What TimeTracker actually does
TimeTracker is an open-source application designed to monitor hours spent on various clients and projects. It includes built-in timers, kanban task management, customer relationship management, expense tracking, and multi-currency invoicing with PDF and e-invoicing support. Additionally, it offers reporting tools, OIDC single sign-on, and a REST API for integration.
Best fit: Freelancers and small teams who need an all-in-one platform to handle project time management, client invoicing, and basic CRM tasks in a single self-hosted tool.
Worth knowing: The moderate maintenance health score indicates you should evaluate whether the community and update frequency align with your long-term reliability requirements.
Deployment notes
Because it is packaged for Docker, you will typically need to configure persistent volumes for your data and place it behind a reverse proxy to handle TLS termination.
