Self-hosted dev sandboxes with preview URLs (Docker, Go, no K8s)

I think the idea here is to provide this as a way to host/manage multiple different test apps, or apps for a team, or maybe you're just building one of those 'our AI will build you a web app' services. Definitely overkill for one-off projects.

As much as the 'no kubernetes needed' thing is nice, it would be nice if it had a 'yes kubernetes' option for those of us who have a k8s cluster available and want to yeet things into it or do more meaningful network restrictions/sandboxing/etc.

I started using the Sandbox CRD: https://github.com/kubernetes-sigs/agent-sandbox

And if I really need to kick off a box very quickly, OpenRouter Spawn seems like it'll do 95% of what I need it to do: https://github.com/OpenRouterLabs/spawn

Still missing better restrictions though.

If you’ve got a k8s cluster, review apps are completely solved, right? You only need this if you’re in the niche of “no k8s, no PaaS”.
