Is TimeTagger actively maintained?
TimeTagger logged 24 commits over the last 11 months, but none in the most recent quarter. Development has paused rather than stopped outright — worth watching before a production deployment.
The most recent tagged release, v26.1.3, is about 8 months old.
TimeTagger ranks #12 of 13 tracked time tracking projects. Several better-maintained options exist in the same category — they are listed below.
What TimeTagger actually does
TimeTagger is an open-source time tracking tool designed around an interactive timeline interface and detailed reporting capabilities. It allows you to record, categorise and analyse your working hours through a self-hosted web application. The codebase is written in Python and is distributed under the GNU General Public License v3.0.
Best fit: This is a suitable option if you want a self-hosted time-tracking utility with a focus on timeline visualization rather than complex billing workflows.
Worth knowing: The repository exhibits low maintenance activity and an at-risk health score, meaning you may encounter unpatched bugs or need to maintain the codebase yourself if issues arise.
Deployment notes
As a Python application, you will typically need to run it behind a reverse proxy to handle TLS termination and configure persistent storage for your time-tracking database.
