Oh Snap Hat Builder

Goal

Ordering a custom-branded hat usually means a slow back-and-forth of emailed logo files and vague mockups before you know what it’ll actually look like. Oh Snap exists to close that gap — and to prove a solo, vibe-coded build could look as premium as a funded product, not just work.

Solution

A live hat configurator: upload your artwork, choose the hat color, and watch it render stitched onto a realistic cap mockup in real time. Getting the look right took more than one prompt — I ran the design through several rounds of cross-LLM prompting, feeding one model’s output back into another for critique and refinement, until the UI held up next to real product photography.
