Implementing and testing ActivityPub on localhost is incredibly painful - if it’s even possible in some cases. I really wish there were a self-hosted service that could simulate other ActivityPub instances, runnable on multiple ports with alias-based addressing. Being able to locally test federation traffic, security scenarios, and edge cases would be amazing. 🫣
