Awesome! I remember seeing Datamosh 2 plugin for After Effects, but didn't know it used this open source project. Turns out there is a whole bunch of GUIs for ffglitch: https://ffglitch.org/frontends/

there used to be a running joke in the AfterEffects subreddit that 95% of “What’s this effect called?” questions the answer was datamoshing. I think they even had a bot that would auto answer with datamoshing since it was asked so frequently.
