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


I use linkding for bookmarks and readeck for read-it-later
linkding now support offline snapshot and also has a reader mode. What does readeck bring to the table?
I prefer to keep the two separate. My linkding is used to dump pages I may revisit someday or not where readeck is stuff I want to definitely revisit.
As far as features go, the big one for me is that Readeck can export to epub. I don’t use it a ton, but it’s nice to be able to load an article on my ereader.
