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
Hello, Product Hunt!
Mastra (YC W25) just released stable 1.0 for building AI apps and agents, announcing 300,000+ weekly npm downloads and 19,400+ GitHub stars, and they keep the momentum going launching today on @Product Hunt. LFG!
I had a blast working on this launch with @calcsam @smthomas3 @bookercodes and team. Read the behind-the-scenes in /p/mastra and give them a star on GitHub.
Oh and @bookercodes and I will be live on an X Space today at 3 PM UTC / 4 PM CET / 10 AM EST to talk about the launch ops. Tune in!
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
If you want to learn more:

- And our docs: https://mastra.ai/docs
You can get started with `npm create mastra@latest`. Excited to share Mastra with everyone here – let us know what you think!
@calcsam humble to work on this launch with you 🙏
@sam_bhagwat congrats on the launch! Is it possible somehow to plug in existing agents or all need to be created with Mastra?
Progressively
The easiest and most comfortable way to start building products with AI 🤩
@mfrachet lfg! above all, what's the #1 feature that you enjoy the most about @Mastra?
Progressively
@fmerian the capability to visualize very complex operations (aka the studio displaying workflow interactions for example)

@fmerian @mfrachet Good answer!
@bookercodes what's yours, Alex? you have to pick just 1

Hey, that’s my face on the demo thumbnail!
Stoked to be launching on Product Hunt today. 🔥 For the past 6 months I’ve been learning how to build agents with Mastra and sharing everything on YouTube as I go.
Beyond having everything you need out of the box, what really makes Mastra special is education. We put a lot into docs, guides, videos, workshops, and talks so you can quickly get to the concepts that actually matter. If you're new to (vibe) coding agents, Mastra is a great place to start.
It also helps you ship to production faster. Mastra is built on established patterns and gives you “white spots” to plug in your own agent logic, so you spend more time building and less time wiring things together. If you need RAG, HITL, evals - Mastra has a primitive for it, and they all play nicely together.
The local development environment, Studio, really shows how well everything works together. Run `npm create mastra` to spin up a default weather agent and poke around - it feels playful, and I’m pretty sure you’ll learn something new.
@bookercodes 🐐
The combination of workflows, evals, and tracing in one place stands out. How opinionated is Mastra about how agents are structured?

@shreya_chaurasia19 Mastra is flexible! It supports: tool-calling agents, agent networks (multiple agents that can collaborate), and workflow orchestration when you need fine‑grained control over complex flows. So you can start simple and gradually add structure as your use case becomes more advanced.
I use Mastra to help automate daily report building for potential investments. I love the strongly typed systems and the studio debugging tools.
