About
Mastra is an open-source TypeScript and JavaScript framework for building, testing, and deploying AI agents and applications. It provides observability, evaluation, and deployment tooling so developers can tune agent performance and expose agents as APIs. The framework integrates with popular server frameworks like Next.js, Express, and Hono, and is licensed under Apache 2.0.
Problem
Building, testing, and deploying AI agents in production requires robust tooling for observability, evaluation, and infrastructure integration that most frameworks lack.
For
TypeScript and JavaScript developers building AI agents and applications
How it works
Developers scaffold an agent project via npm, define agents and evaluations in TypeScript, and deploy them as APIs or bundled with their existing app using Mastra's built-in deployment and observability platform.
