Mastra, a TypeScript framework for AI agents, launches with observability and deployment tools

Mastra is an open-source TypeScript framework (licensed under Apache 2.0) for building AI-powered applications and agents, with built-in observability and deployment capabilities.

The platform includes tools to trace agent calls and token usage, define custom evaluations using model-graded and rule-based methods, and deploy agents as APIs or bundled with applications via Next.js, Express, Hono, and other frameworks.

Mastra offers pre-built templates for use cases including browser automation (via Stagehand integration), Google Sheet analysis, and database querying with natural language.
