Playground

Test fixtures

Self-contained pages that reproduce the messy, hostile scenarios real sites throw at automation — closed shadow DOM, cross-origin iframes, occluding overlays, honeypots and server-side checks — so you can exercise browser-automation flows against known, stable markup.

Registration flow
/playground/registration_flow
A deliberately hostile sign-up page that stacks the patterns which quietly break naive DOM scrapers and el.click() agents. A cookie wall lives in a closed shadow root hosting a sandboxed opaque-origin iframe (OOPIF), the real submit button sits in its own closed shadow root behind a decoy #submit, synthetic clicks are rejected via isTrusted, hidden honeypots and a full-width mega-menu overlap the fields, and a fake loading gate plus a timed newsletter pop over the page. Validation, account creation, timing/anti-replay checks and a real (dummy-marked) email verification code all run server-side against a Go API — reading the client JS gets you nothing.
