Yes, the big benefit, to me at least, is being able to access bash or zsh history on multiple machines. I'll spin up a server for testing or to add workers to some job and it's really quick and convenient to install bashhub the new machine. I just wasn't comfortable using the open-source client to send all my shell history to a closed-source backend and wanted better command querying so I wrote the bashhub-server. If you're primarily working on one machine I'm not sure how beneficial it is if at all, but if you find yourself using ssh somewhat frequently it's really nice.
