yearincode - Spotify Wrapped for your GitHub year — no login needed

Every December my Spotify Wrapped shows up and I love it — a year of behavior turned into a story you actually want to share. Then it clicked: developers have a whole year sitting in git log, and nobody had built the fun version of it. So I built yearincode. Type any GitHub username (no login) and 15 seconds later you get an animated recap: commits, top languages, peak coding hour, longest streak, a discipline score, and your developer archetype out of 23 — from The Night Owl Refactorer to legendary all-time ones like The Architect and The OG. There's a "Since Day One" wrap for your whole career too. The process taught me a lot. I started sign-in-only, but a friend balked at the GitHub permission screen, so I rebuilt it to work from just a username — public data only, which turned out to be the right call for virality. The animated player is Flutter Web (wasm) embedded in a Next.js app, with Supabase behind it. Privacy was non-negotiable: it only ever reads public commit metadata, never your code, and a pasted token (for private totals) is used once and never stored. Built solo, in the gaps between my day job. Would love your feedback — try it on your own handle and tell me your archetype 🎁
