How the time tracking tools compare
Ever Gauzy and solidtime tie at 96/100. ActivityWatch has the largest following at 19k stars, yet ranks #6 of 13, held back mostly by Docker support (no Docker image).
The most recent release is Ever Gauzy v111.142.11, published yesterday. None of the measured options scores under 40. By stack, Go (2), Python (2) and Nodejs (1) are the most common. ActivityWatch, Beaver Habit Tracker and Focus Flow are permissively licensed; Ever Gauzy, solidtime, Wakapi and 6 more are copyleft. Virtual TimeClock is source-available rather than open source, which limits commercial reuse. Virtual TimeClock is not hosted on a forge Repoly can read, so it has no measured score yet.
