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.
Open source · AGPL-3.0 · v0.1
Your tasks.
Your server.
An open-source, local-first task manager you host yourself. Everything you expect from a polished task app, without the subscription, the tracking or the lock‑in.
Go ahead, it works. Press q to add a task, j/k to move, c to complete.

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