Mastra
VerifiedTypeScript framework for building production-ready AI agents and apps.
What is Mastra?
Mastra is an open-source framework that enables developers to construct AI-powered applications and agents using a TypeScript-first approach. It bundles essential components such as model connections, agent reasoning loops, graph-based workflows, and context handling to support reliable AI behavior across different stages of development.
The system operates by letting users define agents that interact with tools and models, orchestrate steps through explicit workflow controls, and maintain state for human oversight or long-running tasks. Integrations allow these components to embed into existing web stacks or run independently as servers, with additional support for protocol-based tool exposure and performance monitoring.
It targets TypeScript developers and teams building AI features who need structured patterns for agents, production monitoring, and frontend-backend connectivity without starting from scattered libraries.
What you can build with Mastra
Autonomous task agents
Create agents that reason through goals, select tools, and iterate until reaching a solution for open-ended problems.
Multi-step process orchestration
Design graph workflows that branch, run in parallel, or pause for approvals using explicit control flow syntax.
Web app AI integration
Embed agents into React or Next.js interfaces with memory features and UI libraries for interactive assistants.
