I'm also looking into this a bit as I'm ditching Nextcloud and need a more modulare approach to managing the three things i care about: calendards, files and bookmarks. Sorted calendars with Radicale (superb) and files with Syncthing but now looking at the bookmarks. This (https://github.com/awesome-selfhosted/awesome-selfhosted?tab=readme-ov-file#bookmarks-and-link-sharing) has several solutions proposed. lingding and linkwarden seem to be good and reasonable active on Github. Anyone compared these?
I have tested both lingding and linkwarden. Lingding was easy to use and did the basics in bookmark management. Though I settled on linkwarden for its saving of webpages in different formats with folder and subfolder organisation in the UI.
Both are good options, but linkwarden seem to be more power user focused.
