PHP

PHP powers a vast portion of the web and it runs reliably. Modern PHP (8.x) with strict typing, enums, and fibers is a genuinely capable language. The problem is opportunity cost — TypeScript gives you the same language across frontend and backend, better tooling, and a larger hiring pool for the kind of work we do.

Existing PHP applications don't need rewriting. If it works and delivers value, maintain it. But starting new projects in PHP when TypeScript, Bun, and modern frameworks exist means choosing a smaller ecosystem and a split-language stack for no compelling benefit.
