Going to check out Linkwarden since I really like the idea of being able to self-host something similar since Raindrop could one day disappear (#googlereaderneverforget).
A feature Raindrop has is it can export bookmarks to a standard xml file, which I then have a script that automatically adds them to Archivebox[2] for a local copy and to add them to archive.org[3].
Does Linkwarden, have a feature to automatically submit a bookmark to archive.org along with the local copy? That would greatly reduce this setup and have it all in one tool.
