Dialogue Manager is an addon for Godot 4 (there's a Godot 3 version too) that provides a stateless branching dialogue editor and runtime. Write your dialogue in a script-like way and easily integrate it into your game.
You can install it via the Asset Library or downloading a copy from GitHub.
Dialogue Manager is made by Nathan Hoad with help from these cool people.
