Penetration testers and red teams validating JWT implementations in pre-production environments should reach for jwt-hack first; it's a focused, free utility that catches common signature bypass and algorithm confusion attacks without the overhead of commercial scanners. The 887 GitHub stars and zero licensing friction mean it gets deployed immediately and shared across teams without procurement friction.
