That looks really interesting! Congrats on shipping. I’m glad to see more people implementing “headless” AP servers.

The one piece of feedback I have: your outbox seems to have no pagination and it’s only showing updates for your actor profile. So there is no way for someone to use browse through your posts or use the outbox as a “RSS feed” of sorts. It’s also embedding the whole object, all the time. If you are just serving static files (which are easy to cache), perhaps it would be better to just provide a stable URL for the objects, and then just return the document id in the “object” field?
