Mastra

Mastra: The open-source TypeScript framework for building and scaling AI agents, featuring durable workflows, RAG, and a unified router for 40+ LLM providers (OpenAI, Gemini).

Mastra is the leading open-source TypeScript framework for AI agents, launched in 2024 by Gatsby veterans Sam Bhagwat, Shane Thomas, and Abhi Aiyer. This structured platform streamlines AI engineering: it provides autonomous Agents, graph-based Workflows for complex orchestration, and RAG pipelines for grounded responses. The unified model router connects to 40+ LLM providers (e.g., OpenAI, Gemini). Backed by $13M from investors like Y Combinator, Mastra delivers production essentials: built-in Evals, Observability, and a local development playground.
