 Devsy is a client-only tool to create reproducible developer environments based on a [devcontainer.json](https://containers.dev/) on any backend. Each developer environment runs in a container and is specified through a [devcontainer.json](https://containers.dev/). Through Devsy providers, these environments can be created on any backend, such as the local computer, a Kubernetes cluster, any reachable remote machine, or in a VM in the cloud.
