Show HN: I built a universal robot renderer in the browser

I was trying to build a website for sharing robotics projects and realized the coolest way to visualize a robot is in 3D.
I could only find a few open-source projects that did this, but each was for a specific environment (think MJCF vs URDF vs USD) and some were damn hard to run. I know Next.js so I decided to merge them all and call it mechaverse.
I wanna fix bugs and make the viewers faster so please test it and break it.
1) Compress to one outcome line (“Render URDF/MJCF/USD robots instantly in your browser”) + a mini proof strip. 2) Make the CTA specific and low-risk (e.g., “Open demo in 1 click — no signup”), with a 3-Q mini-FAQ beside it.
I can ship a 12–24h patch with 8–10 concrete fixes and paste-ready copy. €290.
If useful, reply “yes” and the primary goal for the page. I can start today. —Rudi
Though another good reason would be that theres a lot of web assembly and stuff going on making it more difficult. For example, I couldn't get the USD and MJCF viewers working natively in React like the URDF viewer so I settled for iframe's with pub/subs for communication.
Though if someone knows a better way than I'd love to hear from em haha.
Here's the github btw: https://github.com/jurmy24/mechaverse
