Make your PHP software
impossible to copy
Encrypt your source and run it on your customer's server. Every installation binds to a domain; suspend the licence from your panel and it stops within minutes.
For PHP developers selling licensed software
If you sell one product to many customers you have two problems: the code gets copied, and you cannot tell who runs which version. This solves both at once — and your customer keeps running on their own server.
Working in four steps
Install the module
You create a PHP folder on your own domain (licence.yoursite.com). Download it from the panel, upload it, and the setup wizard does the rest.
Encrypt the source
Upload your software's source; every PHP file is encrypted with XSalsa20-Poly1305 and turned into a working package.
Issue a licence
You issue a licence per customer: how many installations are allowed, which domain it binds to, when it expires — all yours to decide.
Deliver the package
The ZIP is specific to that customer; it carries their licence key and an invisible watermark. A leaked copy can be traced back.
What comes in the box
Source encryption
Each file gets its own nonce. Entry files stay readable, so your software keeps working exactly as before.
Domain lock
Each seat pins to the domain it first activated on. Installing the same licence on a second site is refused.
Remote revocation
On a refund or a breach you suspend the licence; the installation locks on its next heartbeat.
Seat management
When a customer moves servers you release the old seat and open a new one. You always see how many installs are live.
Store integration
A WooCommerce plugin is ready: an order issues the licence automatically and hands the customer their package.
Outage tolerance
Even if your server is unreachable, your customer's software keeps running. Your downtime is not their problem.
