Habitica

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.
