Mastra AI

Mastra AI is the open-source, TypeScript-first framework for building and deploying production-ready AI agents and complex, durable workflows.

This is Mastra: the AI engineering framework built for the modern TypeScript stack. It provides a complete set of AI primitives: Agents for autonomous decision-making, Tools for external actions (APIs, databases), and graph-based Workflows for orchestrating multi-step processes like human-in-the-loop approvals. Developed by the team behind Gatsby, Mastra handles production essentials like Model Routing (connecting to 40+ providers: OpenAI, Gemini, Anthropic), RAG for knowledge integration, and built-in Evals for quality assurance. Use it to automate support, generate financial documents, or build domain-specific copilots; deploy agents seamlessly to Next.js or any Node.js environment.
