Which frameworks does SitrTech support?

Python: Odoo, Frappe/ERPNext, Django, Flask, FastAPI and Tornado. PHP: WordPress, Laravel and generic PHP projects — nine frameworks in total.

How does SitrTech protect my source code?

Every file is sealed with authenticated AES-256-GCM under its own unique key, then executed by a compiled per-OS/arch/Python native loader. The master key lives only inside that native binary, never in readable code, and each build can be bound to an expiry, domain, IP range, MAC, machine-id, hostname, disk serial or Odoo database.

Will encryption slow down my application?

The impact is negligible. Protected code runs at ordinary Python speed once loaded — there is only a one-time load per module at first import (about 0.1s), and the app then runs fully offline with no per-call cost.

Does my source code get uploaded to SitrTech?

In local mode your source never leaves your machine — encryption runs on your side and only line counts are metered for billing.

Can I lock a protected build to a customer or a machine?

Yes. You can bind a build to an expiry date, a domain, an IP/CIDR range, a MAC address, a machine-id, a hostname, a disk serial or an Odoo database. The rules are enforced locally at runtime and cannot be edited or bypassed.

What platforms does the protected code run on?

Python 3.8 to 3.14 on Linux, macOS and Windows. The same protected build runs everywhere, including fully offline.

PHP Source-Code Protection

SitrTech protects PHP source code so you can sell and deliver WordPress themes and plugins, Laravel applications and plain PHP projects without shipping readable source.

Every .php file is encrypted with AES-256-GCM and runs behind the SitrTech PHP loader; configuration and framework bootstrap files stay intact so your project keeps working.

Bind each deliverable to a customer, domain or time window — the rules live inside the encrypted files and are enforced offline, so a copied build won't run where you didn't license it.

For PHP developers and agencies

Deliver protected client work with offline, source-free licensing.

Encrypt WordPress themes & plugins (wp-config.php stays intact)
Protect Laravel projects (vendor/, config and bootstrap are skipped)
Encrypt any plain PHP project
License and bind each deliverable to a machine, domain, IP or expiry

Encryption instead of encoders

Traditional PHP encoders and obfuscators disguise code, but the runnable logic still ships and can often be recovered. SitrTech encrypts each .php file with AES-256-GCM; the source is ciphertext at rest and only runs through the licensed PHP loader — a stronger model for code you hand to clients.

Common use cases

Where PHP teams protect code before delivery.

Selling a premium WordPress plugin or theme you don't want redistributed
Delivering a Laravel application to a client's own hosting
Licensing a plain-PHP product per customer or per domain
Issuing time-limited PHP trials

Offline and license-bound

Protected PHP runs offline and can be locked to a specific customer, domain, IP range or time window — enforced by the loader, not by a call home.

Frequently asked questions

Will my WordPress plugin still work after encryption?

Yes — every .php file is encrypted with the runtime loader while wp-config.php and required bootstrap files stay intact, so the plugin loads and runs normally.

Can I license per customer?

Yes — bind each build to a machine, domain, IP or expiry so a deliverable only runs where you allow, and use per-customer key isolation so one license can't unlock another.

What PHP versions does the loader support?

SitrTech supports the mainstream PHP versions used in production today. See the documentation for the current matrix.

Does it work on shared hosting?

The protected code runs wherever the SitrTech PHP loader is available for the target PHP version. Check the docs for hosting/extension requirements before you deliver.

Is this stronger than a PHP obfuscator?

Yes — obfuscation leaves recoverable logic in the shipped files, while SitrTech encrypts the source so it is ciphertext until the licensed loader runs it.
