You can now have Fediverse compatiblity on self-hosted Ghost-powered blogs.
There are two different ways of doing this:
- Install your Ghost blog using Docker, more info at https://docs.ghost.org/install/docker and see the section on #ActivityPub at https://docs.ghost.org/install/docker#enabling-social-web-activitypub. There are no limits on this option.
- Use ghost.org's ActivityPub service, but this has limits for self-hosters of 2000 follows, 2000 followers and 100 interactions per day (more info at https://docs.ghost.org/hosting#hosted-activitypub-usage-limits).
