How Browsers Work

"This exists because most explanations of browsers are either too shallow or too deep to build real intuition."

A short, interactive guide to what happens between typing a URL and seeing a page — DNS, the TCP handshake, HTTP, DOM parsing, and the layout/paint/composite pipeline — with tiny examples you can poke at. Open source.
