Mastra is the easiest way to build a production AI application, built by the team that brought you Gatsby. We provide a complete set of AI primitives: workflows for complex operations, agents for autonomous decisions, RAG for knowledge integration, and evals for quality & accuracy. Mastra is open-source, modular, and built in Typescript for product developers. You can deploy Mastra on any cloud, and it gives you a straightforward syntax to solve the hardest problems building with AI: human-in-the-loop workflows, agent memory and tool selection, and output quality.

Mastra is a TypeScript-first AI framework designed to build and deploy advanced AI-powered applications with capabilities such as autonomous agents, durable workflows, and robust memory handling. It offers a comprehensive developer SDK, CLI, and cloud platform that support building agents with clear instructions, long-term memory, tool integration, and workflow orchestration for complex multi-step processes.

Key features include a unified provider API enabling seamless switching between over 800 models from 47 providers through a single interface, persistent and real-time context management using vector stores and retrieval-augmented generation (RAG), and the ability for agents to call external tools and execute functions for extended automation. Its durable workflows support graph-based state machines with suspend/resume capabilities and real-time monitoring streams, facilitating long-running tasks with traceable steps.

Mastra also provides production-grade observability tools that capture performance metrics, workflow tracing, and evaluation capabilities to monitor and refine AI agents in deployment. The framework is built specifically for TypeScript, offering strong typing, IDE autocomplete, and integration with popular provider SDKs to enhance developer experience. It supports creating various AI applications such as conversational agents, domain-specific copilots, workflow automations, and decision-support tools that combine language understanding, reasoning, and action.

Developers can leverage Mastra’s open-source SDK for local development and testing, then deploy to Mastra Cloud for scalable production use with built-in monitoring and observability. This setup enables continuous measurement and refinement of agent behavior, making it well suited for production AI environments requiring flexibility, durability, and extensibility.
