Jellify-Music/App
A cross-platform, free and open source music player for Jellyfin, powered by React Native
Jellify is a React Native music player for self-hosted Jellyfin servers, available on both app stores. It targets people who run their own media server and want a mobile experience close to what Spotify or Apple Music deliver, including CarPlay and Android Auto. If you don't already run Jellyfin, this is not for you.
CarPlay and Android Auto support are genuinely rare in open-source mobile apps and the implementation looks complete, not bolted on. The storage layer choices are good — MMKV instead of AsyncStorage is the right call for a media app that holds a lot of cached state. Gapless playback is technically harder than it sounds and most DIY players skip it; this one has it. Telemetry is opt-in by default and well-documented with a clear three-tier logging model, which is more than most apps bother with.
Self-signed certificates aren't supported until 1.3.0 (September '26), which is a real gap — home lab Jellyfin setups frequently use self-signed certs behind a local domain, and telling those users to wait a year is friction at the exact audience this app is for. Google Cast is flagged as 'still in early stages' in the README, so don't count on it working reliably. Tablet support is pushed to 2.0 in December '26, meaning iPad users get a stretched phone layout for at least another six months. The OTA update mechanism ships code outside the app store review cycle, which is clever for fast iteration but means users need to trust the bundle server as much as the app itself.
