I'm also using Karakeep. It also has LLM-powered tagging, which, in my experience, works excellently. It's easy to self-host, fast on a relatively underpowered NAS, and I love the UX. Highly recommended.
Linkwarden looks nice, too, but when picking an option, I wanted one with a native Android app.
Bitter irony is that the one with the best iOS app is lacking a Safari extension, while the one with a mediocre iOS app already has a beta Safari extension.
