httpstat.us is the perfect website for trying and learning any HTTP status and its meaning.

You want to test a 500 Internal Server Error HTTP response in your fancy frontend app but your local development server simply doesn't want to fail (lucky you!)? Just make a request to https://httpstat.us/500

You want a teapot? Just make a request to https://httpstat.us/418
