Mastra is a TypeScript framework and platform for building, deploying, and observing AI agents and AI-powered applications.

Mastra provides a modern TypeScript framework for developing AI agents and applications. It includes tools for building agent workflows, an observability platform (Studio) to evaluate and improve agent performance, and a cloud deployment server. The framework supports defining custom evaluations, tracking performance, processing inputs/outputs to prevent prompt injection, and tracing agent calls and token usage. The platform also offers a Memory Gateway to add memory capabilities to agents, regardless of the framework used. Mastra is open-source under the Apache 2.0 license, allowing flexible deployment. It integrates with various server frameworks like Next.js, Express, and Hono, and provides templates and learning resources for quick starts.
