Overview

Godot Play Billing is an open-source Android billing plugin for Godot 4.2+ that provides seamless integration with Google Play Billing directly from GDScript, eliminating the need to write native Android code in Kotlin or Java.

The plugin is designed to simplify mobile monetization workflows for Godot developers by exposing Google Play Billing functionality through a clean, Godot-friendly API integrated with nodes and signals.
