Move your Spotify playlists and Liked Songs to TIDAL through a browser-only web app — no server, no install. It matches each track to TIDAL (ISRC first, with a smart fallback), lets you review and fix anything before writing, and keeps your playlist order intact. Everything runs in your browser and talks straight to Spotify and TIDAL; your tokens never leave your machine.
Use it now: sync.ignorethedark.com — a hosted build of this exact code, so you can sync without cloning or running anything. It's a static page: nothing is sent to or stored on a server; everything still happens in your browser.
Connect both accounts with your own API credentials:
Browse your Spotify playlists and Liked Songs alongside your TIDAL library, and pick what to sync:
Review the matches before anything is written — resolve unmatched tracks, handle duplicates, and choose options like preserving order in Favorites:
Then sync, keeping your exact Spotify order:
Requirements: Node.js ≥ 22 and pnpm (to run/build), plus your own developer apps for Spotify and TIDAL.
The app uses the Authorization Code + PKCE flow, so register both as public clients — no client secret is needed. Set the redirect URI on each app to the URL where the app runs:
- Local dev:
http://127.0.0.1:5173/ - If you deploy it: your site's origin, e.g.
https://your-app.example/
Then run:
pnpm install
pnpm devThis opens the app at http://127.0.0.1:5173. Paste each service's Client ID to connect, pick what to sync and where, review the matches, and confirm.
- ISRC-first matching with a fuzzy title/artist/duration fallback.
- Review before writing — resolve unmatched tracks by picking a suggestion or pasting a TIDAL link; nothing is written until you confirm.
- Order preserved — new playlists mirror the Spotify order exactly.
- Flexible destinations — a new TIDAL playlist, an existing one (append-only), or your TIDAL Favorites.
- Duplicate handling, live progress, a match cache for fast re-runs, and a "last synced" badge per playlist.
Everything stays in your browser's localStorage — your client IDs, OAuth tokens, and sync history. There is no server and no database; the app only ever talks to Spotify and TIDAL directly. Clearing your browser data (or using the in-app controls) removes it.
