Built for developers who ship

Every feature is on by default. Toggle what you need, ignore the rest.

Anti-Debug Shield

Detect devtools, debuggers and tampering attempts in real time.

String Encryption

Every literal is wrapped, encoded and decoded only at runtime.

Control-Flow Flattening

Restructure logic into opaque state machines that resist analysis.

JS + Python

One engine, two languages. Same protection, native-feeling output.

Self-Defending

Output detects modification and refuses to execute when broken.

Instant Output

Server-side engine returns hardened code in milliseconds.
