Kubeless is built on top of Kubernetes from scratch and is making use of the core Kubernetes primitives (e.g. deployments, services, confimaps, ingress) to avoid re-inventing the wheel. In addition, Kubeless makes use of Prometheus for monitoring functions calls, which is built directly into the runtimes.

With a DevSpace, you can build, test and run code directly inside any Kubernetes cluster. You can run "devspace up" in any of your projects and the client-only DevSpace CLI will start a DevSpace within your Kubernetes cluster. Keep coding as usual and the DevSpace CLI will sync any code change directly into the containers of your DevSpace.
