Why not Keepass on a webdav server? Both Keepass on the computer and Keepass2Android can open the file directly. If you save it on one it will merge the changes in any other copies you have open.

I use shaarli https://github.com/shaarli/Shaarli It doesn’t sync with the browser but there is an android app for quickly storing links.

Honestly, those decades of solutions are useless unless they have both a version number and a date associated with them. And if that date is more that 6 months ago, it’s probably still useless even if it has both.
