Open Source Habit Trackers

Habitica is an open-source productivity platform that applies role-playing game mechanics to personal task management. By tracking habits, daily goals, and to-do lists, the system translates completed tasks into character progression, experience points, and virtual rewards. The platform supports collaborative productivity by allowing users to join parties and complete group quests alongside their individual responsibilities. It is designed for self-hosting, providing users with full control over their data and system configuration through a structured relational database and a standardized application programming interface. The system includes built-in traffic management tools, such as request throttling and client identification, to maintain stability and monitor usage patterns. Developers can coordinate complex server and database components within local environments to facilitate testing and feature development.

uHabits is a habit tracking application and behavioral progress tracker designed to monitor daily routines and build long-term consistency. It utilizes mathematical decay formulas to calculate habit strength, rewarding consistent activity while limiting the impact of occasional misses. The system includes a customizable scheduling engine that defines repetition patterns for recurring goals, supporting both simple daily and complex weekly intervals. Users can interact with their data via a home screen widget dashboard, allowing them to monitor status and mark tasks complete without opening the application. The application provides task reminder automation with notifications that allow for direct activity completion. It also features a data export utility that serializes tracking history into structured text formats for external analysis in spreadsheets or databases.

AFFiNE is a collaborative knowledge base and productivity suite designed as a private-first, local-first platform. It provides an integrated workspace that combines structured documents with an infinite digital canvas, allowing users to organize complex information through a block-based model. By prioritizing local data persistence, the platform ensures immediate responsiveness and data sovereignty while maintaining a distributed state for real-time synchronization across multiple devices. The platform distinguishes itself through a canvas-integrated database engine that enables transitions between free-form whiteboarding and structured tabular views. It utilizes conflict-free replicated data types to manage concurrent edits, ensuring consistent collaboration. Users can extend the workspace with modular artificial intelligence integrations, which use natural language prompts to generate, summarize, and transform content into various visual or structured formats. The software is built for self-hosting, allowing teams to maintain full control over their data and infrastructure. It supports container-orchestrated deployment, providing tools for managing private workspaces, authentication, and production-ready environments. The system is designed to be installed and configured on personal or team-managed infrastructure, ensuring that all sensitive information remains within a private, secure, and scalable environment.

Kanboard is a self-hosted Kanban project management tool and productivity suite designed for tracking software tasks and team collaboration. It provides a visual system for managing workflows through the use of boards, columns, and cards. The project features an extensible plugin framework and a comprehensive API for programmatic task and project administration. It includes specialized identity management through LDAP integration, allowing for the synchronization of user accounts and group permissions from directory servers. The system covers a wide range of capabilities, including event-driven workflow automation, detailed project analytics such as burn-down charts and cycle time measurement, and granular role-based access control. It also supports integrated time tracking, subtask decomposition, and multi-method authentication including two-factor authentication and reverse proxy support. The application is compatible with MySQL and PostgreSQL for persistent data storage and can be deployed using Docker Compose.

Planify is a task management application and productivity suite designed for organizing to-do lists and schedules. It functions as a desktop tool for personal task management, featuring a visual calendar for planning deadlines and tracking daily productivity. The project integrates cloud synchronization to maintain data consistency across multiple devices. It also includes a natural language interface that acts as a documentation assistant, utilizing an API to retrieve answers and excerpts from technical content. The application covers a broad range of organizational capabilities, including task workflow management through labels and projects, automated recurring task scheduling, and a reminder system for deadlines. It further provides productivity trend analysis and the ability to attach external resources and web addresses to specific tasks.
