Apps similar to Shipyard.Build include Gefyra, which is free and open source. Other options are mirrord, Telepresence, Signadot and kern. In total there are six Virtualization Tools like Shipyard.Build for Linux, Mac, Windows and self-hosting.
Gefyra gives Kubernetes-(“cloud-native”)-developers a completely new way of writing and testing their applications. Gone are the times of custom docker-compose setups, Vagrants, custom scripts or other scenarios in order to develop (micro-)services for Kubernetes.
Telepresence is an open source tool that lets you develop and debug your Kubernetes services locally while bridging to a remote Kubernetes cluster.
Kubernetes sandboxes create isolated environments for each change by deploying only modified services and routing other requests to shared cluster dependencies. They support pull-request previews, end-to-end and integration tests, local code, resource isolation, and coding-agent workflows.
