Sandbox comparison · Reviewed July 2026

CodeSandboxvs Run Cloud

CodeSandbox SDK provides isolated development environments backed by microVMs, snapshots, and configurable hibernation. Run Cloud offers a compatible TypeScript path with a broader mobile-agent workflow.

Compatibility layer

Start with the import.

Keep the provider-shaped entry point while you validate lifecycle, network, image, and storage behavior against your application.

Choose CodeSandbox

Stay when its platform is the advantage.

  • Products closely aligned with CodeSandbox workspaces and browser IDE experiences.
  • Teams that want continuous development context after hibernation.
  • TypeScript applications already built around @codesandbox/sdk.

Choose Run Cloud

Move when the agent needs more than Linux.

  • Agents that need sandbox execution plus native iOS simulator automation.
  • Teams migrating a CodeSandbox-shaped TypeScript integration incrementally.
  • Mobile build pipelines that continue into signing, export, and TestFlight.

FAQ

CodeSandbox migration questions.

Is Run Cloud compatible with CodeSandbox SDK?+

Run Cloud provides a TypeScript compatibility entry point shaped like CodeSandbox Sandbox. Core workflows can migrate by changing the import, while workspace-specific and provider-specific behavior should be tested.

Do both products preserve sandbox state?+

Yes, but with different product models. CodeSandbox emphasizes snapshots and hibernating development environments; Run Cloud emphasizes snapshotting and forking agent computers.

When is CodeSandbox the better choice?+

CodeSandbox is compelling when browser IDEs, collaborative cloud development, and existing CodeSandbox workspaces are central to the product.

Why use Run Cloud for mobile agents?+

Run Cloud connects the Linux sandbox to browser-controlled iOS simulators and Xcode builds, reducing the number of infrastructure products needed for mobile coding agents.
