@onlinepersona i see what you mean now, it is not an obs plugin directly no. I do not enjoy web dev so using the browser plugin source is a no from me. Idk if running Godot is less resource intensive, performance is not really something I'm worrying about at this stage though it will be later.
It is open source in the sense that the source code is openly available, however it is a personal project, it doesn't have a pretty README or documentation about how to use it, and I make 0 promises about fixing open issues/merging prs. If you wanna look anyway it's here:
