Since Processing 4.0, you can bundle sketches as double-clickable .pdez files and Libraries/Modes/Tools as .pdex files for easy sharing and installation. (see Processing #73, Processing #3987, and the release notes for 4.0 beta1)

A great next step would be to allow .pdez and .pdex files to be opened in the PDE directly from a url in a web browser. This would enable easier sharing of sketches on the forum, better UX for multi-tab examples on the website, and open the possibility for online Processing sketch galleries.

This would require the user to register the protocol on their system (which I imagine could be done from the PDE ?) For example, this page describes the steps needed to register a custom browser protocol on Window, macOS and Linux. There is also a W3C documentation page about custom scheme and content handlers.
