#Emissary is an #Fediverse client and #RSS reader. It uses page metadata (like #OpenGraph data and #MicroFormats) to make every page on the Interwebs work just like an ActivityStreams document.
It works like a cross between self-hosted #IndieWeb blogs and a Mastodon mega-instance, letting one hosting provider serve many individual sites that pool resources (like shared caches and worker queues) while remaining portable and distinct from one another.
