What Is Mastra?
Mastra is a TypeScript framework for building AI agents and workflows, with a hosted platform for running them. The core framework is free, and most sources describe it as Apache 2.0 licensed, though two list MIT and another notes that enterprise features in ee/ directories are source-available under a separate Mastra Enterprise License and need a licence for production use. Check the GitHub repo.
Platform pricing is confirmed by Mastra's own pricing page and a July 2026 blog post, and third-party listings match. Starter is free, with 100K observability events, 24 CPU hours and 15 days of data retention. Teams is $250 a month with 1M events (then $8 per 100K), 250 CPU hours (then $0.25 an hour), 6 months of retention, multiple teams, SSO and SOC 2 documentation. A Server Always-On add-on at $100 per project keeps servers running around the clock. Enterprise is custom. Overage is billed beyond the allowances.
Mastra suits JavaScript and TypeScript teams that want an agent framework in their own language. Because it is code-first, it fits teams comfortable with deploying services; those wanting no-code tools should look elsewhere. Compare Pydantic AI, LangGraph and Agno.
