Frequently asked questions

How many open source time-tracker projects are there?

This registry tracks 8 projects tagged time-tracker, with 42,888 GitHub stars between them. The most-adopted is ActivityWatch at 18,919 stars.

Are these time-tracker projects free to use?

Yes — 8 of the 8 carry an explicit open-source licence across 3 distinct licences, so there is no licence fee. Where a project also sells a hosted or enterprise version, the self-hosted path remains free.

Which time-tracker project should I choose?

The list above is ranked by GitHub stars, but stars measure attention rather than fit. Check three things on each card: the licence (permissive versus copyleft), the language it is written in, and the last-push date — a high-star project that has not been pushed in a year is a liability.

Are these time-tracker projects still maintained?

6 of the 8 were pushed in the last 90 days, and every card shows its exact last-push date so you can see the rest. Sort your shortlist by that date before committing to a migration.
