I've been using Archivebox for years also, but it recent years it started to have multiple issues. My queues are full of pages that failed to scan, and it's been several versions since I actually had anything new there.

I did small amount of troubleshooting a few times with no resolution, but now I'm thinking of switching my thought process. Maybe something like a "web clipper" is much better, as complex SPA pages often fail to archive well anyway. And I should focus on content itself, not the page. That SingleFile extension fits well here as well.

Did you run into similar dilemmas at some point?

It's funny - I actually went through a similar transition and also realized it was a little too heavy-duty for my personal workflow.

At this point I'm using Linkding (self-hosted bookmarks, which has an archive function) paired with Singlefile (which integrates with Linkding) which locally captures and uploads. For larger, or multi-page, captures I still fire off an Archivebox command. I run into blocks occasionally, but it also just feels like the open web is becoming less and less open in general.
