Agent Ready HTML

Initial HTML

In short

The HTML document a server returns for a URL before any JavaScript runs. A plain-fetch agent reads only this, so the answer has to be in it. Example: In Ora's 19-configuration test, hiding the answer in JavaScript left the plain-fetch client with 0 of 5 answers. Related terms: App shell, Hydration, Plain fetch, Rendered HTML, JSON-LD.
