Tundra is an open-source MyAnimeList scrobbler application for Linux. It automatically detects media players running on your computer, checks for any anime videos playing, and marks them as watched on your MAL profile.See on GitHub
Tundra is open-source, which means that anyone can look at its source code to look how it is working internally, make it better, and share their improvements with everyone.
The application itself is very lightweight and is almost non-existent to your system resources. It can run either with a graphical interface, or as a daemon in the background, so it's invisible during your normal work.
