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
Mastra (YC W25) is launching on Product Hunt today, releasing stable 1.0 for building AI apps and agents, and announcing 300,000+ weekly npm downloads, 19,400+ GitHub stars, and production use at companies like @Replit and @WorkOS.
I had a blast working on this launch with @calcsam @smthomas3 @bookercodes and team, and wanted to share with you some thoughts we put into the ops.
Hi Product Hunt, we're Sam, Shane, and Abhi, and we're building @Mastra, the open-source JavaScript agent framework.
We are excited to announce today we released Mastra 1.0 in stable. Mastra lets you create multi-agent workflows, run evals, inspect in a local studio, and emit traces.
We started Mastra about 15 months ago and now it’s grown to over 300k weekly npm downloads and 19.4k GitHub stars. It’s now Apache 2.0 licensed and runs in prod at companies like @Replit, PayPal, and@WorkOS
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.
