A curated reference of PHP tools, libraries, and self-contained applications worth knowing. Updated over time as good things surface.

The PHP advantage in 2026: Runs on shared hosting, no Docker required, no root access needed. A $5/month cPanel host can run most of these. That's still a superpower.

“Don't forget PHP” — it runs everywhere, needs nothing, and often outlasts the
framework of the week.

• Prefer zero-dependency or single-file tools where possible — they survive

longer and deploy anywhere.

tool requires Docker or root, note it.

• “No database” is an architectural choice, not just a convenience. File-based

tools are portable, backup-friendly, and Git-compatible.

half of Symfony for one feature is a different beast than a focused library.
