MetalBear

MetalBear is an Israeli developer-tools company behind mirrord, an open-source tool that lets developers run a local process in the context of a remote Kubernetes cluster — mirroring live traffic, environment variables, and file system access without deploying to the cluster. The project is hosted publicly on GitHub and targets backend engineers and DevOps practitioners who want to test code against a real cloud environment from their local machine.

The primary product is mirrord, which intercepts system calls on the local process and proxies them to a remote Kubernetes pod. The concrete problem it solves is the gap between local development and staging environments: developers can iterate locally while their process behaves as if it is running inside the cluster, consuming real traffic and real dependencies. The target buyer is a DevOps or platform engineering team at a company running microservices on Kubernetes. The project is open-source, and MetalBear also offers a cloud/team tier.

MetalBear is based in Israel. Detailed public information on office location, headcount, and funding specifics is limited.
