syncify

Transfer your music library between streaming services.

What it does

syncify reads your playlists and liked songs from one streaming service (currently Spotify) and recreates them on another (currently TIDAL). It matches tracks by name, artist, and album, previews matches before transferring, and creates playlists on the destination service.

Features

• OAuth-based login to Spotify and TIDAL
• Reads playlists and liked songs from Spotify
• Fuzzy track matching across services
• Preview matched/unmatched tracks before transferring
• Creates playlists and adds tracks on TIDAL
• Invite-gated access with email approval flow
• Rate limiting and abuse prevention
