Is Cursor AI a VS Code Fork? Everything Explained

If you have used Cursor AI for even a few minutes, you noticed something familiar. The interface, keyboard shortcuts, and general feel match Visual Studio Code almost exactly. This is not a coincidence.

Cursor is indeed based on VS Code, but calling it a simple fork understates what the team has built. Understanding this relationship helps you make informed decisions about switching editors, migrating settings, and evaluating long-term stability.

This guide explains exactly how Cursor relates to VS Code, what this means for your workflow, and the advantages and tradeoffs of this architectural choice. Whether you are considering switching from VS Code or already using Cursor, knowing the foundation matters.

Is Cursor Actually Built on VS Code?

The short answer is yes, but the details matter for understanding what that means in practice.

Is Cursor AI a fork of VS Code?

Quick Answer: Yes, Cursor is built on top of VS Code's open-source codebase (Code OSS), maintaining compatibility with VS Code extensions and settings while adding AI-native features throughout the editor.

Microsoft releases VS Code under two forms. The branded VS Code application has Microsoft-specific additions and telemetry. The underlying Code OSS project is fully open source under the MIT license. Cursor builds on Code OSS, which is legal and common practice.

This fork approach means Cursor inherits VS Code's mature editing capabilities, extensive language support, and years of stability improvements. The Cursor team then adds AI features deeply integrated into this foundation rather than bolted on as extensions.

Why did Cursor choose to fork VS Code?

Quick Answer: Forking VS Code gave Cursor a battle-tested editor foundation with millions of users, letting the team focus development effort on AI innovations rather than rebuilding basic editor functionality.

Building a code editor from scratch takes years. Editor fundamentals like syntax highlighting, file management, debugging integration, and extension systems require enormous engineering effort. By starting with VS Code, Cursor avoided reinventing solved problems.

The VS Code foundation also means developers face minimal friction when trying Cursor. Your muscle memory, keyboard shortcuts, and workflow patterns transfer directly. This familiarity reduces the switching cost that kills many new developer tools.

‍

How closely does Cursor track VS Code updates?

Quick Answer: Cursor regularly incorporates VS Code upstream updates to maintain compatibility and security, though AI integration work sometimes delays adoption of the latest VS Code features by a few weeks.

The Cursor team monitors VS Code releases and merges relevant changes into their fork. This keeps Cursor current with editor improvements, security patches, and new capabilities.

However, some VS Code updates require adaptation to work with Cursor's AI features. Deep integrations between the AI system and editor functionality mean changes cannot always merge automatically. The team balances staying current with maintaining stability.

What Does the VS Code Foundation Mean for You?

The practical implications of this architecture affect daily development work.

Do VS Code extensions work in Cursor?

Quick Answer: Most VS Code extensions install and work identically in Cursor because both editors share the same extension API and architecture, with only rare compatibility exceptions.

Extension compatibility ranks among the biggest advantages of Cursor's approach. Your favorite themes, language servers, debuggers, and productivity tools generally work without modification. You install them through the same process and configure them the same way.

The extensions marketplace accessible from Cursor includes the same options available in VS Code. Cursor also maintains compatibility with extension settings, meaning your existing configuration files often work directly.

Occasionally, extensions with deep VS Code integration have minor issues. These typically involve extensions that rely on specific VS Code internals that Cursor modified for AI integration. The Cursor team tracks these issues and works with extension developers on fixes.

If you're planning to install it yourself and test extension compatibility firsthand, this guide on how to install and set up Cursor AI walks through the full setup process.

Can I migrate my VS Code settings to Cursor?

Quick Answer: Yes, Cursor can import your VS Code settings, keybindings, and extensions automatically, making migration a one-click process that preserves your existing configuration.

When you first launch Cursor, it offers to import your VS Code configuration. This transfers:

• User settings and preferences
• Keyboard shortcuts and custom bindings
• Installed extensions
• Themes and appearance settings
• Workspace configurations

The import process handles most configurations correctly. Complex setups with custom paths or machine-specific settings occasionally need manual adjustment.

Does Cursor use the same keyboard shortcuts as VS Code?

Quick Answer: Cursor maintains identical default keyboard shortcuts to VS Code and adds new shortcuts for AI features, which you can customize using the same keybinding system.

Your muscle memory transfers completely. Command palette, file navigation, multi-cursor editing, and all standard shortcuts work exactly as expected.

Cursor adds new shortcuts for AI-specific features. The chat interface, inline editing, and Composer have dedicated keybindings. These additions do not override existing VS Code shortcuts, so you learn the new capabilities while keeping what you know.

How Does Cursor Differ from VS Code?

While the foundation is shared, significant differences exist in what each editor prioritizes.

What features does Cursor add beyond VS Code?

Quick Answer: Cursor adds native AI chat integration, codebase-aware autocomplete, multi-file AI editing, natural language commands, and built-in support for multiple AI models including GPT-4 and Claude.

The core differences center on AI integration depth:

• Chat interface: A built-in panel for conversing with AI about your code, including the ability to reference specific files, functions, or errors in your questions.
• Composer: A feature for creating or modifying code across multiple files through natural language descriptions, with diff previews before applying changes.
• Codebase indexing: Automatic analysis of your project structure that gives AI context about your entire codebase rather than just the current file.
• Inline editing: The ability to select code and request modifications directly without leaving your editing context.

For a deeper look at everything Cursor adds beyond the VS Code foundation, you can explore the full list of Cursor AI features in real workflows.

These features require integration impossible to achieve through extensions alone. The VS Code extension API does not expose the hooks necessary for this level of AI integration.

‍

Can you get Cursor-like features in VS Code with extensions?

Quick Answer: Extensions like GitHub Copilot and Continue add AI features to VS Code, but they cannot match Cursor's integration depth because the extension API limits what is possible.

GitHub Copilot provides autocomplete and some chat capabilities. It works well for suggestions but cannot understand your full codebase the way Cursor does. Multi-file editing and deep context awareness require access VS Code extensions do not have.

Continue and similar extensions push the boundaries of what extensions can achieve. They offer chat interfaces and some context awareness. But fundamental limitations in the extension system prevent matching Cursor's integrated experience.

This explains why the Cursor team built a fork rather than an extension. The features they wanted to create required modifying the editor itself.

Is Cursor as stable as VS Code?

Quick Answer: Cursor maintains high stability due to its VS Code foundation, though new AI features occasionally introduce bugs that the team typically patches within days of user reports.

VS Code's stability comes from years of development and millions of users finding edge cases. Cursor inherits this foundation, meaning core editing functionality works reliably.

AI features represent the newer, less battle-tested parts of Cursor. The Composer, chat integration, and codebase indexing occasionally encounter issues. The team releases updates frequently, and the community actively reports problems through Discord and GitHub.

For production development work, Cursor stability satisfies professional requirements. At LowCode Agency, developers use various AI-assisted tools depending on project needs, and Cursor works reliably for daily development tasks.

Does Being a Fork Create Any Problems?

Understanding potential downsides helps make informed decisions.

Will VS Code changes break Cursor in the future?

Quick Answer: The risk exists but is mitigated by Cursor's active maintenance and the stability of VS Code's extension API, which Microsoft maintains for backward compatibility.

Microsoft has strong incentives to keep the VS Code extension API stable because thousands of extensions depend on it. Breaking changes would anger their own ecosystem. This stability extends to forks like Cursor.

The Cursor team monitors VS Code development closely. If Microsoft announced changes that would affect Cursor, the team would have time to adapt. The open-source nature of Code OSS means Cursor can always continue from any point in the codebase.

‍

Does Cursor receive security updates as quickly as VS Code?

Quick Answer: Cursor incorporates security patches from VS Code regularly, though there may be a brief delay between Microsoft releasing a fix and Cursor updating their fork.

Security-critical updates receive priority attention. The Cursor team understands that developer machines contain sensitive code and access credentials. When VS Code releases security patches, incorporating them into Cursor becomes urgent work.

The typical delay measures in days rather than weeks for critical issues. Non-critical updates may wait for the next regular release cycle.

‍

Could Microsoft block Cursor from using VS Code code?

Quick Answer: No, the MIT license governing Code OSS permanently grants the right to fork and modify the code, with no ability for Microsoft to revoke this permission.

Open-source licenses like MIT provide strong legal protections. Once code releases under MIT, anyone can use, modify, and distribute it. Microsoft cannot retroactively change the license or prevent forks.

Microsoft has shown no interest in restricting VS Code forks. Their business model benefits from VS Code ecosystem growth regardless of which editor people use. Extensions, languages, and tools developed for VS Code work across the ecosystem.

What if you need to switch back to VS Code?

Quick Answer: Switching back requires no data migration since your code files remain unchanged, and Cursor's settings format closely matches VS Code, making the return straightforward if needed.

Your code lives in regular files that both editors open identically. Git repositories, file structures, and project configurations work in either editor.

Cursor-specific settings would not transfer back, but these primarily concern AI features that VS Code does not have anyway. The transition back is essentially just opening your project in VS Code instead of Cursor.

This reversibility reduces the risk of trying Cursor. You can evaluate it thoroughly knowing you can return to VS Code without losing work.

For teams evaluating governance, compliance, and deployment at scale, this overview of Cursor for enterprise explains how it fits larger environments.
