It runs entirely in the browser, with no sign-up and no uploads. **Try it:** [https://winchxyz.github.io/mosaiz/](https://winchxyz.github.io/mosaiz/) **How the vibe coding actually went** 1. **One big prompt to start.** I wrote one long message: what the app should do, every mode I wanted, and "think like a senior web dev, 3D designer, UX designer and marketer". Claude Code (Opus) didn't start coding right away. It first wrote the shared data contracts, then split the work across 6 parallel Sonnet agents (engine,…
