The SDK ships a hosted site at sdk.staging.libratech.ai with three tabs: Docs (the SDK README), Changelog, and Playground. The playground is a host page that embeds the current staging build with productId: 'wko_de', mounted inside a simulated app root (mountTarget: 'root', zIndex: 5), so it doubles as a reference integration.

What you can try

The status line at the top of the controls prints what the host receives: init state, whether onClose was called, the last onAuthStateChange payload, the last onAuthError, and the last onCitationClick event (the playground claims every citation with preventDefault() and shows source and url instead of opening a tab).
Open the browser console. The playground logs every callback, which is the quickest way to see the exact event shapes documented in the types reference.

Screenshots on this site

Every screenshot and video in these docs is captured from this playground by the repository’s Playwright harness, so what you see here is the current staging build, not a mock-up.
