Plan the day in the morning, capture tasks in your own words as they appear, and let every device settle on the same list by evening: that rhythm is what OpenTodo is built around. The Today view opens with a briefing, a daily limit, and morning, afternoon, and evening sections, with time blocking and meetings counted against the day's real capacity. Quick add understands natural language in six languages, a pasted list becomes tasks in one step, and the command bar, inbox processing, email-to-task, and dictation keep capture fast. Projects organize work with sections, boards whose cards carry notes, timelines, sub-projects, and areas, while recurring tasks and sequential projects handle routines and ordered work. Lists can be shared with the people you live and work with, invited by link once the owner account exists. Every device keeps a full copy and works offline; changes are stamped per field and merge cleanly through your server when you reconnect, with history and undo preserving earlier values. CalDAV and calendar feeds connect your calendars, GitHub and GitLab issues flow in, and webhooks plus ntfy, Pushover, and Gotify send notifications out. Scheduled backups go to a folder, S3-compatible storage, or WebDAV, and the whole server is one container around one SQLite file. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
