A code library from the LangChain team for building AI agents that can pause, remember where they were, and pick back up later — even after a server restart — instead of losing all progress if something goes wrong mid-task.

Best alternatives to Mastra in 2026
An 'AI agent' is a program that uses AI models to carry out multi-step tasks on its own — answering customers, searching documents, filling forms. Mastra is a toolbox for developers who work in the JavaScript/TypeScript world, giving them the ready-made building blocks to create such agents without reinventing the basics every time. Mastra is an open-source TypeScript framework for building AI agents, workflows and AI-powered applications. Agents are defined with typed instructions, models and tools; workflows are graph-based with explicit control-flow primitives (branching, loops, human-in-the-loop pauses); and a model router abstracts 90+ providers including OpenAI, Anthropic and Gemini behind one interface. The framework ships the production plumbing most agent projects end up rebuilding: a memory system for conversation history and retrieval, RAG integration, built-in observability with traces, metrics and evals, and support for authoring MCP servers. It integrates with React, Next.js and Node.js or deploys as a standalone server, and scaffolds new projects via npm create mastra. The core is Apache 2.0 with no seat or usage limits; some enterprise features use a separate Mastra Enterprise License that is free for development but paid in production, and a hosted cloud offers Starter and Teams tiers. With 26k+ GitHub stars it has become the reference agent framework for the TypeScript ecosystem.
