About Mastra

At its core, Mastra is an open-source TypeScript framework for agents, workflows and RAG built on top of Vercel AI SDK patterns. In practice, it adds memory, observability, evals and a local development playground, and deploys to serverless or standalone servers. For teams moving agents from prototype to production, that focus on reliability and visibility matters more than adding another layer of fragile automation.
