### AI-Native IDE (Beta)

Experience the future of development with the AI-native Theia IDE, the open alternative to Github Copilot, Cursor etc. Built on Theia AI, our AI-first approach offers unmatched transparency and control, allowing you to customize AI interactions, choose your preferred models—whether cloud-based, self-hosted, or local—tailor prompts to your workflow, and even create your own custom agents to automate individual workflows, all while maintaining full ownership of your data.

### Language Support

Experience world-class code editing support in Theia IDE, integrated with the Language Server Protocol (LSP). Develop in almost any programming language, including Python, Java, JavaScript, C++, and more—all within one environment.

### Open Source and Vendor Neutral

The Theia IDE is backed by a diverse and healthy open source ecosystem and is an open alternative to VS Code (not a fork). Enjoy the added confidence of a fully open-source platform governed by a vendor-neutral community. Deploy and enrich your toolset on your own terms.

### Modern UX

Elevate your development workflow with Theia IDE's flexible workbench layout and user experience. Featuring theming support, a dynamic toolbar, detachable views, and efficient tab management, our web-based interface is designed to adapt to your needs, streamlining your projects for optimal productivity.

## Extensible and Open

The Theia IDE is built upon the highly modular Theia platform, enabling the integration of custom extensions and the creation of fully tailored tools (see examples below). Explore the Theia Platform and learn how to create custom tool offerings with ease!

While Theia incorporates certain components from Visual Studio Code, such as the Monaco editor, it is independently developed with a unique, modular architecture, **Theia is not a fork of VS Code**.
