Stacer

Stacer is an open source system optimizer and application monitor that helps users to manage the entire system with different aspects, it's an all-in-one system utility. In the Startup Apps tab, you can view the applications the system launches at boot time and set up new startup apps. This is especially handy if you work with different distributions: You do not always need to think about where you need to set up applications that run at boot time on the respective systems, and you can also tell Stacer to lock an application for the next start as a test, without having to plumb the depths of the Control Panel. This is where you can remove unnecessary log or cache files and empty the trash can on your system. In the initial state, Stacer does not provide any data for trash disposal; you first need to enable the desired categories and then launch a system scan.
