# Web-Based Console (*.esper.cloud)

The Console requires Chrome v57 or above. At present, viewing the console on mobile devices is not supported.

Targeted Dedicated Devices must run Android version 4.4 KitKat (API Level 19) or above. However, we recommend that devices running Android version 7.0 Nougat (API Level 24) or above be used with Esper.

Esper Development Devices running Esper Enhanced Android will always be supported be used. Such devices open up additional features for developers, when using Esper.

# Infrastructure
