Project overview

Mastra gives TypeScript developers one framework for model access, autonomous agents, graph-based workflows, and AI application development. It can integrate with React, Next.js, and Node or run as a standalone server, supporting a path from prototypes to deployed products through a common interface for many model providers. Most of the core uses Apache 2.0, but enterprise features under `ee/` require a commercial license for production.

Project overview

Eclipse Theia is a framework for teams building their own developer tools or cloud IDEs, rather than a single fixed editor. It can be composed into browser-based or desktop applications, offers a flexible extension architecture, and supports the VS Code extension protocol. The project also documents application composition, Theia extensions, VS Code-style extensions, and desktop packaging.
