Ragnar - Text to CAD models

Hey Convex community 👋

We’ve been building Ragnar for almost two years and we’re finally starting to share it more publicly.

Ragnar lets anyone create 3D CAD models from a simple prompt. You can iterate fast until it feels right, then export as STL (3D printing) or STEP (manufacturing).

We’re using Convex on the backend and it’s been a huge help for moving quickly—especially for storing projects, keeping iterations organized, and making the app feel responsive. I’d love feedback from this community on:

* the overall product + onboarding flow
* what you’d expect from “prompt → iterate → export” in a real workflow
* Convex best practices you’ve learned for scaling apps like this (happy to share details too)

If you create an account today you will get 15 free credits that you can experiment with 😃 Would love to see what you guys create in this thread đŸ’„
