Hello, Fediverse! I’m trying to decide what topic to present at FOSDEM 2027 – Social Web Devroom. Which of these two would you be more excited to hear about? DrFed: DrFed is an ActivityPub debugging tool that @hongminhee@hackers.pub, @z9mb1@hackers.pub, @gaebalgom@hackers.pub, and I are building as a team. fedi.blue: fedi.blue is a library for building servers that interoperate with the ActivityPub and AT protocols.
