can you include a component diagram overview to give folks a quick idea of "what runs where?" before making the decision to try this out.

you wrote that this is local but what's up with the cloudflare subdir? do we need a cf account to run this?

I am a bit confused how I would use this (maybe because I may not be your target audience?).

For example if I am coding with Kilocode and phpstorm. How would I use these microVms and what is the cloudflare worker for? I currently run a regular set of docker containers to run my code, how does this compare?

I hate to speak negatively about someone's hard work but I am genuinely confused as to why this needs to be a separate product/service. Could I not spin up a container or a VM and run my agents in it? What is this sandbox letting the agent do safely that neither the current container or VM solutions are able to offer?
