I also have my own tool. I built a browser-based OpenSCAD harness. It’s a simple SPA with a chat loop. It stores everything in the user’s browser and requires the users to bring their own tokens (URL with API Key or OpenRouter with PKCE)

I host it here: https://vibe3d.spoerri.dev - my partner enjoys it because she can bring an idea to print pretty fast.

Maybe a similar idea could be interesting for KetchUp as well.
