What is Oxrion?
Oxrion is a source code protection system for PHP. It lets you ship your applications to customers and servers without exposing your source code — protecting your work from copying, theft, and reverse-engineering.
If you’ve used PHP code protection before, Oxrion will feel familiar — but it was built to solve one of the biggest day-to-day frustrations with the usual approach.
What makes Oxrion different
Section titled “What makes Oxrion different”Oxrion protects your code once, producing a single encrypted file that runs across multiple PHP versions.
- You protect your code once and download one file.
- That file runs whether your customers are on PHP 8.1, 8.2, 8.3, or 8.4.
- You don’t maintain version-specific packages, and you don’t re-encode when a customer upgrades PHP.
For anyone distributing commercial PHP software, this removes a whole category of busywork and support headaches.
How the pieces fit together
Section titled “How the pieces fit together”Oxrion has two sides: the Cloud, where you protect your code, and the Loader, which runs it.
Oxrion Cloud is where the work happens. You upload a PHP file — or an entire project as a ZIP — choose how it should be protected, and get back the encrypted result with your project structure preserved. The Cloud also includes a Licenser (to issue licenses tied to a domain and expiry) and Recovery (to restore protected files back to source).
The Oxrion Loader is a small, free PHP extension installed on the server that runs your protected code — typically your customer’s server. Install it once, and protected files run like normal PHP. The Loader is free to distribute, so you can ship it alongside your application.
Built-in protection
Section titled “Built-in protection”Every file Oxrion produces is tamper-proof. If even a single byte of a protected file is changed, the Loader refuses to run it. There’s no partial execution and no silent failure — a modified file simply won’t run, which keeps your protected code intact exactly as you shipped it.
Free tools that don’t depend on the Cloud
Section titled “Free tools that don’t depend on the Cloud”Two of Oxrion’s tools — Licenser and Recovery — are also available as standalone downloads. Once you have them, they work completely offline:
- Recovery lets you restore a protected file back to its original source — using a private key that only you hold (available when Recovery Mode was enabled during encryption).
- Licenser lets you generate license files for your customers, on your own machine, whenever you need them.
You’re not locked to the Cloud for these. Generate a license at 3 a.m. with no internet, restore your own code from a backup years later — it’s yours to run independently.
