Open-source OmniFocus 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.

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.

Tududi is an open-source system for organizing personal and work tasks in a hierarchy. Tasks belong to projects, projects can be grouped into areas, and notes and tags can be attached across the structure, which suits people who follow a getting-things-done style of planning. It is released under the MIT license.

Tasks can be filtered into views such as Today, Upcoming, and Someday and sorted by name, due date, creation date, or priority. It supports subtasks with progress tracking and a recurring-task system with daily, weekly, and monthly patterns, including monthly on specific weekdays. A Telegram integration lets you capture and manage items from chat, and your data stays under your control when self-hosted.

The application is built with React and Node.js with Express, and you can run it on your own server or buy a hosted subscription from the maintainer for a managed setup. It suits individuals and small teams who want a calm, privacy-minded alternative to hosted to-do and project apps.
