# Oz API vs. Oz API Lite

Liveness and Face Matching can also be provided by the Oz API Lite module. Oz API Lite is conceptually different from Oz API.

* Fully stateless, no persistence,
* Extremely easy to scale horizontally,
* No built-in authentication and access management,
* Works with single images, not videos.

Oz API Lite is suitable when you want to embed it into your product and/or have extremely high performance requirements (millions checks per week).
