I keep seeing projects like this pop up and they never nail it.

I need isolation, but I also need to give my agents secure access to internal package registries, logs, internal infra, designs, emulators, browsers, docs etc. At a large company, work can span dozens of repositories. And on top of that, I need dozens of these.

I built this at work. Engineers use krunkit VMs with proper memory ballooning, GPU acceleration. Retina RDP, credential injecting proxy for etc.

This seems like a fun toy for single project development, but nothing close to what you need as an engineer in a corporate environment.
