Just a heads-up. Found that a while ago and much prefer it over wallabag.
Thanks for sharing LinkAce! Maintainer here. If you or others have any questions, feel free to ask.
What makes it better?
I think it's primarily personal preference of features and how things are stored and presented. While Wallabag is more a Pocket/Read It Later alternative, LinkAce does not save the website itself, but a reference to it including the taxonomy you assign to it. It is intended to be a long-term bookmark archive, but without handling all the website archiving on its own.
Wallabag only stores links. ArchiveBox archives a snapshot of the actual content of a page at a specific point in time.
Wallabag extracts the content and stores it. Not just the links.
