I needed a handy way to migrate content from a stage site to production. The built-in WordPress export/import was insufficient, so I created Maxporter.
Why is it called Maxporter? Named after The Max on SBTB, Maxporter was originally a name for a podcast app I was writing. I stopped that when one of the popular podcast apps included the features I wanted. Conveniently, Maximus is the mascot for the College I built this for, so Maxporter pivoted to become a WordPress plugin.
