SUB/WAVE turns your music library into a real radio station: one shared stream, an AI DJ that picks tracks, reads idents and takes requests in plain language. Self-hosted, works with local LLMs, MIT licensed. Web, iOS, Android and desktop players.
Hey Product Hunt 👋
I'm Parminder, and for the last three months I've been building the radio station I always wanted.
Streaming apps gave us infinite choice and somehow made music lonely. Everyone sits in their own algorithmic bubble. I missed radio: one broadcast, everyone hearing the same song at the same time, a voice between tracks that makes it feel alive.
SUB/WAVE is that, self-hosted. Point it at your music library (Navidrome or any Subsonic server), give it an LLM (a local Ollama model is enough) and you get a 24/7 station: an AI DJ picks the tracks, does station idents, reads the time and weather, and takes song requests in plain language. People tune in from the web player, native iOS and Android apps, a desktop app, or anything that plays an MP3 stream, including Sonos and car radios.
Some things I'm proud of:
- It's radio, not a playlist. No skip button, no per-listener shuffle. You tune in and hear whatever's on.
- Transitions are ending-aware. The DJ knows whether a song fades out or ends cold, and can even blend stems between tracks.
- DJ personas, guest co-hosts with banter, and produced programmes with per-episode plans.
- Everything can run locally: LLM via Ollama, local TTS, your own music files. No cloud required.
- MIT licensed. 48 releases in three months, and it just hit 1.0 this week.
There's a live demo station if you want to hear it before installing anything: https://www.getsubwave.com/listen
I'd love to hear what you'd want from a station of your own. I'll be around all day answering questions.
10/10 excellent project and incredible dev behind it.
Love the self-hosted angle and the AI DJ taking plain-language requests is a great touch. One thing I'd love: a "discover from my own library" mode where the DJ only pulls from tracks you haven't played in a while, so it actually helps you rediscover music instead of leaning on the same favorites.
I probably wouldn’t replace Spotify with this, but I do like the idea of turning a personal music library into something that feels alive instead of just another playlist. The shared stream and local setup give it a character most music apps have lost. Congrats on the launch!
It looks good, but a problem for me and for most people now i guess is that we don't store our music files, just use spotify or apple music
