What it is

Theia IDE is an open-source, AI-native development environment for cloud and desktop, built on the Theia Platform. Users can select cloud, self-hosted or local AI models and create custom agents. It integrates official SDKs for providers including OpenAI, Anthropic and Google, and sends AI data to the provider the user chooses. The IDE supports VS Code extensions through Open VSX, though some Microsoft-proprietary extensions are unavailable and some extension API features may not work as expected. Language support uses the Language Server Protocol, including for Python, Java, JavaScript and C++. Workspace Trust puts untrusted folders in Restricted Mode and disables features that could execute code or read sensitive workspace content, but the project says this protection is still maturing. The IDE does not collect or transmit user activity, project details or code, though it can check for IDE and extension updates. The ready-to-use IDE is free at free. Its online demo is limited to 30 minutes per session. The modular Theia Platform can be used to build customized or white-labeled cloud and desktop IDEs and tools.
