LicenseCaadtek uses multiple overlapping protection layers. Even if someone extracts your license key, they can't use it on more machines than allowed, can't fake a server response (HMAC-signed), and can't bypass online checks without your heartbeat failing.
Start free. Scale as you grow. No hidden fees.
