oof, I should've maybe filtered my pocket export for dead links somehow before importing it to a new software
nice bonus: I can set the archives to be publicly available so I can link people to my archived version of something, like this: https://shiori.shork.xyz/bookmark/424/archive
Shiori seems quite nice so far, though. It does some basic archival as well as cool stuff like automatic epub export, in case you want to read your saved articles on an eReader.
Pretty easy to set up with Docker, documentation is a bit scattered but there's not much to configure to begin with
