Original Summary

I built Vocafy, a music player web app for Vocaloid songs. You pick songs by producer, singer (voicebank), or year, and it plays the original videos from YouTube and Niconico.<p>Around 2010-2012, at the peak of the Vocaloid boom, I made music videos for a Vocaloid producer. I skipped university for days to edit videos, and it was honestly the most fulfilling time of my life. Lately Vocaloid songs seem to be showing up on YouTube again, so I thought now was the time to give something back. I built it together with Claude Code.<p>In my opinion, Vocaloid is mainly about the songs, not the videos. But there aren&#x27;t many services focused on the songs. YouTube and Niconico are video services. YouTube Music mixes covers and unauthorized reuploads in with the originals, and its search isn&#x27;t great, so it&#x27;s hard to reach the song you want among the huge number of Vocaloid songs.<p>Features:<p>- Browse by voicebank, year, or producer<p>- Favorite songs and producers (sign in with Google to sync across devices)<p>- Continuous play, shuffle, and radio<p>- A picture-in-picture-like mini player<p>- Sleep timer<p>- Both YouTube and Niconico<p>- Add to home screen to use it as an app (Android, iOS, PC)<p>- Theme colors based on Vocaloid characters<p>Because of technical limits, background playback and continuous Niconico playback on iOS Safari are hard to support.<p>As of October 2026 there are about 30,000 songs, 800 producers, and 700 singers, and I add more every week. It&#x27;s completely free. If a song you&#x27;re looking for is missing, let me know.<p>English isn&#x27;t my first language, so I wrote this in Japanese and used AI to translate it.
