Open-source Any.do alternatives

Super Productivity is a to-do list application that adds timeboxing and time tracking to everyday task planning. Tasks can be organized with sub-tasks, projects and color-coded tags, and viewed in a planner with a schedule timeline next to calendar events. Visual boards, including Kanban and Eisenhower Matrix layouts, help you sort work. It is written in TypeScript, released under the MIT license and tagged as local-first and privacy-friendly.

Time tracking produces time sheets and work summaries that can be exported to a company's tracking system. Habit tools include break reminders, an anti-procrastination feature and a focus mode with Pomodoro, Flowtime and countdown sessions, plus personal metrics. Integrations include Jira, Trello, GitHub, GitLab, Gitea and Linear, plus ClickUp, Redmine and Azure DevOps, importing assigned tasks and creating work logs automatically. It is available as a web app and as apps for Windows, macOS, Linux, Android and iOS.

Habitica is an open-source habit-building app that turns personal goals and daily tasks into a role-playing game. Completing tasks earns experience and gold, while missed ones cost health points, which gives everyday routines a built-in reward and penalty loop. It is aimed at people who find plain to-do lists dull and respond better to game mechanics.

Players level up a character, collect weapons and armor, and spend the gold they earn on in-game gear. The web application is a JavaScript project built on Node.js and Express with a MongoDB database and a Vue front end, and the same service is reachable through separate Android and iOS apps maintained in their own repositories.

The source code is publicly visible under a custom license described in the repository rather than a standard SPDX license. The maintainers have paused outside code contributions and do not accept AI-generated code, but the codebase stays open. Developers who want a local copy can follow the project's wiki guide for setting up Habitica locally.

Taskwarrior is a utility for managing task lists from the command line. It is developed as a portable open-source project, and it is surrounded by an ecosystem of tools, hooks and extensions that adapt it to different workflows. Repository topics place it in the to-do list and GTD space.

It is packaged for a wide range of Linux and Unix systems, macOS and Windows, with packages tracked on Repology, and it can also be built from source. The project website holds the online documentation, downloads and news, while the GitHub discussions forum is the recommended place for questions. Contributions of all kinds are welcome, including code patches, ideas, bug reports and discussion.

Taskwarrior is written in C++ and released under the MIT licence. It has been developed since 2006, mostly by a small group of volunteers, and the maintainers invite users to sponsor the project through GitHub Sponsors so that core developers can devote more hours.

Tasks is an open-source task and to-do app for Android. It is based on the source code of Astrid, a cross-platform productivity service that was acquired and discontinued in 2013, and the project revives that app as a maintained codebase. It is licensed under GPL-3.0 and its end-user documentation lives on tasks.org.

Beyond the Android app, the project offers an alpha desktop version, and Pebble watch apps are available through the Rebble and Repebble stores. It is written in Kotlin and uses Compose Multiplatform. Release builds are distributed through Google Play, as APKs on GitHub Releases, as a macOS zip and through a Linux apt repository, with published signing fingerprints for verification.

Donetick is an open-source app for organizing tasks and chores, either alone or together with family and friends. Groups can be created so that tasks are shared or assigned between members, which makes it popular for households. It is built with Go and React, ships a Docker image, and is released under the AGPL-3.0 license.

Tasks can be created in plain English: the app extracts dates, times, and recurrence from phrases such as every six months or every Monday and Tuesday at a set time. Scheduling is flexible, with daily, weekly, monthly, and yearly patterns, specific months or weekdays, and adaptive scheduling that learns from past completions. Recurrence can be based on the due date or on the actual completion date.

Other features include assignee rotation by fewest completed tasks, random choice, or round-robin, time tracking with session insights, and subtasks with smart reset. It suits families, roommates, and small teams who want a private, self-hosted way to share recurring responsibilities.

TaskTrove is a modern to-do manager that you host yourself. The project stresses privacy: it runs on your infrastructure with no tracking or data collection. Tasks can be created in natural language, for example by typing a phrase like tomorrow at 2pm, and can have unlimited subtasks, priorities, due dates, comments and file attachments. It is aimed at individuals and small groups who want a capable task app without a hosted account.

Recurring tasks can follow daily, weekly, monthly or custom patterns with automatic scheduling. Tasks can be grouped into projects with sections and color-coded labels, and viewed as a list, a kanban board or a calendar. The interface has light and dark themes, is mobile friendly and offers keyboard shortcuts such as a quick-add key and a search key.

Data is stored in JSON files, which makes backups and transfers simple. The recommended installation is Docker, with Docker Compose and manual setup also described. TaskTrove is built with TypeScript and React, and the repository metadata lists the license as Other, so check the license file for terms.
