DrFed
Web-based development and debugging platform for ActivityPub
DrFed is a web-based tool for debugging ActivityPub federation failures. ActivityPub implementations often differ in small but important ways, and developers may have to inspect cryptographic signatures, JSON-LD processing, and object discovery by hand to find out why two servers do not federate. DrFed makes these failures easier to trace. The tool includes an activity monitor showing where delivery failed and at which stage, inspectors for ActivityPub objects and WebFinger responses, a step-by-step signature debugger covering the signing schemes used across the fediverse, a JSON-LD toolkit that shows how different implementations process the same document, and an activity builder for constructing and sending test activities. DrFed can be self-hosted but is also available as a hosted service.
