    Why OpenTodo

    The comfort of a commercial app.
    The freedom of software you run.

    Local-first, for real

    Every device keeps a full copy of your tasks. The app opens instantly, works on a plane, and syncs the moment it sees your server again.

    Keyboard-first

    Capture, triage and finish without touching the mouse. Try the keys below.

    Your data, one folder

    A single SQLite file in one volume. Back it up and you have backed up everything. JSON export any time.

    Tiny footprint

    One distroless container, no database server, no Redis. Happy on a Raspberry Pi or the cheapest VPS.

    Private by design

    The app makes no requests except to your server. No telemetry, no crash reporters, no third-party fonts.

    An API that's a first-class citizen

    REST endpoints and API tokens write through the same op log as the app. Create a task with curl and watch it land on your phone on the next sync.

    # add a task from a script
curl -X POST $OPENTODO/api/v1/tasks \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"title":"Renew passport","priority":1}'

    Built in the open, with specs

    Every feature starts as an OpenSpec change. Behavior is written down before it is built, so you can read exactly how it works.

    Sync that just converges

    Edit anywhere. Offline.
    Never pick a version again.

    Every change is a tiny operation on one field, stamped with a hybrid logical clock. Devices queue them while offline and exchange them when they reconnect. The same rule runs everywhere, so every device lands on the same state. Play with it:

    Toggle Wi-Fi on a device, change something, then reconnect.

        Tip: click a task title to rename it, click the circle to complete it.

        What you get today

        Everything a task app needs.
        Nothing that phones home.

        At home on a phone

        The same app, the same offline copy of your data. The detail panel slides over the list; the sidebar tucks behind a menu. No app store, no account on anyone else's server.

        • Owner account on first visit, sign-up closed afterwards
        • Sessions on every device, API tokens for scripts
        • Projects, Inbox, Today, Upcoming, Completed
        • Priorities, floating due dates with optional time, notes

        What's next

        v0.1 is the walking skeleton.
        The rest is already written down.

        Every planned feature exists as an OpenSpec change: a proposal, behaviour specs with testable scenarios, a design and a task list, all validated before a line of code is written. 35 changes are specified and waiting to be built. Click any item to read exactly how it will behave.
