FastMock is positioned as an API Mock / simulated data service, usually used for frontend-backend separated development and integration testing, comparable to similar Mock API tools. Since no source material was provided, details such as core capabilities, collaboration workflows, and permissions cannot be verified, and unconfirmed selling points should not be added.

For self-hosted deployment, the materials do not provide installation methods, dependencies, or CPU, memory, and storage requirements. Users in China also need to confirm WeChat ecosystem compatibility, support for domestic SMS / object storage / CDN providers, and network access conditions.
