Personal Music Server Made Easy

A one-click Mac app that turns your local music collection into a streamable server (OpenSubsonic protocol) accessible on your LAN or via Tailscale from anywhere. Works with local files, Apple Music, Plex, and more.

Navidrome already does this as free, open-source software with strong community adoption, and that's the core problem here — the addressable market is people who want this but won't self-host, which is real but small. The timing angle is mild: Apple's deprecation of iTunes Match features and ongoing frustration with streaming library matching keeps a trickle of users looking for local-first alternatives. A $5–15/month charge for a polished Mac app wrapper around OpenSubsonic is plausible if the UX genuinely eliminates the friction of running a server, but the ceiling is low, which is why $500–2k/mo is realistic rather than conservative. The biggest risk is that the target user — someone with a large local collection who cares enough to pay — is also technical enough to just run Navidrome or Jellyfin for free, leaving too thin a slice willing to pay for convenience.
