Mastra: A TypeScript Framework for Rapid AI App Development

Mastra is an opinionated TypeScript framework for quickly building AI applications and features. It provides essential primitives: workflows, agents, RAG, integrations, and evaluations. Run Mastra locally or deploy to a serverless cloud. Key features include LLM model integration (supporting OpenAI, Anthropic, Google Gemini via the Vercel AI SDK), agent systems enabling LLMs to use tools and access data, typed tool functions, durable graph-based workflows, RAG knowledge base construction, pre-built third-party API clients, and automated evaluations. Get started with `create-mastra` and open the playground with `mastra dev`. Contributions are welcome!
