# Compatibility

> What the SDK and CLI support on microsandbox cloud today

<Note>
  microsandbox cloud is in [private beta](/cloud/overview). This page was last reviewed on **August 2, 2026**. Capabilities that are limited or unavailable today are actively being worked on, and will move up this page as they become available on cloud.
</Note>

The SDKs and CLI expose one surface for both backends, and almost all of it behaves identically on cloud. This page lists what works today, what is limited, and the recommended alternative for anything not yet available.

## Fully supported

The core workflow (create, execute, connect, persist) is identical on both backends.
