Mastra is an open-source TypeScript framework for building AI agents and workflows in Node.js. It provides first-class primitives for agents with tools and memory, durable workflows with branching and loops, RAG pipelines, model routing, evals, tracing, and local testing in Mastra Studio. The developer experience is TypeScript-native throughout, with typed tools, schemas, and workflow steps. It integrates with modern JavaScript frameworks like Next.js, React, Express, Hono, and SvelteKit, and can connect agents to external tools through MCP. For TypeScript developers who find LangGraph too Python-oriented and the Vercel AI SDK too low-level for complex agent products, Mastra fills the gap with a batteries-included backend framework.
