Navigate to the WordPress page you want to capture — local, staging, or live. Local environments (LocalWP, MAMP, XAMPP, Lando, DevKinsta) work perfectly; no public URL is required. If the page requires authentication, log in first so the content renders as it would for a real user.
If you want to capture a specific post, product, or page state — an empty WooCommerce cart vs a cart with items, a logged-in header vs a logged-out one — navigate to or set up that state first. The plugin captures whatever the browser currently displays.
