Tangram is a browser for your pinned tabs. What this means is that I can put all my frequently visited websites in an app and have the ability to view them all with great ease. Before I was signing into everything each time I needed to check it but now I just switch to my workspace that has tangram open. I use mine for email, discord, and matrix. As a tab hoarder it’s also quite nice in how it clears up many of my tabs.
Never heard of them but quick research makes me think sorta. These all seem to be mobile apps but this is for linux desktop. It keeps all these sites in one app as opposed to just making a desktop shortcut.
Ik linux mint has a webapp manager preinstalled. If this is anything like webapps then neato.
