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.

Vikunja is a task manager that you can host and control yourself. It covers to-do lists and broader project management, and exposes an API so it can be connected to other tools. Its backend is written in Go and the web front end in Vue. The tagline stresses ownership: a task manager whose data and hosting you decide.

The README mentions an optional hosted version for people who want a hassle-free setup for themselves or a team, and a Vikunja Pro tier that adds an admin panel, audit logs and time tracking. The maintainers also note that they use LLM-assisted coding tools in parts of the codebase. The repository has documentation, a roadmap and contribution guidelines.

Vikunja is licensed under AGPL-3.0. The community version is free to self-host, which suits individuals, families and small teams who want an open alternative to hosted to-do and project apps. Support comes from donations, sponsorship and paid hosting or Pro plans.

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.

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.
