Tangram for Linux is a Browser Built for Web Apps
For an ordered way to use your favourite web apps on Linux check out Tangram, a GTK-based web browser.
Oh, I know what you’re going to say: “Dude, I already have a web browser” — and for most people a regular web browser (like Firefox, Chrome, etc) is a solid way to use web apps on Linux desktops.
But what if you want to keep your web apps separate apps from the rest of your browsing?
Enter Tangram, an open-source GTK4/libadwaita app powered by the the same Webkit engine as GNOME Web (aka Epiphany). As such, pretty much all modern web content works in it.
