AppImages are portable Linux applications packaged in a single file that you can download and run without installation. Unlike DEB or RPM packages, they don't require root access or system-level changes. You just make the file executable and double-click to run.

But here's the catch. AppImages don't actually install on your system in the traditional sense. They exist as standalone executables that you have to manage manually. There's no automatic desktop integration, no system menu entries, and no built-in update mechanism.

This way, you are stuck manually making files executable, going through folders to launch apps, and checking for updates yourself.

That is where AppManager comes in. This is a tool that handles all that tedious legwork for you.
