An open source time-tracker based on an interactive timeline and powerful reporting.
TimeTagger is an open-source time tracking project, with 1.8k GitHub stars and a health score of 41/100. It committed 24 times in the last twelve months across 6 of those months, and its status is slowing down. Licence: GPL-3.0. It does not currently meet the momentum threshold, so verify maintenance before depending on it.

Health score combines commit recency, twelve-month commit volume, months with activity, release recency and archive state. Metadata refreshed August 2026.

This matters most when you plan to sell a hosted version. A permissive licence means anyone — including a competitor with more capital — can do the same, so your defensibility has to come from distribution, support or data, not from the code.
TimeTagger is not currently shipping at a healthy pace. Popular but stalled projects inflate how competitive a category looks — and they are also risky to build on.
The clearest opening in the dataset. Low open-source competition usually means either a genuinely underserved need or a market too small to attract volunteers — validate demand before assuming the former.
