Mastra (YC W25, from the Gatsby team) is the leading TypeScript agent framework: durable workflows, built-in memory and RAG, tool calling with Claude and other models, evaluation hooks, and MCP client/server support. The natural fit for teams standardizing on TypeScript who outgrow hand-rolled agent loops.

What it does

  • TypeScript agent framework: agents, workflows, RAG, evals and memory in one stack
  • Scaffold a project with npm create mastra@latest
  • Ships with a local playground (Studio) for testing agents and workflows
  • Provider-agnostic model routing through the AI SDK ecosystem

When to use it

For TypeScript/JavaScript teams who want a batteries-included agent framework — graph workflows, memory, evals — instead of assembling LangChain-style pieces themselves.

Getting started

npm create mastra@latest

Follow the interactive prompts; the Installation guide on mastra.ai/docs covers CLI and manual setup.

Things to know

Opinionated framework — projects built on it follow Mastra's structure, which is a commitment.
