After quite some exploring around and struggles I made my peace with https://raindrop.io. Am I happy with that? Of course not. But that's the only hosted one which has extensions and apps for almost every browser and OS I use. I wish there a functional open source service (hosted) with wide range of platforms support that I could pay for and use.

I've been using Karakeep (formerly Hoarder) for a few months. So far, I like it. I particularly like having an iOS app so sharing new bookmarks from different apps is really easy. Instead of pulling from the browser, it retrieves its own copy with a headless Chrome, so if you need a login, the snapshot breaks. But, overall, I've been pretty happy.

But, I'll definitely check out Omnom too!
