Mastra is an all-in-one TypeScript framework for building AI-powered applications and agents. It supports core agent patterns like tools, workflows/orchestration, RAG, memory, MCP integration, and evals, designed to go from prototype to production inside your own codebase. Mastra also offers an optional Mastra Cloud/Platform experience with a Studio for testing agents and workflows plus AI-focused observability (structured logs, tracing, and eval dashboards) and deployment integrations.

What the evidence says about Mastra

Mastra is an open-source TypeScript framework and optional hosted platform for developers building AI agents and applications; it is not a ready-made agent. It provides agent, tool, workflow, memory, MCP, evaluation, observability, and deployment primitives across many model providers.

Verified capabilities

  • Stateful agent primitives

    Mastra agents support model routing, tools, MCP, persistent and semantic memory, logs, traces, and evaluation hooks.[2]

  • Durable workflows and agent networks

    Developers can compose explicit sequential, parallel, branching, suspendable workflows or coordinate agents for open-ended collaboration.[1], [2]

  • Flexible application deployment

    Mastra applications can integrate with React, Next.js, and Node, run as standalone servers, or use managed deployments and observability on Mastra Platform.[1], [3]

Research coverageExact counts from this profile; bars are relative to the largest count shown.

Where it fits best

  • TypeScript developers building stateful agents, agent networks, or durable multi-step workflows with tools and production observability.[1], [2]

Buying and deployment notes

The Apache-2.0 framework is free to self-host. Mastra Platform Starter is $0 per month with included usage and metered overages; Teams is $250 per month and Enterprise is custom.[3]

Platforms: TypeScript framework, Mastra Studio, Mastra Platform[1], [3]

Deployment: Self-hosted on a Node-compatible platform, Mastra-managed deployment[1], [3]

Important considerations
  • Mastra supplies a framework rather than a finished agent; developers remain responsible for application behavior, model credentials and costs, tools, data, testing, and deployment choices.[1], [2], [3]
  • The hosted free tier includes usage allowances, after which observability, CPU time, egress, gateway, memory, and storage can incur metered charges.[3]

Reasoning: Mastra is a TypeScript framework for building AI agents rather than a standalone autonomous agent itself. While the framework provides extensive capabilities to enable autonomy in constructed agents—including agent networks for multi-agent collaboration, sophisticated memory systems with multiple storage backends, tool execution capabilities, workf...

Some of the use cases of Mastra:

  • Building TypeScript-based AI agents with tools, memory, and structured responses for real applications.
  • Orchestrating multi-step workflows (agent + tools + RAG) and evaluating reliability with built-in eval concepts.
  • Integrating MCP to connect agents to external tool servers and broader agent ecosystems.
  • Testing, deploying, and monitoring agents via Mastra Cloud’s Studio and AI-aware observability.
