Short answer: A mock cloud is a paid collaboration layer for a separately maintained mock; a Hub hosts the mock and the docs together from the spec, so the hosted surface cannot be out of sync. The first is a shared mock; the second is a shared contract.

What a mock cloud provides

Hosted access and collaboration around the mock file. It is the right tool when the mock is a standalone artifact a team shares.

What the Hub provides

PropertyMock cloudHub
Hosted surfaceMockMock + docs
SourceMock fileSpec

Why the shared host matters

When the mock and the docs are hosted from the same spec, they are aligned by construction and a reader and an agent see the same surface.

The decision rule

Use the mock cloud for a standalone shared mock. Use the Hub when the mock and the reference should be hosted together and stay synced.
