This is a really cool idea, and very appealing. Also very nice that it looks usable with just an SSH client. It would be useful if it was explained what the companion client is for?

Another small personal gripe: I think you should either remove the 1 line copy/paste sh install on the homepage, or add a link to a git repo on the homepage. I know it's possible to view the sh by visiting it, but a raw text file doesn't give any info about contributors or development process. Current form of no git repo and copy/paste bash pipe on homepage feels like a dark pattern.
