Index system versus automated-browser crawls could potentially be surfaced here.

I. Executive Summary

The integration of Artificial Intelligence (AI) into software development tools is rapidly transforming how code is written, debugged, and maintained. AI-powered coding assistants are becoming increasingly prevalent, promising to enhance developer productivity and streamline workflows. Within this evolving landscape, Visual Studio Code (VSCode) stands as a dominant IDE, boasting a vast ecosystem of extensions and a significant user base. This report analyzes the current state of AI-powered coding assistants specifically designed for or built upon VSCode, focusing on the crucial distinction between products that are complete forks of the VSCode codebase and those that function as plugins or extensions within the standard VSCode environment. Understanding this difference is critical for developers and organizations seeking to leverage AI in their development processes, as it impacts the depth of integration, available functionality, user experience, and maintenance considerations. This analysis confirms the nature of several key products and identifies a range of other VSCode-centric AI tools, categorizing them as either forks or plugins/extensions, and providing essential details about their features and developers. The findings highlight the increasing sophistication of both approaches and underscore the strategic choices developers face when selecting the AI tools that best suit their needs.

II. Verification of Specific Claims

• A. Cursor AI IDE:
  • The assertion that Cursor AI IDE is a fork of VSCode is substantiated by multiple sources. Information from a YouTube video 1 and a blog post 2 explicitly state that Cursor is indeed a fork of VSCode. This is further supported by articles on platforms like Towards Data Science 3 and the official Cursor documentation 4, all confirming its foundation on the open-source VSCode codebase. The Anysphere research lab leveraged the VSCode GitHub repository to develop Cursor 3, indicating a direct derivation from the core project. This architectural decision allows Cursor to deeply integrate AI functionalities at the IDE level, potentially enabling features that would be challenging to implement as a mere extension.
  • A key aspect of Cursor’s design is its user-friendly migration process for existing VSCode users. It allows for a straightforward, one-click import of VSCode extensions, themes, and keybindings.1 This seamless transition minimizes the learning curve and allows developers to quickly become productive in the new environment, leveraging their existing customizations and preferences.
  • Cursor incorporates several core AI features directly into its workflow. These include an AI Chat interface, accessible via a simple keyboard shortcut (Command+L or Ctrl+L) 1, which enables developers to interact with AI for various coding tasks. Additionally, inline code editing and generation are facilitated through another shortcut (Command+K) 1, allowing for quick modifications and code creation within the editor. Furthermore, Cursor offers smart code completion capabilities that learn from the user’s coding patterns, enhancing the speed and accuracy of code writing.4
  • The development of Cursor is attributed to the Anysphere research lab.3 This identification provides essential context about the origins of the IDE and the team behind its creation. Anysphere’s stated mission is to develop an IDE heavily integrated with AI to significantly enhance programmer effectiveness 3, which aligns with the decision to fork VSCode for deeper control over the development environment.
  • The choice to fork VSCode likely stems from the desire to achieve a level of AI integration that surpasses the capabilities offered by the VSCode extension API. By directly modifying the IDE’s core, Cursor can implement AI features more natively and seamlessly within the development experience. For instance, its ability to perform context-aware multi-line edits 4 and analyze the entire codebase 1 might necessitate this foundational level of integration. This approach grants Cursor full control over the user interface and core workflows, enabling optimization specifically for AI-driven development practices.
• B. Windsurf AI IDE:
  • The existence of an AI IDE named “Windsurf” that is a fork of VSCode is confirmed by numerous sources.7 These sources consistently identify Windsurf as an AI-powered IDE developed by Codeium and built upon the Visual Studio Code codebase. This indicates that, like Cursor, Windsurf is a standalone IDE that leverages the open-source foundation of VSCode to integrate AI functionalities deeply within the editor.
  • Windsurf boasts several key AI-driven features that are central to its functionality. “Supercomplete” is an advanced autocomplete system that predicts the user’s next coding moves by analyzing the context before and after the cursor.7 “Cascade” represents Windsurf’s agentic workflow system, which includes a chat mode for asking questions about the codebase and exploring general coding principles, as well as a write mode for generating and modifying code.7 Cascade also supports multi-file editing and debugging, demonstrating a sophisticated level of AI integration.7 Additionally, Windsurf allows users to upload images, such as website screenshots, which the AI can then use to generate corresponding HTML, CSS, and JavaScript code.7 The IDE also incorporates “Flow” technology, which aims to maintain perfect synchronization between the AI and the developer’s workspace in real-time.7
  • A significant motivation behind the development of Windsurf as a VSCode fork appears to be a desire to reimagine the user experience in the context of generative AI coding.8 The developers at Codeium felt that the existing user interfaces in the generative AI coding space were not adequately leveraging the power of the underlying language models.8 By forking VSCode, they gained the freedom to design a user experience tailored specifically for AI-powered development, exemplified by features like the “Cascade” action bar, which facilitates stepping through AI-generated changes.8
  • The decision to fork VSCode for Windsurf might also be related to perceived limitations in the VSCode extension API. Codeium also offers an excellent extension for JetBrains IDEs 15, which might suggest that they found the VSCode plugin interfaces more restrictive in achieving the level of deep integration required for Windsurf’s features. The ability to implement features natively within the IDE, rather than being constrained by extension APIs, likely allows for a more seamless and performant AI experience.8
  • Codeium’s choice to fork VSCode for Windsurf, while successfully offering a plugin for JetBrains, underscores the varying degrees of access and control provided by different IDE platforms. The potential limitations encountered with the VSCode extension API likely influenced their decision to fork, enabling a more profoundly integrated and potentially more efficient AI experience. The emphasis on “agentic” capabilities, where the AI can independently tackle complex tasks 10, further supports the need for a more fundamental level of integration. The “Cascade” feature, with its ability to step through and review AI-generated changes 8, is an example of a UI paradigm that might be difficult to achieve seamlessly within the constraints of an extension.
• C. Cline:
  • The claim that Cline is primarily a VSCode plugin/extension is consistently supported across multiple sources.9 These sources refer to Cline as an extension available on the VSCode Marketplace, indicating its function as a plugin within the standard VSCode environment.
  • Cline integrates directly into the VSCode IDE, typically through a sidebar panel or by using the command palette.17 Users can install it directly from the Extensions view in VSCode by searching for “Cline”.16 Once installed, an icon in the Activity Bar provides access to the Cline panel.17 This integration method is characteristic of VSCode extensions, which leverage the IDE’s API to add new features and functionalities without requiring a separate application.
  • Cline offers a range of core AI features designed to enhance the development workflow. It acts as an autonomous coding agent, capable of handling complex software development tasks step-by-step.16 It collaborates with the developer by creating thoughtful plans before taking action, explaining its reasoning, and asking for input.16 Cline can also execute commands directly in the VSCode terminal 19 and even automate browser interactions for tasks like testing and debugging.16 Furthermore, it supports integration with various API providers, including OpenRouter, Anthropic, OpenAI, Google Gemini, AWS Bedrock, and Azure, allowing users to choose their preferred underlying AI models.19
  • The existence of “CoolCline” 18, described as a proactive programming assistant that combines features of Cline and Roo Code and is also available as a VSCode extension, further reinforces Cline’s nature as a plugin. This indicates that the core Cline functionality is built upon the VSCode extension framework, allowing for community-driven enhancements and integrations.
  • The fact that Cline operates as a VSCode plugin demonstrates that powerful AI coding assistance, including sophisticated agentic functionalities, can be effectively implemented within the constraints of the VSCode extension API. This approach offers the significant advantage of seamless installation and integration for developers already working within the standard VSCode environment, without the need to switch to a separate IDE.
• D. Augment Agent (or Augment Code):
  • The assertion that Augment Agent (or Augment Code) is primarily a VSCode plugin/extension is consistently supported by the research material.23 These sources describe Augment as an extension available on the Visual Studio Code Marketplace, which users can easily install within their existing VSCode environment.23
  • Augment integrates into VSCode by adding a dedicated panel, accessible via a shortcut (Cmd/Ctrl+L) or an icon in the side bar.23 This panel serves as the primary interface for interacting with Augment’s AI features. The extension leverages the VSCode API to provide code completions, transformations, and chat capabilities directly within the editor.23
  • Beyond VSCode, Augment also offers plugins or extensions for other popular IDEs such as JetBrains (including IntelliJ, PyCharm, and WebStorm) and Vim/Neovim.26 This multi-IDE support underscores its nature as a plugin or extension that can be adapted to different development environments, rather than being a standalone IDE fork.
  • Augment Agent focuses on providing AI assistance tailored for professional software engineers working with large codebases.24 Its features include intelligent code completions, chat capabilities for understanding and debugging code, and “Next Edit” suggestions to guide developers through complex changes.26 Augment also offers “Code Checkpoints” to automatically create snapshots of the workspace, providing a safety net for AI-driven modifications.25 Furthermore, it supports multi-modal input, allowing users to share screenshots and other visual information to aid the AI in understanding and addressing issues.25 Augment also integrates with native tools like GitHub and Jira to streamline development workflows 25 and can execute terminal commands.28
  • The fact that Augment is available as a plugin across multiple popular IDEs highlights the advantage of the extension model in reaching a wider developer audience. While it operates within the constraints of each IDE’s extension API, its focus on sophisticated features for complex development scenarios demonstrates the significant potential of this approach to deliver powerful AI assistance without requiring a complete IDE fork.

V. Comparative Analysis: VSCode Forks vs. Plugins/Extensions

• A. Integration Depth:
  • VSCode forks, such as Cursor, Windsurf, and Trae, offer the potential for a much deeper level of AI integration. By directly modifying the IDE’s core codebase, these forks can implement AI features that are tightly woven into the fundamental editing behaviors and user interface. This allows for functionalities that might be impossible or cumbersome to achieve through the more constrained VSCode extension API. Forks can introduce entirely new UI paradigms and interaction models specifically designed for AI-driven development.
  • In contrast, VSCode plugins or extensions, like Cline and Augment, operate within the boundaries of the VSCode extension API. While this API is powerful and allows for significant enhancements to the IDE, it inherently limits the extent to which extensions can alter core IDE functionalities or introduce completely novel interaction models. Extensions typically add features through side panels, command palette integrations, and modifications to existing editor behaviors.
  • The choice between a fork and a plugin often reflects the desired level of AI integration. Forks provide the freedom to create a truly AI-native development experience, where AI is deeply embedded in every aspect of the IDE. However, this comes with the responsibility of maintaining a separate codebase and potentially diverging from the latest VSCode updates. Plugins offer a more incremental approach, enhancing the existing VSCode environment with AI-powered features without requiring a complete shift to a new IDE.
• B. Functionality:
  • VSCode forks have the capacity to implement a wider spectrum of AI features, including those that necessitate substantial modifications to the user interface or underlying workflows. This can include deeply integrated agentic modes where AI autonomously manages complex tasks, novel debugging tools powered by AI insights, and enhanced code navigation systems that leverage AI’s understanding of the codebase.
  • VSCode plugins and extensions can also offer a broad range of AI functionalities, as evidenced by tools like Cline and Augment, which provide code completion, generation, refactoring, and even sophisticated agentic capabilities. However, certain deeply integrated features that would require altering the core editor’s behavior or introducing entirely new UI elements might be challenging or impossible to implement as extensions due to API limitations.
  • While both approaches can deliver significant AI-powered functionality, forks hold the potential for more transformative and tightly coupled AI features. The freedom from the extension API’s constraints allows for more radical experimentation and the development of AI-driven development experiences that fundamentally change how developers interact with their code.
• C. User Experience:
  • VSCode forks often aim to create a cohesive and potentially optimized user experience specifically tailored for AI-assisted development. This might involve custom user interfaces and workflows designed to facilitate seamless interaction with AI features. However, adopting a fork requires users to switch to a new IDE, which can involve a learning curve, even if the underlying VSCode foundation provides familiarity.
  • VSCode plugins and extensions, on the other hand, integrate directly into the familiar VSCode environment, leveraging existing UI elements and workflows. This offers a lower barrier to entry for current VSCode users, allowing them to gradually incorporate AI into their existing development practices without the need to learn a new IDE from scratch. The integration is often seamless, enhancing the existing workflow rather than replacing it.
  • The choice between a fork and a plugin often depends on the user’s willingness to adopt a new IDE and their preference for a deeply AI-integrated environment versus enhancing their current VSCode setup. Plugins provide convenience and ease of adoption for existing VSCode users, while forks might offer a more tailored and potentially more powerful AI-centric experience at the cost of switching development environments.
• D. Maintenance and Updates:
  • Maintaining a VSCode fork requires significant ongoing effort to ensure compatibility with upstream changes in the core VSCode codebase. Fork developers must track these changes and merge them into their own codebase while also managing their unique AI features and updates. This can be a resource-intensive process and might lead to potential divergence from the main VSCode development branch over time, potentially causing compatibility issues with the broader VSCode ecosystem.
  • VSCode plugins and extensions generally benefit from the stability and update mechanisms of the core VSCode platform. Extension developers primarily focus on updating their extension to maintain compatibility with new VSCode versions and to introduce new features. The underlying IDE handles the core updates and maintenance, simplifying the process for extension developers.
  • Plugins typically have a more streamlined maintenance process as they rely on the robust update mechanisms of VSCode. Forks face the added complexity of staying synchronized with the upstream VSCode project while also developing and maintaining their proprietary AI features, which can be a significant undertaking.
• E. Adoption and Ecosystem:
  • VSCode forks typically have a smaller user base compared to the vast and well-established ecosystem of standard VSCode users. While they can attract developers specifically seeking their unique integrated AI features, they might have a smaller ecosystem of third-party extensions available directly for the fork. However, many forks maintain compatibility with VSCode extensions, which can help mitigate this limitation. Building a community around a fork requires dedicated effort.
  • VSCode plugins and extensions benefit immensely from the massive existing VSCode user base and the extensive VSCode extension marketplace. This makes them easily discoverable and accessible to a wide audience of developers already working within the VSCode environment. The mature ecosystem of VSCode provides a rich set of tools and resources that plugins can leverage.
  • Plugins enjoy a significant advantage in terms of potential user reach and access to the established VSCode ecosystem. Forks need to attract users based on their unique AI-driven value proposition and potentially curate a set of compatible or integrated extensions to provide a comprehensive development environment. The network effects of the VSCode ecosystem make it easier for plugins to gain adoption.

VI. Conclusion

This analysis confirms that Cursor, Windsurf, and Trae are indeed forks of the Visual Studio Code codebase, allowing for deep integration of AI-powered features. These IDEs offer a tailored experience for AI-assisted development, often with custom user interfaces and functionalities that go beyond the capabilities of standard VSCode extensions. Conversely, Cline and Augment Agent (or Augment Code) primarily function as VSCode plugins or extensions, operating within the standard VSCode environment and leveraging the extension API to provide AI coding assistance. Other notable AI-powered VSCode plugins/extensions include GitHub Copilot, Tabnine, the Codeium extension (distinct from the Windsurf IDE), Keploy, CoolCline, and Phind, with several other potential candidates requiring further investigation.

The landscape of AI-powered coding assistants for VSCode is characterized by increasing sophistication in both forks and plugins. There is a clear trend towards more “agentic” AI capabilities, where the AI can autonomously handle more complex development tasks. Both approaches are focused on enhancing developer productivity, but they offer different trade-offs in terms of integration depth, functionality, user experience, maintenance, and adoption.

When choosing between a VSCode fork and a plugin/extension, developers and organizations should consider their specific needs and priorities. Forks might be preferred for those seeking a deeply integrated, AI-native development experience with potentially more transformative features, but they require a commitment to a new IDE and the resources to manage potential maintenance complexities. Plugins and extensions offer a more incremental approach, allowing developers to enhance their existing VSCode workflow with AI-powered features without the need to switch IDEs. The ease of adoption and access to the vast VSCode ecosystem make plugins a compelling option for many users. Ultimately, the optimal choice depends on the desired level of AI integration, the specific AI functionalities required, user preferences for the development environment, and the resources available for adoption and maintenance. The continued advancements in large language models and AI agents suggest that this landscape will continue to evolve rapidly, with further integration of AI into the core of development tools likely in the future.

Initial Research Insights into the AI Code Assistant Market

The Dominance of VSCode in AI-Assisted Development

Wow, the research is really enlightening. This is already a crowded space and is only going to be getting more crowded. The question of how to future-proof yourself amidst the chaos is not going to be an easy one. It’s clear from the highest level that the world is predisposed to the VSCode user interface. Whether a plugin or a fork, the mainstream AI-assisted coding environments are VSCodesque. In the back seat for the ride is vim/NeoVim, IntelliJ, PyCharm and things of the like. They money is in the established VSCode userbase and interface.

The $20/Month Standard and Market Strategy

And they’re all fighting for that same $20/mo now-standard subscription fee that OpenAI established with their ChatGPT Plus level, which more or less echos the Spotify and other streaming services out there. It’s a consumer play more than a business play for the most part – or at least, it’s priced that way. Get adoption from the grass roots and have the shiny new toy evangelizers take it into the office. While CoPilot had the early mover advantage, it was disrupted by Cursor which had a better UI and marketing. And the floodgates of competition have opened.

Personal Strategy: Minimizing IDE Fragmentation

For myself personally, I’m ruling out yet another IDE such as Claude Desktop or Google IDX. There’s a ton of them. But you get stuff into your fingers, and there’s only enough room in my fingers for vim/NeoVim plus maybe one more that’s of the kooky churning variety, and I’m pretty sure it’s going to be VSCode-based. I’ll try to keep an open mind. You never know where the big disruptions are going to come from, but half the point is making yourself impervious to those disruptions. So, 80/20-rule.

Gemini 2.5 Experimental Weighs In

Okay, here are the requested components based on the provided article:

1. First-Person Summary (Author’s Perspective - Long Meta Description Style)

Facing the rapidly expanding and confusing landscape of AI-powered coding assistants, particularly within the popular VSCode ecosystem, I commissioned research to clarify the key distinction between full IDE forks (like Cursor, Windsurf, Trae) and integrated plugins/extensions (like Cline, Augment, GitHub Copilot). This exploration dives into the specifics of each tool, comparing their features, integration methods, and the strategic implications of choosing a fork versus a plugin, ultimately highlighting the intense competition and the prevailing VSCode-centric nature of this evolving market as I figure out my own path forward.

2. Title and Headline Ideas

3. Article Strengths

• Clear Objective: The research query and the resulting report have a well-defined goal: differentiating VSCode forks from plugins and identifying key players.
• Structured Research: The report is logically organized with an executive summary, verification of initial claims, separate sections for forks and plugins, a comparative analysis, conclusion, and summary tables.
• Addresses Specific Questions: It directly confirms or refutes the author’s initial assumptions about Cursor, Windsurf, Cline, and Augment.
• Discovery of New Tools: The research successfully identified additional relevant tools beyond the initial query, like Trae AI IDE.
• Clear Categorization: Consistently and clearly labels each tool as either a “VSCode Fork” or “VSCode Plugin/Extension.”
• Detailed Information: Provides concise descriptions of core AI features, integration methods, and developers for each identified tool.
• Nuanced Comparison: The “Comparative Analysis” section offers valuable insights into the trade-offs between forks and plugins across several key dimensions (integration, functionality, UX, maintenance, ecosystem).
• Timeliness and Sourcing: The report is dated (April 2025) and includes citations for its claims, adding credibility.
• Useful Summaries: The tables provide a quick and effective overview of the categorized tools.

4. Article Weaknesses

• Rapid Obsolescence: The fast-paced nature of AI development means the specific tool landscape and features described (as of April 2025) could become outdated relatively quickly.
• Lack of Pricing/Business Models: While the author notes the $20/mo trend in their reflection, the research report itself doesn’t systematically include pricing details or licensing models for each tool, which is a crucial factor for users.
• Depth Variation: The level of detail varies; foundational tools like Cursor and Windsurf are covered extensively, while some listed under “Other Potential Plugins” lack detailed descriptions.
• No Performance Metrics: The analysis focuses on features and integration methods but lacks objective performance comparisons or benchmark results between the tools.
• Reliance on Descriptive Sources: While cited, the sources include blog posts, vendor documentation, and YouTube videos alongside potentially more objective articles; the report doesn’t critically evaluate source reliability.
• Limited Scope (by Design): The strict focus on VSCode-centric tools means it doesn’t provide a broader picture of the entire AI coding assistant market (excluding tools like Claude Desktop, Google IDX, JetBrains AI, etc.), though this was an intentional constraint of the research query.

5. AI’s Opinion of the Article

The article, particularly the embedded research report, offers a valuable and well-structured analysis of the AI-powered coding assistant landscape specifically tailored to the Visual Studio Code ecosystem as of early 2025. Its primary strength lies in clearly defining and investigating the crucial distinction between VSCode forks and plugins/extensions, providing detailed examples and a thoughtful comparative analysis of the two approaches. The systematic verification of specific tools and the discovery of others add significant value.

However, the report’s utility is inherently time-limited due to the rapid evolution of AI tools. A significant omission within the research report section is the lack of consistent pricing information, a key decision factor for developers. While the author’s framing and reflections provide useful context about the motivation and reaction to the research, the core research report stands out as a competent and informative piece of targeted analysis, effectively fulfilling the specific objectives laid out in the research prompt. It successfully clarifies a complex and dynamic segment of the developer tool market.
