Skycast is a shareable working prototype built from a SayCraft conversation: a running web app with a live preview URL, not a static mockup or meeting notes. A team described it in a real product discussion and SayCraft generated the deployable app as they talked. The goal: Build a sleek weather app with a dark cyberpunk theme, neon-on-near-black visuals, and a sci-fi console feel.. This page is the full build replay.
