Hello @PerspexSphinx,

See:

> **[GitHub - fathominfo/processing-p5js-mode: A simple editor for p5.js code that runs inside...](https://github.com/fathominfo/processing-p5js-mode)**
>
> A simple editor for p5.js code that runs inside the PDE

This does not seem to be in active development and also states:

> This is not an official [Processing Foundation](https://github.com/processing) project

Some options here:

> **[Setting Up Your Environment](https://p5js.org/tutorials/setting-up-your-environment/)**
>
> Layla Quiñones, Jaleesa Trapp

_Google Gemini_ lists a number of others when asked:

> Yes, there are other development environments for p5.js, beyond the official Web Editor, VS Code, and the Processing IDE with p5.js mode:  
> \*\*\* I removed the details… \*\*\*

I omitted the details and will leave that search for you to explore.

I can resume using the _p5.js web editor_ now that sketches can be private:
