When would you use this?
You know 200 is OK and 404 is Not Found. But what about 307 vs 308? What's the difference between 401 and 403? What even is 418? This searchable reference covers all the status codes you're likely to encounter in real web development, colour-coded by range (2xx green, 4xx amber, 5xx red) so you can scan quickly. Click any row to copy the code and name or search MDN links for more information.
