I built a 1v1 wizard duel game that runs entirely in your browser.
WebGPU. A real DualSense. Spells as jets of light, Clashes, destructible arenas.
Built with Claude Code. 🧵
There’s a 17-lesson training mode (with a live 3D demo of each move) that earns you a place in the Duelling Club before your first duel.
Play it now (Chrome/Edge + DualSense): spellbound-blush.vercel.app/
It’s open source. Every line was written with Claude Code: the duel simulation, the WebGPU shaders, the DualSense driver, the training mode.Star it, fork it, add a spell:

15min @typesafe Jeveloper tutorial 🧠
My team at @treg_ai has been using Jev a lot in prod:
- Classify web traffic
- Smart onboarding
- Jev-reranked search
~10x cheaper, 18x faster, 30% more accurate in our tests compared with GPT6-luna
OpenSourced our Jev implementation 👇 github.com/superdesigndev/tr…
I gave Claude Code (Opus 5.5) one night with my bail bonds SaaS.
By morning, in ~12 hours, it had made:
• 2 promo videos
• 71 narrated tutorials filmed in the real app
• 82 help pages
No video editor. Every frame is code.
How it works, with the stack and APIs 🧵
Every video lives on Vercel Blob under a content-hashed name. The only thing a publish changes in git is a manifest.
A new repo rule: any change a user can see updates its help page and re-films its tutorial in the same PR.
Docs that can't rot.
The whole stack:
Claude Code · Remotion · Playwright + CDP · ElevenLabs (TTS, SFX, Music) · ffmpeg · Vercel Blob · WebVTT
Watch them, plus the 71 tutorials:
