About Liner

What is Liner?

Liner is a spatial canvas for organizing music. Think of it as a whiteboard where every sticky note is a song. You can drag audio files from your computer, paste links from Spotify, SoundCloud, or Apple Music, and arrange them freely on an infinite canvas.

Group songs into frames for albums, EPs, or mood boards. Add notes for production ideas. Play tracks directly from the canvas. Export the final tracklist when it's ready. Liner supports WAV, MP3, FLAC, and AIFF files alongside links from major streaming services. It is designed for the way musicians actually think about their work — spatially, not in rows and columns.

Why we built it

Every album starts with a pile of ideas. Demos on a desktop. Voice memos on a phone. Spotify links in a group chat. Spreadsheets that try to make sense of it all.

We wanted a tool that feels like pinning tracks to a wall — where you can step back and see the shape of a record. Where sequencing is a drag, not a formula. Where files stay on the machine and the creative process stays private.

Local-first by design

Audio files never leave the device. Liner stores everything locally using IndexedDB and the File System Access API. Cloud sync for metadata (song titles, positions, notes) is available as an opt-in — but never required. No account needed to start. No data harvesting. The music stays local.

The team

Liner is built by ninetynine.digital, a small studio focused on tools for creative people. We make software that respects privacy, simplicity, and good taste.

Technology

Liner is built with Next.js, a custom HTML canvas engine, Zustand for state management, and Clerk for authentication. Cloud sync uses Convex for real-time data. Payments are handled by Stripe. The app is hosted on Vercel.
