# Config- or Admin-Server decision In the GRAVITY server may serve as a standalone config server (for the browser plugins configuration) or in combination with the rest of the GRAVITY admin functionality. Please see the [[Browser Extension#Dedicated On-Premise Plugin]] to point to your on premise GRAVITY config server. Three variations are possible: - **Standalone GRAVITY Admin server** (Config will be done through the public GRAVITY config server). Can be set in the Admin UI as ‘Default'. - **Standalone GRAVITY Config server** (Needed for on premise browser plugin configuration). Can be set in the Admin UI as ‘Config endpoint'. - **Combination of GRAVITY Admin and Config server**. On server in a on premise environment has both functionality in one services combined. Can be set in the Admin UI as ‘All'. The required mode can be set in the GRAVITY admin interface: Settings → Admin Site → UI mode: ![[config_or_admin_server_decision.jpg]]
