Product idea: A program that makes your web app masquerade as any language that you choose! It rewrites and hides your .php extensions, and replaces error pages to make them look appropriate for the chosen technology stack. All the actual js is obfuscated & compiled to WASM to hide the shameful use of jquery/react/angular/vue/whatever is no longer the 'in' tool. You can switch technologies with the push of a button!

A "tech stack spoofer", that would be cool and it can have applications beyond that like for security by obscurity.
