I got nervous that the API changes would be the end of Apollo, and thus largely the end of my Reddit use. So, I made a way to export all of my post and comment data into a searchable SQLite archive:

It can pull your recent activity from the API, but also has support for pulling data from a GDPR archive (a feature I'm very proud of).
