Take control of your
REXSA licenses

Serial key licensing
Generate and manage keys with 1-day, 1-week, 1-month or lifetime durations.
Device binding (HWID)
One serial locks to one device, keeping every license exactly where it belongs.
Feature unlocks
Enable exactly the modules a customer paid for — from core tools to premium.
Automatic updates
Ship new versions and the app checks, notifies and downloads the latest build.
