Mastra
A TypeScript framework for agents, workflows, and RAG, from the team behind Gatsby.
Mastra is an opinionated TypeScript framework that covers agents, deterministic workflows, RAG, and evaluations in one place. It is built for the JavaScript ecosystem, so it slots into existing Node and web codebases naturally.
It bundles the surrounding concerns (memory, tracing, deployment) rather than leaving them to be assembled, which makes it more of a batteries-included platform than a bare library.
Where it fits
The natural choice for TypeScript and Node teams who want agents in the same language and codebase as the rest of their app.
Where it does not fit
Not the path for a Python-first team, or one that wants to assemble each piece independently.
Alternatives to Mastra
The closest options on the map, and where each fits instead.
-
LangGraph Graph orchestration
Reach for LangGraph when an agent needs real branching (loops, retries, human-in-the-loop pauses) and you want that control flow written down explicitly.

-
OpenAI Agents SDK Lightweight agent SDK
A good fit when you want a minimal agent loop with handoffs and tracing, and you are already building on OpenAI models.
