VibeSonic

VibeSonic is a lightweight, self-hosted music/media server written in Go. It follows the same philosophy as other small Vibe* tools: a single Go binary, SQLite storage, server-rendered Bootstrap 5 templates, dark mode by default, minimal JavaScript, and no external services (no Redis, no message broker, no microservices, nothing Kubernetes-specific).

This is Phase 2 of 4. Phase 1 built the foundation (config, schema, auth, scanner, metadata, streaming, cover art, web UI shell). Phase 2 adds a complete implementation of the original Subsonic REST API through version 1.16.1 under /rest/* — every endpoint, backed by real data, including transcoding, HLS, a real mpv-backed jukebox, and a real podcast subsystem. See docs/subsonic-compatibility.md for the full endpoint-by-endpoint matrix. OpenSubsonic extensions are not yet implemented (Phase 3).

Features

Phase 1: foundation

SQLite storage (WAL mode, foreign keys, versioned migrations) with a schema already modeling artists, albums, songs, genres, contributors, playlists, favorites, ratings, scrobbles, playback history, bookmarks, play queues, shares, podcasts, internet radio, and settings
Native authentication: Argon2id password hashing, HTTP-only signed session cookies, CSRF-protected forms, session revocation
Optional Navidrome-style external authentication via a trusted reverse proxy header, gated on the real TCP peer address (never on spoofable X-Forwarded-For/X-Real-IP/Forwarded headers)
A library scanner supporting multiple music folders, incremental rescans, new/changed/deleted/renamed file detection, and a bounded worker pool — never a blind full rebuild
Real metadata extraction via ffprobe (multi-artist, multi-genre, MusicBrainz IDs, ReplayGain, embedded artwork/lyrics, sort fields, and more)
Stable, opaque, URL-safe IDs that survive restarts and rescans
Direct media streaming with HTTP range request support, correct MIME types, and no full-file buffering
Cover art discovery (embedded artwork or folder images) with a resized-image disk cache
A server-rendered, dark-mode, keyboard-friendly web UI: browsing, search, playlists, favorites, a persistent bottom player, and an admin section (users, music folders, scanner status, system settings)
/healthz and /readyz

Phase 2: Subsonic REST API

All 76 endpoints of the original Subsonic API through 1.16.1 — browsing (filesystem and ID3), search, playlists, favorites/ratings/ scrobbling, sharing, user management with the full permission model, bookmarks, play queue, chat, and library scan status
Real ffmpeg-backed transcoding (mp3/opus/aac) and HLS segmenting for stream/hls, bounded concurrency, killed on client disconnect
A real podcast subsystem: RSS feed refresh, bounded background downloads, restart recovery, downloaded episodes stream like any other song
A real jukebox backed by mpv over its JSON IPC socket — server-side playback, not a simulation; administratively unavailable (with a clear error) if mpv isn't installed
Both original Subsonic auth modes (token/salt and password, including enc: hex), verified against an AES-256-GCM-encrypted credential kept separate from the Argon2id hash used for native login — see docs/subsonic-compatibility.md
/rest/* authentication is entirely independent of the browser session/CSRF/external-auth flow

Quick start

go build -o vibesonic ./cmd/vibesonic
VIBESONIC_SESSION_SECRET=$(openssl rand -hex 32) ./vibesonic

Then open http://localhost:8080 — on a fresh database you'll land on the setup wizard, which creates the administrator account, your first music folder, and kicks off the first scan.

ffmpeg/ffprobe should be on PATH (or pointed to via VIBESONIC_FFMPEG_PATH/VIBESONIC_FFPROBE_PATH) for metadata reading, cover art extraction, and transcoding/HLS to work. mpv should be on PATH (or pointed to via VIBESONIC_MPV_PATH) for the jukebox to be available — without it, jukeboxControl returns a clear "unavailable" error rather than pretending to work.

Docker

docker compose up -d

See docker-compose.yml — mount your music directory read-only at /music and set VIBESONIC_SESSION_SECRET.

systemd

See systemd/vibesonic.service.

Configuration

VibeSonic is configured entirely through VIBESONIC_* environment variables — see docs/configuration.md for the full list and defaults. There is no separate config file.

Documentation

docs/architecture.md — how the pieces fit together
docs/configuration.md — every environment variable
docs/external-auth.md — trusted reverse-proxy authentication
docs/subsonic-compatibility.md — protocol endpoint status

Development

go fmt ./...
go vet ./...
go test ./...

Most tests exercise real SQLite databases and, where relevant, the real ffmpeg/ffprobe binaries (skipped automatically if not installed). No mocks are used for the database.
