Someone bought me a coffee
This week, for the first time, a person I have never met sent a few euros to OpenTodo through the support page. It is one coffee. It also changed how the project feels to me. A thank-you note.
Free and open source · AGPL-3.0
Three things matter today. Two tasks are late, Monday is already full, and Mia answered your question about the trip.
That's how Today starts in OpenTodo: one sentence on what stands out, worked out on your device.
OpenTodo is a calm task list that runs on your own server. Plan your day, keep projects in order and share lists with the people you live and work with.
01
Your day, your projects, one quiet screen.
- Today, Upcoming
Today says what matters
One sentence under the date names what is late, what is full and who replied, and each part opens what it names. Your device works it out, offline, with no AI.
- Everywhere
Type it the way you say it
“Book the plumber friday 10am #Home p1” becomes a task with its date, project and priority, in six languages.
- Projects
Projects as a list, a board or a timeline
Sections, deadlines and progress at a glance. Share a project and assign its tasks to the people in it.
02
Everything included.
54 features in 6 groups, and the integrations you already use. Nothing is held back for a paid plan.
No tiers Every feature, for everyone. All features, with their docs

Yours, for good.
No OpenTodo account and no OpenTodo cloud. One server for everyone you share lists with, and you can leave with everything whenever you like.
- What it costs: Free, all of it
Free, all of it
No tiers, no seats, no trial: every feature for everyone on your server, the whole household included.
- Self-hosting: On your server
On your server
One container and one folder of data. A Raspberry Pi or the smallest rented server is enough.
- Offline and sync: Works offline
Works offline
Every device keeps a full copy. Edit on the train; changes merge field by field when you are back.
- Encryption: Encrypted if you want
Encrypted if you want
With end-to-end encryption, task text is encrypted on your devices before it reaches the server.
- How it works: AI on your terms
AI on your terms
Off unless you turn it on. Your model, local ones too; the assistant proposes changes you approve, and every change can be undone. Your own AI tools connect through MCP or the Claude Code plugin under an agent token.

Three ways in.
OpenTodo is not offered as a hosted service, so there is nothing to sign up for here. Move between the three later; your data comes with you.

News, releases and how it's built
The road to 1.0
Six releases between now and OpenTodo 1.0, what each one is for, and the promises that do not change on the way.
OpenTodo is coming to Google Play, and I need 12 testers
The Android app is in Google's review for the Play Store. Before it can be published, twelve people need to test it for fourteen days. Here is how to be one of them.
