R3DHULK/HULK — reverse-engineered prompt

Build me a Python app called HULK that helps me understand DDoS attacks and safely test how my own local website handles heavy traffic. I want a simple screen where I can enter a localhost or private test URL, choose how many requests to send, set a delay, start and stop the test, and see live results like total requests, errors, response time, and whether the site is slowing down.

Please make it clear this is only for legal testing on systems I own. Add guardrails so it refuses public targets by default, has sensible limits, and shows a warning before running. I’d like both a basic command line version and a simple desktop GUI if possible. Also include a clear README with setup steps for Python 3, virtual environment instructions, and what to do if package installation fails on Debian. Look up current docs online if you need to.
