Linux distributions are widely used as server operating systems due to their security and reliability. Being in general not really popular for desktops, various Linux flavors are still used by freelancers and office employees on their personal computers.

To control personal or team’s time expenses and measure productivity, various Linux compatible timekeeping solutions are available. Many of them are free and open-source, which is a plus. The bad thing about Linux-based time-trackers is that mostly they are buggy and require additional effort when installing and configuring them. But we did some research and found time-tracking software for Linux operating systems that is easy to install and use.
