# Products

Litmus offers three products, each with its own API surface. They are designed to work together (edges register with the manager, edges and the manager publish to UNS), but each can also be used standalone.

Every endpoint in every product is also runnable in the [Litmus API Portal](https://api.litmus.io), our executable Postman collection.
