While I love Karakeep, the truth is that I'm using it to solve this exact same problem, even though its project goals are not as well aligned. I would seriously consider giving Hister a try because it seems like a better fit. Bonus points for being written in Go.

I suppose the one thing I need would be an easy way to share links into Hister. Hopefully we will see both Android/iOS mobile apps to send links into Hister and better support for Safari. I wonder what could be possible with the extensions support available on mobile browsers too (Safari, MS Edge, Firefox).
