We don't limit concurrency on the builder VMs. When you create a project you are effectively getting a dedicated build VM with a persistent SSD cache for each architecture you want to build for. We run native BuildKit on the VM and connect your `depot build` directly to the builder instance via mTLS. So your concurrency is unlimited with Depot as well (or at least as unlimited as BuildKit will allow for).
