Hey Product Hunt — I’m Alex, the maker of Mirasonic. I built it because I wanted to keep using the music client I already like, without rebuilding background playback, queues, lock-screen controls, AirPlay, or offline caching. Mirasonic is a self-hosted Subsonic server: it lets a compatible client search and play YouTube Music anonymously, while playlists, stars, and listening history live in a local SQLite database. It does not use a Google account or browser cookies. It’s free and open source. The limits are deliberate: it is intended for one listener on hardware you control; age-restricted tracks won’t play; and it must sit behind Tailscale, WireGuard, or a TLS-terminating reverse proxy — not be exposed directly to the internet. I’ve been running it personally for three weeks. I’d especially value feedback from people using Symfonium, substreamer, play:Sub, or another Subsonic client: what works, what doesn’t, and which client behavior I should test next.
