Symfony Website Examples

Symfony is a mature PHP framework and component library used by enterprises, agencies, and open-source projects (it also powers large chunks of Drupal and Laravel internally) for building complex, long-lived web applications. Its most distinctive fingerprint is the Web Debug Toolbar and profiler that Symfony renders in development mode — recognizable by the `sfwdt`-prefixed element IDs and `/_profiler/` routes — alongside the `X-Debug-Token` response header its profiler bundle sets. Because these markers only appear when debug mode is left on, Symfony detection is strongest on staging environments, internal tools, and freshly-scaffolded projects that haven't yet been locked down for production — incidentally also the environments most likely to reveal whether a project was AI-scaffolded in the first place.
