What is the Loader?

The Oxrion Loader is a small PHP extension that runs your protected code. A file protected with Oxrion is no longer plain PHP — it can only execute on a server where the Loader is installed.

Install once, run anything

Section titled “Install once, run anything”

You install the Loader once per server. After that, every Oxrion-protected file runs like normal PHP — your application includes, routes to, or executes them exactly as before. No code changes are needed in your application.

A single protected file also runs across multiple PHP versions, so you don’t need a different Loader build or a re-encoded file each time a server’s PHP changes. (You do pick the Loader build that matches each server’s PHP when you install it — see Choosing the right build.)

Free to distribute

Section titled “Free to distribute”

The Loader is free. You can ship it alongside your protected application and install it on your customers’ servers without any licensing on the Loader itself. Your customers don’t need an Oxrion account to run your protected software.

Tamper-proof by design

Section titled “Tamper-proof by design”

Protected files are tamper-proof. If a single byte of a protected file is altered, the Loader refuses to run it — no partial execution, no silent fallback. Your code reaches the server exactly as you shipped it, or it doesn’t run at all.
