Offline-first

Weigh anything against anything.

Kortlist is a tiny board for side-by-side comparisons. Score what matters, settle ties with a one-on-one tournament, and pass the whole thing along as a link — no servers, no sign-in, no fuss.

How sharing works

A whole board, inside the link.

No databases, no invites, no permissions. The URL is the document.

  1. 01

    Pack

    Your whole board — items, columns, scores — gets compressed straight into a URL on your device.

  2. 02

    Send

    Drop the link in any chat, doc, email, or DM. There's no backend in the loop. Nothing to spin up.

  3. 03

    Open

    Whoever opens it gets a fresh local clone. They can edit, score, and share again — independent forever.

What you get

Small enough to live on your device.

Six things that make Kortlist different from every other comparison tool you've tried.

  • All local, always

    Boards live in IndexedDB on your device. The app works on a plane, on the metro, in a tunnel.

  • Scores that count

    Thumbs up and down on every cell. The board adds them up so the winner emerges from the data.

  • Pairwise PlayCompare

    When the table can't decide, run a tournament. Pick a winner per matchup and let scores accumulate.

  • A whole board, in a link

    lz-string compresses the project into URL params. Your friends open it, no account, no sync.

  • Installable, anywhere

    Add Kortlist to your home screen on iOS, Android, macOS, Windows. It's a real PWA.

  • Tiny. Fast. Free.

    No backend means no costs and no telemetry. Open source, English-only, opinionated by design.
