Apollo Client is the most widely used GraphQL client library in the JavaScript ecosystem, providing caching, state management, and data-fetching for React and other frontend frameworks. AIWebsiteDetector identifies Apollo deployments through `__APOLLO_STATE__` — a global object Apollo's server-side rendering support injects into the page to hydrate its client-side cache — an unusually distinctive marker with essentially no false-positive source, since nothing else on the web produces that exact variable name.
