Does it allow access to GPUs and all system resources? That is unfortunately a limitation a lot of these sandboxes often have and you need to run a container or vm to get that.
The big issue with this is though that GPUs are not available. I believe many people have local workstation boxes where they do dev on and need proper sandboxes and stuff like firecracker is also not super useful as afaik GPU passthrough is not ideal/working. Or any kinds of larger HW requirements.
