Looks nice.

We rolled out our own that does pretty much the same thing but perhaps more because our solution can also mount persistent storage that can be carried between multiple runners. It does take 1-5 seconds to boot the environment (firecracker vms). If this sandbox is faster I will instruct the team to consider for fast starup.

This is also very similar to Vercel's sandbox thing. The same technology?

What I don't like about this approach is the github repo bootstrap setup. Is it more convenient compared to docker images pushed to some registry? Perhaps. But docker benefits from having all the artefacts prebuilt in advance, which in our case is quite a bit.

I browsed through the documents but it does not seem to be possible to auto destroy a sandbox after certain amount of idle time. This forces who ever is implementing this to do their own cleanup. It is kind of missed opportunity if you ask me as this is a big pain. It is sold as fire and forget but it seems that more serious workflows will require also a lot of supporting infrastructure.
