# Embedded Microflow vs. Runtime Microflow Server

Microflow is available for use in two ways. 

**Embedded Microflow**. Users can design a microservice using Microflow and then export it as a jar file to use in other systems. Users can import the jar file to their existing java project and use the Microflow Java APIs to call and execute the microservice. 

\
**Runtime Microflow Server**. Users can also use Microflow as a standalone server mode by installing the Server Runtime and running Microflow through the Web service. In this case, the Microflow is available as a service, and the user can call and execute the microservice using the REST APIs.
