Stacer is an open source system optimizer and application monitor for Linux. It’s an all-in-one program that will allow you to enable/disable startup applications, provides a system cleaner similar to BleachBit, a system search, enable/disable system services that are running on boot and/or running right now, a process manager, package uninstaller and a heads up display of your resources.
Can you already perform/check everything that Stacer offers out of the box either from the command-line or the built-in graphical tools? Of course you can. Stacer is just a nice all-in-one solution.
Stacer is available for Debian, Fedora, Arch/Manjaro users can find it in AUR, as a PPA or you can build it from source. For more info check out the official project page on github.
