The map

What runs where on the web: in your browser, on a company's servers, or at another service. Once you have this map in your head, you can tell when an AI's answer, an agency's quote or a colleague's plan doesn't add up.

  1. The request pathWhat happens between typing an address and seeing the page, and where along the way things can get slow or break.
  2. Front and backWhich parts of a site run in your browser and which run on a server, and which part each tool or service takes care of.
  3. Where data livesWhere information is kept, in a company's database, in your own browser or at another service, and what difference that makes.
  4. Public and secretAnything a site sends to your browser can be read and changed by whoever uses it, so secrets and rules have to stay on the server.
  5. What keeps runningWhat has to keep running, be renewed and be paid for once a site is live, and what breaks when one of those stops.
