Mastra is a modern TypeScript framework for building AI-powered applications and autonomous agents. It provides model routing, workflow orchestration, RAG, and tooling integration for both frontend and backend environments.

Use cases

• Create autonomous AI agents that can call tools and APIs.
• Build multi-step AI workflows with conditional branching and parallel execution.
• Integrate large language models from multiple providers through a unified interface.
• Add human-in-the-loop approval steps to AI processes.
• Develop AI-driven web applications with React or Next.js using built‑in observability.

When to choose

• You need a TypeScript‑first solution for AI agents and complex workflows.
• You want to switch between many LLM providers without changing code.
• Your project requires built‑in support for RAG, memory, and human‑in‑the‑loop features.
• You prefer a framework that works both on the server (Node) and the client (browser).

When to avoid

• You are looking for a pure Python or Java ecosystem.
• Your application does not involve AI or LLM integration.
• You need a lightweight library without the additional workflow and observability layers.
