Features & Capabilities

Flatline is a useful Chrome extension that streamlines the installation of Flatpak applications via popular software portals like Flathub, apps.gnome.org, and appcenter.elementary.io. By integrating with these platforms using AppStream technology, Flatline allows users to open GNOME Software or any Flatpak-compatible software center directly to an app's detail page with a simple click. This tool requires Flatpak, a Flatpak repository such as Flathub, and GNOME Software or a similar flatpak-supporting center installed on your system.

With Flatline, users enjoy a seamless experience managing Flatpak apps without manual searches or commands, enhancing ease of installation and app management for Linux users who prefer graphical interfaces.

Is Flatline Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Flatline requires very minimum permissions.

Risk impact analysis details

High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.
Low ******* ****** ** *** ********* ******** ************ ********** *************

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Flatline may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
