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.

A personal to-do list that scales to team project management: Vikunja is an open-source task manager that grows with the work. Every project can be viewed four ways - classic list, drag-and-drop Kanban board, Gantt chart for timeline planning, and a spreadsheet-style table - so a project manager watches the Gantt while developers work the board, on the same data. Tasks carry the full attribute set: labels, priorities, due dates and reminders, recurring schedules, subtasks and task relations, file attachments, assignees, and comments, and Quick Add Magic parses natural-language input like dates and labels typed inline. Projects share with team members or via links, and saved filters slice tasks across projects. Built-in CalDAV support (VTODO) syncs tasks bidirectionally with clients like Thunderbird, DAVx5, and iOS Reminders, and one-click importers migrate from Todoist, Trello, and Microsoft To-Do. Nothing is metered - unlimited projects, tasks, filters, and attachments. A single Go binary with a Vue frontend runs against SQLite, MySQL, or PostgreSQL, exposes a full REST API, and works as an installable PWA on mobile. AGPLv3-licensed.

Tududi is a self-hosted planner that turns a pile of tasks into a plan for the day, keeping projects, notes, goals, and habits on a server you control. One Add box files an Inbox item, Task, Note, or Project and understands natural-language dates, recurrence, tags, projects, and people, so "every first monday #home" becomes a recurring task without opening a form. The Today page switches between planning mode, with a timeline or list beside your calendar and optional AI help to sketch the day, and doing mode, with a Next card and a hint when a free slot fits a small task. Tasks have subtasks and live in projects and areas, projects link to season or year goals, and saved views, project templates, and optional Eisenhower and Kanban boards organize the work. Habits support build or quit goals with streaks, a strength score, and a history grid, while notes offer linked pages, backlinks, and mermaid diagrams. Households and teams share projects with read-only or read-write access, assign tasks to people, and follow an Everyone board; members without email sign in through one-time links. Telegram captures tasks and can send daily summaries, CalDAV syncs with reminder apps, OIDC handles single sign-on, and an MCP server lets Claude or Cursor manage tasks. AI stays off until you enable it and add a provider; local models work too.

Pomodoist pairs a task manager with a Pomodoro timer, so the list of what to do and the clock that gets it done live in the same app. Type a task the way you would say it and the quick-add bar sets its priority and estimates its Pomodoros as you type, filing it into the Inbox, Today, or Upcoming views. Plan the week on a calendar, drag cards across a kanban board, spread work along a timeline, or sort it into a four-quadrant priority matrix when everything feels urgent. Start a focus session and the timer tracks intervals against the task at hand, with configurable work and break lengths, while a 3D desktop companion focuses, rests, and celebrates along with you. Share a project and the discussion stays beside the tasks, with comments on shared items and the team's focus time visible next to the work itself. Reports chart weekly focus time, completed tasks, and habit streaks, and voice notes can become task checklists when typing is not an option. An MCP endpoint lets your AI tools manage the same projects after an OAuth sign-in, and optional Google Calendar and Telegram integrations meet the planner where you already are. The self-hosted instance unlocks every feature locally, with your own accounts and one-command backups of the whole database.

Notes, tasks, and habits in one app, synced only to a server you run yourself. Notes are written in Markdown and render right in the list, so reading one costs no clicks. Tasks get a planned date and time, a duration, a checklist, and a timer. Weekly statistics show what got done and how long it took. Habits are measured by how overdue they are, not by an unbroken streak. A habit on a ten day interval that is two days late reads 120 percent. Charts track progress toward the target for today, this week, this month, this quarter, and this year. They also list the ten longest streaks and what you finish on each weekday. Categories and priorities span all three item types. Search reads note text and checklist items, not only titles. Filter by date, status, or how overdue a habit is, then sort with eleven keys. Pick from 26 themes in dark and light mode and 20 languages, with full keyboard and screen reader support. Import and export JSON, YAML, TSV, or Markdown, or bring in a Google Keep Takeout ZIP. Native apps for Windows, Linux, macOS, iOS, and Android sync with your server. The single-user Docker server also serves an OpenAPI spec, a Scalar UI, and a log page behind the same login.
