Vms hosted in Hetzner auction instances is exactly how shellbox works. I published more details in here: https://shellbox.dev/blog/race-to-the-bottom.html
This is pretty cool, I turned a NUC at home into this, and would probably rather use you guys instead. However, is there a way for me to keep a session open without being connected? Sometimes I want the session to be there so I can connect/disconnect to check up on it, so I want "just disconnecting for a bit" to be different from "I don't care about this any more, destroy it".
At home, I've done that with a Zellij session (everything is tied to the session, and quitting Zellij completely means "I'm done with this". Merely disconnecting keeps it running).
Love the website and how you have implemented payments! Also giving each box an email is a nice touch.
Thank you for sharing!
