The record

What it is: Theia IDE is an open-source, AI-native IDE for cloud and desktop, built on the Theia Platform.
AI models: Theia IDE lets users choose cloud, self-hosted, or local AI models and create custom agents.
AI providers: Theia integrates with official SDKs for providers including OpenAI, Anthropic, and Google, and sends AI data to the provider the user chooses.
Telemetry: Theia IDE does not collect or transmit user activity, project details, or code, though it can check for IDE and extension updates.
Workspace security: Workspace Trust uses Restricted Mode for untrusted folders and disables features that could execute code or read sensitive workspace content.
Trust limitations: Workspace Trust is still maturing; some extensions with limited untrusted-workspace support are treated as supported, and some subsystems may need more integration.
Extensions: Theia supports VS Code extensions through Open VSX, but some Microsoft-proprietary extensions are unavailable and some extension API features may not work as expected.
Languages: The IDE uses the Language Server Protocol for support of languages including Python, Java, JavaScript, and C++.
Customization: The Theia Platform is modular and allows adopters to build customized or white-labeled cloud and desktop IDEs and tools.
Platforms: Theia IDE offers desktop downloads for Windows, Linux, and macOS, plus an online demo and an experimental Docker image for online hosting.
Online demo limit: The online test version is limited to 30 minutes per session.
Support: Community help is available through GitHub Discussions, and professional support, training, and development services are offered by contributing companies.
Intended users: Theia IDE is a ready-to-use general-purpose IDE, while the Theia Platform is aimed at building customized or domain-specific IDEs and tools.
