Habitica

Habitica is an open‑source habit‑building program that frames daily tasks, goals, and routines as elements of a role‑playing game. Users earn experience points and level up when they complete activities, while missed tasks reduce health points. The system also awards in‑game currency that can be spent on virtual equipment such as weapons and armor, providing a gamified feedback loop for personal productivity.

The application is designed for individuals who want a lightweight, self‑hostable solution for tracking habits and staying motivated through game mechanics. It offers a free tier without subscription requirements and is released under the GPL‑3.0 license, allowing anyone to run, modify, and share the software. The codebase includes a web interface and links to mobile clients for Android and iOS.

Developers can contribute to the project via its public repository, which provides documentation for setting up a local instance, guidelines for API usage, and resources for extending the platform. The community maintains a wiki and help resources, and bug reports are directed through a dedicated contact channel.
