Android browsers can already add pages to home screen but Hermit takes this even futher.
It has significantly better UX with frameless and full screen modes. You can bookmark pages, so on Lemmy you can quickly bookmark community in specific sorting order. There are user scripts and blockers and loads of customization. You can even add push notifications for changes on the site or RSS feed.
I’ve been running most Fediverse web apps through Hermit and it works really well! The only exception is that I couldn’t figure out how to setup notifications on Mastodon.
I mean there is no such thing as a free lunch. It has sandboxes, scripts, multi instances, website sync and other stuff. But, I agree most wouldn’t find much value in it. I frequent some websites quite a bit and some in rare cases. Managing them in Firefox and Samsung internet isn’t that seamless. Hermit is like a launcher for all my lite apps which I can launch when needed which is neat.
