From the team behind Gatsby, Mastra is a framework for building AI-powered apps and agents with workflows, memory, streaming, evals, tracing, and Studio, an interactive UI for dev and testing. Start building: npm create mastra@latest

I self host this and the reason is that the core is a library sitting in my own repo rather than a platform I have to live inside. Agents, workflows and tools end up next to the code that calls them, so I can read what an agent will actually do without opening a dashboard, which is most of what I want out of a framework. Being TypeScript the whole way through also means the same types cover the agent and the API route that triggers it.

The pricing shape is the problem more than the price. Free to $250 with nothing in between means a small thing that is real and in production has no plan to sit on, so I self host and they get nothing from me, which can't be what anyone wanted. The $100 always-on option is the closest thing to the missing rung and it's framed as an add-on rather than a plan, so nobody finds it.

Mastra turns AI agents from simple coding assistants into a full, open-source software delivery workflow.

The learning curve could be smoother, especially for beginners, with simpler setup and more practical examples.

Because of flexible approach and the ability to build and customize agent workflows without being locked into a closed platform.

Revolte runs a harness of specialized agents across the full dev lifecycle, so the framework underneath had to be production-grade, not a prototyping toy. Mastra's modern TypeScript stack gave us type safety, real workflow control, and structure we could actually build a platform on, without the sprawl and glue code that slows other frameworks down. A serious TypeScript foundation with clean agent orchestration is what set it apart.

Shoutout to the team at Mastra for building an excellent agent orchestration layer. Mastra is a key part of Imagine.dev’s agentic architecture, helping us coordinate specialized agents and reliably turn high-level intent into structured execution. Their focus on developer experience and composability made it possible for us to move fast without sacrificing correctness.

Really like the depth of product here, very hard to make a product of this scale high quality, impressed!
