Developer chadMueller shares how he built Nostalgex, an MIT-licensed open-source app that turns Plex/Jellyfin/Emby libraries into 90s-style live cable channels with a real guide UI. Stats: 130+ channels, 1,400+ Apple TV downloads, 260 hours watched in a week, 735 commits, 7 contributors, now porting to Roku. His Claude workflow: write the experience spec first, keep channel rules in one JSON file instead of code, let Claude write one-off TMDB scripts, always test on real devices (the simulator lies), paste Discord bug reports straight into Claude, and use the Apple TV app as the spec for the Roku port.
