What does the Do Not Type web app actually do?

It blocks all typing input, randomly moves the input field when you hover over it, flashes the background red, plays sounds, shakes the screen, and displays a tally counter each time you try to type. It's intentionally impossible to use.

Is this a real tool I can use?

No. It's a prank entry for the DEV Community April Fools Challenge. It serves zero practical purpose and is designed purely to frustrate and amuse. That's the entire point.

What's the "I'm a teapot" console message about?

It's a reference to HTCPCP (Hyper Text Coffee Pot Control Protocol), a famous 1998 joke RFC written by Larry Masinter about controlling internet-connected coffee makers. The 418 status code was included as a joke and actually became part of the official HTTP specification.
