📖Max the AppCenter Out

Empty App Center may be confusing

After a fresh elementary OS installation, you may be confused with a very poor AppCenter.

Though elementary OS (since 5.1 version) comes with Flatpak support out of the box, you need to complete some actions for non-curated apps to add them to the AppCenter.

1. Head to Flathub, and click the Install button to install at least one app you need.

Install from Flathub first

2. Open the downloaded .flatpakref file with Sideload, and complete the app installation.

3. Reboot (just in case).

Since just one app from a remote like Flathub is installed, all other apps from that remote will be also automatically shown up in the AppCenter.
