thundersnap 0.01: an undo button for everything

Happy July 4th! For those of us around the world contemplating<br>independence, it's a good day to think about how we came to rely on<br>expensive cloud infrastructure for our fundamental computing needs.

With that in mind, here is my latest toy project: an open source tool that<br>makes replicating, forking, sharing, and running container snapshots fast<br>and easy across cloud and personal devices.

It's fun to play with, especially on bare metal hardware you run at home, or<br>rent from a provider like Hetzner or OVH. Or, because it uses Tailscale, why<br>not all of them in a single mesh?

There's a lot more to say but I don't have time right now. Details are in<br>the README.

I will say this: humans and AI agents both want the same things when they're<br>trying to get work done. Ephemeral containers aren't really it. But how<br>about unlimited disk space, fast CPUs, an undo button, and the ability to<br>move to whatever provider offers the best hardware at the best price?<br>That's more like it.

Go visit thundersnap on github<br>and tell me what you think!
