Open-source Microsoft To 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.

Planify is a desktop task manager designed for GNOME and built with GTK4 and libadwaita. It helps people capture to-dos, group them into projects and sections, and keep a plan for the day, while keeping the data in sync with services they may already use.

Tasks can be organized by drag and drop, tagged with labels, filtered, searched and given attachments or links. It supports several reminders per task, recurring schedules, a calendar view of upcoming work, progress indicators and a productivity overview, with an offline mode that syncs once a connection returns.

Synchronization options include Todoist, Nextcloud and CalDAV servers, which allows a self-hosted setup for people who want their data to stay private. The project states that it is not affiliated with or supported by Doist. Planify is written in Vala, released under GPL-3.0, and requires a Linux distribution with GTK4.

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.

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.

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.

Jotty is a self-hosted application for managing personal checklists and notes. It is easy to deploy, keeps all data on your own server, and can encrypt and decrypt notes for extra privacy. It was previously known as rwMarkable and is released under the AGPL-3.0 license.

The interface offers task lists with drag-and-drop ordering, a rich text editor for notes, keyboard shortcuts, translations, and custom themes and emojis. Data is stored as files rather than in a database, which keeps backups simple. For access control it supports single sign-on through OIDC and multi-factor authentication, and it exposes an API.

Docker Compose is the recommended way to install it, and the documentation covers initial setup, data storage, the versioning scheme, and encryption. Jotty suits homelab users and individuals who want a simple, private alternative to cloud to-do and note apps.

Manage My Damn Life (MMDL) is a self-hosted front end for managing CalDAV tasks and calendars. It is a web app, built with Next.js, that talks to your existing CalDAV server, so your tasks and events stay on the server you already run. The project is in beta, so caution is advised with production data.

It supports subtasks and many task fields such as due date, status, description and recurrence, calendar event management, multiple CalDAV accounts and multiple user accounts. Tasks can be viewed as a list, in a Gantt view or on a calendar, and you can create task filters to see them as you prefer. It has OAuth support for CalDAV accounts, with Google Calendar supported, and a desktop-first, somewhat responsive layout. Planned features include full RFC 5545 field support, drag and drop, customizable views and plugins.

MMDL has been tested with Nextcloud, Radicale and Baikal and should work with servers supported by the tsdav library. It is licensed under GPL-3.0 and uses Weblate for translations.

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.
