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
Floccus is what I use for bookmarks.
Works across pretty much any browser and on Android (maybe iOS, I’m not sure). I’ve got it set up on my Synology NAS through webdav, and it’s been reliable.
I do also use Linkwarden, but that’s more to collect web pages, and not just bookmark them. The archive feature is great, since it doesn’t rely on the page still being live to work.
Linkwarden and Floccus are very different, IMO.
