At the time of starting the project, stoat did not have screen share capabilities. This was a non starter for our community. Fluxer looked promising, but quickly became overwhelmed by the self hosting docs. Chatter is for small to medium size communities that don't want to spend more time maintaining their app than using it. With chatter you forward a few ports, fill out the compose file, and you're set. Chatter is also a PWA, no native client updates to worry about.
