Crabbox

Crabbox: Developer CLI tool that runs repository commands in local sandboxes, cloud VMs, or SSH hosts by syncing the working tree and streaming output.

Crabbox is a CLI tool that executes repository commands across local, cloud, or remote infrastructure environments. It synchronizes the user's working tree with a selected runtime, such as a cloud VM, SSH host, or managed sandbox, and streams the execution results back to the local terminal. This allows developers to test code in specific environments without creating custom CI jobs for every iteration. The software acts as an interactive workload router, separating the execution coordinator from the underlying compute costs. It supports configurations for various providers, including local containers, cloud-based instances, and GPU-backed capacity.
