OpenTodo
Free and open source · AGPL-3.0
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
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.
“Book the plumber friday 10am #Home p1” becomes a task with its date, project and priority, in six languages.
02
54 features in 6 groups, and the integrations you already use. Nothing is held back for a paid plan.
No tiers, no seats, no trial: every feature for everyone on your server, the whole household included.
One container and one folder of data. A Raspberry Pi or the smallest rented server is enough.
Every device keeps a full copy. Edit on the train; changes merge field by field when you are back.
With end-to-end encryption, task text is encrypted on your devices before it reaches the server.
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.
04
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.
