ActivityWatch

The best free and open-source automated time tracker.·activitywatch.net

ActivityWatch is a free, open-source, automated time tracker that runs on a user's computer and monitors which applications and websites are used. It works on Windows, macOS, Linux, and Android, with browser extensions for Chrome and Firefox to track web activity. All tracked data is stored locally on the device rather than uploaded to the cloud, and the software can be extended with watchers, importers, and custom visualizations.
