Synthseek

Self-hosted, multi-user music library automation.

Synthseek searches across music providers, downloads through your slskd instance, matches metadata, and organizes your personal library with Beets. It is multi-user, provider-agnostic, and ships a built-in MCP server so assistants can drive your library.

Features

• Modern, responsive web UI (mobile and desktop friendly)
• Multi-user: local accounts and Plex OAuth, with member management and per-user libraries
• Provider-agnostic catalog (Deezer by default, no API keys required)
• Search for tracks, albums, artists, and playlists
• slskd integration for P2P downloads, with an automatic or optional yt-dlp fallback
• Per-request download-source and quality selection
• Spotify library import, and playlist import and export (JSPF, XSPF, CSV)
• Discovery integrations with Last.fm and ListenBrainz
• Lidarr delegation with tag and monitor-scope selection
• Metadata matching
• Automatic file organization
• End-to-end playlist downloads with automatic Plex reconstruction
• Built-in MCP server, so assistants can search and manage your library
• Localization (more languages are on the way...)
• Real-time progress tracking, logs viewer, and in-app update notifications
