CrabboxRemote Execution Control Plane

One CLI. Many Runtimes.

Run Your Code in the Right Box.

Keep editing locally. Crabbox runs the working tree you have on the machine it needs—a local runtime, cloud VM, SSH host, or managed sandbox—then streams the result back. No bespoke CI job for every iteration.

Choose the job Crabbox should help with

Recommended Starting Path

Shorten the edit–run loop.

Start with providers that favor local execution, reusable caches, warm sessions, or other fast-feedback paths.

built-in recommendationsverify after selection
crabbox providers recommend fast-feedbackcrabbox doctor --provider <name>
Open the Fast Test Loop Guide

Recommended Starting Path

Separate agent fit from cleanup guarantees.

Compare agent- and devbox-shaped runtimes with the stricter disposable route, then inspect the selected provider’s isolation, network, secret, and cleanup boundary.

Recommended Starting Path

Match the operating system before the vendor.

Compare the platform routes independently; Windows includes native and WSL2-capable paths, subject to the selected host.

Recommended Starting Path

Start with a visible desktop-capable target.

Compare browser and desktop paths first, then add evidence routing when screenshots, video, or diagnostics must survive the lease.

Recommended Starting Path

Fan prepared state out across multiple attempts.

Start with checkpoint- and fork-capable workspace providers for test shards, branch comparisons, or best-of-N runs.

Recommended Starting Path

Require GPU capability before choosing capacity.

Compare SSH-accessible and delegated accelerator paths for model tests, CUDA builds, rendering, or other GPU-shaped work.

Built-in guidance, not a live provider check. Availability, price, performance, credentials, quota, and security still depend on the provider. Verify readiness with crabbox doctor.

Choose by Ownership

Run Here, There, or Managed.

The loop stays the same. Only the runtime owner, isolation boundary, and billing relationship change.

Local

Stay on this machine

Containers, full VMs, and policy sandboxes for fast checks without cloud credentials.

Use capacity you control

Cloud accounts, SSH hosts, and self-hosted virtualization such as Proxmox or Firecracker.

Provider-Managed

Delegate the runtime

Hosted sandboxes, devboxes, CI proof runners, browser sessions, and GPU jobs.

Current Cost Model

Crabbox Software Is Free. Compute Isn’t.

No opaque “box credit” is needed to understand today’s product. Crabbox separates its software from the infrastructure that runs the work.
