Some of you have already heard of us as #Fedify Studio. We now have a proper name: DrFed, short for “Doctor Fed.” We've also just received funding from @nlnet, through the NGI0 Commons Fund.
#DrFed is a web app for debugging #ActivityPub interoperability failures. When two implementations don't federate, the slow part is usually figuring out where the exchange broke: signing, JSON-LD processing, WebFinger, or something less obvious. DrFed's first job is to show where it failed.
We're the team behind @fedify: @2chanhaeng, @gaebalgom, @hongminhee, and @z9mb1. We'll post updates when there's something to try.
