Username / Password Mutator
Built first-party, modeled on the pattern CUPP and similar OSINT-driven wordlist tools use: capitalization, leetspeak substitution (a→4, e→3, i→1, o→0, s→5), and common numeric/symbol suffixes layered onto whatever you actually know about the target. Only as good as the OSINT behind it — for account creation on a real client engagement, not for guessing at strangers. Nothing here leaves your browser.
