There are so many out there, a few that I came across include:
- Wallabag ( GitHub, Website): Older, long history, somewhat clunky now?
 - LinkWarden (Website): Focus on multi user and teams?
 - Raindrop.io (Website)
 - Omnivore (Website)
 - Hoarder (GitHub)
 - Shiori (Article)
 - Readeck (Website)
 
Having a giant comparison table for this might be nice


Similar here. As I don’t need multi-user support, I don’t bother with self-hosting some tool.
Bookmarks go to Safari where they’re synced between all my Apple devices and pop up automatically in the address bar.
And long-term bookmarks (news articles, references, etc.) go into Anybox which keeps an offline copy of the website so I can still read it in 10-20 years.
