+Is it possible to use Godot to create non-game applications?
+------------------------------------------------------------
+
+Yes! Godot features an extensive built-in UI system, and its small distribution
+size can make it a suitable alternative to frameworks like Electron or Qt.
+
+When creating a non-game application, make sure to enable
+:ref:`low-processor mode <class_ProjectSettings_property_application/run/low_processor_mode>`
+in the Project Settings to decrease CPU and GPU usage.
+
+That said, we wouldn't recommend using Godot to create a *mobile* application
+since low-processor mode isn't supported on mobile platforms yet.
+
+Check out `Material Maker <https://github.com/RodZill4/material-maker>`__ and
+`Pixelorama <https://github.com/Orama-Interactive/Pixelorama>`__ for examples of
+open source applications made with Godot.
