Stacer – Simplest way to optimize and cleanup Linux OS

Stacer is a free system maintenance utility for Linux


Those days are gone when Linux used to be always command line mode. In the recent past there has been a surge in the number of GUI based applications for Linux that are intuitive to use and offer functionality closer to what can be done from command line via Terminal. One such tool is ‘Stacer’.

Stacer Linux Optimizer Features

Stacer is a completely free and one-stop system optimizer you have been waiting for. Its powerful features are easy to use in a nice looking user interface. The application is readily packaged as .deb and .rpm binaries, which can be used right away for installing it in Ubuntu, Linux Mint, elementary OS, Fedora & derivatives, and etc..It is also available in AppImage format for use in any Linux distributions.

Download Stacer

Download Stacer

Ubuntu, Linux Mint, and elementary OS users can download .deb file which get installed by double-clicking on the installer.

Fedora and derivatives need to download .rpm binaries which also installs right away.

Other Linux distro users can try the .AppImage format. This is a format which is similar to portable apps for Windows. Give executable rights to the downloaded .AppImage file, and you are ready to go! To give executable rights, simply right-click on the file and go to “Properties”. In the “Permissions”, check the box that says “Allow executing file as program”, and click OK. After that you can double-click on the file to run it.

Here is the glance at each of the features which Stacer can do for you, just by click!

1Dashboard – System Info

Stacer Dashboard

Dashboard displays system resources usage including CPU, RAM, and Hard disk space. It also displays system info and network bandwidth statistics for the session. Also handy to see Linux kernel version listed there!

2System Startup Applications

Startup Applications Manager

System Start Apps tab lets you manage the existing startup apps, and also add new startup entries if needed.

3System Cleaner

System Cleaner

This is my favorite part of this tool – System Cleaner. If you have been a Windows user, you might be aware of Ccleaner.  Similar to Ccleaner, Stacer also has powerful features that are enough for most of end users. It gets rid of Package Caches, which can occupy significant amount of Hard disk space over a period of time. Additionally, it cleans Crash Reports, Application Logs, Application Caches, and also empties Trash for you.

4System Services

System Services

System Services tab lets you manage currently running system processes. You can start/stop system process if needed in case of troubleshooting your PC. I advice caution while managing system services, especially for new Linux users. I recommend not to use this tab unless you know what you are doing. Turning off important system processes can cause adverse effects to your system.


Manage Running Processes

This feature is similar to “Task Manager” in Windows. You can view running processes and view amount of system resources consumed by each process. You can also kill a process by selecting it and then clicking on “End Process” button.


Stacer’s Uninstaller

You also get a Uninstaller in this program. The downside is you will see tinest system apps and apps that you installed to. I would recommend to use the search functionality so that you don’t have to scroll through thousands of little apps installed in your computer.

7System Resources

Resources Usage History

System Resources tab comes in handy when you want to take a look at summary and historical usage statistics of CPU, Memory, and Network.

That’s it! Hope you enjoy using Stacer for optimizing your system. Do let us know your feedback in comments below.
