For ETS2 & ATS mod authors
Protect the work
you've spent months creating
GMC Community Locker packages your Euro Truck Simulator 2 and American Truck Simulator mods into protected archives that load normally in-game while making casual extraction and repackaging with third-party tools significantly more difficult.
Built for creators whose work keeps getting repackaged
Every protection layer exists because it addresses a real extraction technique—not because it was added for marketing or complexity.
Layered protection
Over a dozen independent protection techniques work together against extraction tools while leaving the game's loading process untouched.
Per-machine licensing
Machine-specific licensing ensures GMC Community Locker can only be used on authorised machines.
Signed auto-updates
The application automatically checks for and verifies updates, to ensure you've always got access to the latest legitimate version of the locker with latest protection algorithms.
A tool that gets out of your way
No complicated setup or steep learning curve. Add your package, choose your protection settings, and let Locker do the rest.
