Apps similar to mirrord include Gefyra, which is free and open source. Other options are DevSpace (for Kubernetes and Docker), Shipyard.Build, Telepresence and BunkerVM. In total there are seven Virtualization Tools like mirrord for Linux, Mac, Windows, the web 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.
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.
Managed ephemeral environments built from Docker Compose for monorepos and multi-repository apps. Automatically deploy PR previews with shareable URLs, logs, secrets, SSO access, integration and E2E testing, plus CI/CD integration.
Telepresence is an open source tool that lets you develop and debug your Kubernetes services locally while bridging to a remote Kubernetes cluster.
BunkerVM is a lightweight runtime designed to safely execute AI agent generated code inside isolated Firecracker microVM sandboxes.
A fast, rootless sandbox and virtual resource runtime for any workload, including untrusted and AI-generated code. Daemonless: a real, kernel-enforced container in ~3.5 ms from an OCI image, no daemon, one 1.52 MB static binary.
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.
