Anti-tamper for paid software. Ships inside your binary. No server dependency.

We instrument your binary with the checks, integrity guards, and machine-lock that make a working crack expensive to produce and stale by the next release. Nothing runs on our servers at run time. The whole thing ships with your build.

What we do

Paid software gets cracked. Sooner or later, someone finds the license check and patches it out. We can't make that impossible. Anyone who says otherwise is lying.

What we can do is raise the cost. We add layered checks, integrity guards, and a per-machine binding that makes any patch narrow, fragile, and specific to one build. The next release invalidates most of the work.

The goal isn't uncrackability. It's a shelf life short enough that no one keeps producing cracks for you.

How it works, roughly

Broadly: critical branches sit inside a virtual machine whose shape changes between releases. The binary knows which machine it's running on and won't accept a copy dropped on a different one. Integrity checks reference each other, so patching one out breaks others in ways that aren't obvious for a while.

Nothing lives on our servers or requires a network connection at run time. Your users install one binary and it just runs: offline, air-gapped, wherever.

We keep the specifics out of public copy. If you want the details, we'll walk through them under NDA.

The honest version

It won't stop a nation-state or a determined lab with unlimited time. It will stop the Discord groups and weekend cracker circles that most paid software actually loses money to.

You get: a much shorter shelf life on any published crack; a per-machine binding that kills casual sharing over cloud drives; and one less thing your product team has to think about with every release.

Everything ships in your binary: you audit it, you own it, and it never has to phone home to run. Your users never notice we're there; they just see your product working.
