It's basically a janky blog+RSS. Architecturally, it's as if there were a simple/standard web/blogserver software that could be hosted freely. The key here is exploiting the standardization of Git and availability of free public Git hosting. Done properly, one could create some packaged blog(+RSS reader) container, but the free hosting support isn't there. You could use GCP free instances, but setting up a domain name+TLS is a barrier, even for some technical folks. The idea is neat, definitely a hack in the traditional sense.
