Theia IDE ✓

Theia AI is an open framework for building customizable, AI-native tools and IDEs, designed to give developers complete control over AI integration. As part of the broader Theia Platform, it supports both cloud and desktop environments and is the foundation for the AI-powered Theia IDE—an open-source development environment offering transparency, flexibility, and full control over AI interactions.

Theia AI enables developers to create domain-specific AI agents capable of complex, multi-turn conversations with native access to tool components. These agents can be embedded with advanced features like custom user interfaces, structured change sets, and interactive workflows. Developers can also define the agent’s context by integrating external APIs, databases, or scoped data, such as files or symbols dragged into a chat window.

The framework is model-agnostic, supporting cloud-hosted, local, and self-hosted language models, as well as external integrations like Anthropic’s Model Context Protocol (MCP). With advanced prompt management, custom UX components, and native context retrieval, Theia AI empowers teams to design sophisticated, workflow-aware AI experiences.

Ideal for teams building developer tools, technical editors, or complex automation systems, Theia AI provides the structure and adaptability needed to go beyond basic chat agents and embed intelligent behavior into modern, domain-tailored environments.
