About Crabbox
Crabbox is an on-demand computer platform for agents that runs tests and builds in isolated boxes. It serves developers and QA teams who need reproducible remote compute without tying up local hardware.

Key Features
From the tester’s perspective, Crabbox coordinates remote boxes for parallel work, reuse of warm environments, and cross-platform validation, so teams can iterate faster without rebuilding local setups:
Parallel runs
Run tests and builds on separate boxes, so agents don’t compete for your laptop’s CPU, RAM, and ports.
Warm boxes
Reuse prepared environments to cut provisioning time between iterations.
Cross-platform targets
Choose Linux, macOS, Windows native, or WSL2 to catch platform differences from the same checkout.
Interactive desktop access & portal
Open desktops with VNC or WebVNC, request a browser, or use VS Code in the browser with —code; the coordinator portal shows leases and run logs.
Summary
Best for: development teams, QA engineers, and platform/DevOps groups coordinating remote, parallelized tests and cross-platform validation.
