Overview

A completely useless, single‑file web app that lets you talk to a virtual teapot using the Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0) from the legendary RFC 2324 (published April 1, 1998).

You can issue real commands such as:

  • BREW / POST (coffee)
  • GET coffee
  • POUR
  • PROPFIND metadata
  • TEA (RFC 7168 extension)
  • SHAKE TO STIR (works on mobile with device motion)

Every command returns HTTP/1.1 418 I’m a teapot, complete with sarcastic quotes from the RFC, live request logging, and fun CSS animations (boiling, dancing, pouring imaginary nothing).

It solves zero real‑world problems, will never brew coffee, and exists purely to make you laugh, waste ~30 seconds of your life, and say “IYKYK”.

Why an Ode to Larry Masinter?

On April 1 1998 Larry Masinter slipped “short and stout” into an official standards document, giving the internet the eternal 418 status code. This silly interactive teapot is a love letter to that beautiful act of internet chaos.

Live Demo

Open the teapot right now – or save the HTML file locally (see below) and open it in any browser; it works offline.

How to Use

  1. Copy the entire code block below into a file named im-a-teapot.html.
  2. Open the file in any modern browser.
  3. Interact with the teapot using the commands listed above.
