A general purpose app for the ActivityPub API

Project goals

The goal is to support general purpose and specialized ActivityPub projects including and beyond the micro-blogging domain with a Progressive Web App.

Platform developers should be able to focus on designing novel services and interaction modes without having to re-invent a bespoke API, or adopting one from another project.

End Users of supporting software should be able to use a client to engage with the fediverse.

While much is possible with the ActivityPub API, it is somewhat under-documented, and under-specified.

PWA Client development will proceed, alongside ongoing Specification work.
