TypeScript-native agent framework built for Next.js and edge deployment.

Source Docs Website

Overview

Mastra targets the full-stack TypeScript developer who does not want to stand up a Python service to run an agent. Workflows, RAG, evals, and agent memory ship as TypeScript primitives that deploy to serverless and edge runtimes alongside the app they belong to.

Why it's indexed

Keeps the agent in the same language and deployment target as the web app, removing a whole service boundary.

Editorial judgement, not a measurement — see our methodology. Listing is never paid for.
