Vungle (Liftoff) Playable Live Test
Vungle/Liftoff's click-through is unusual: the primary signal is a postMessage('download') call to the parent frame, with MRAID's mraid.open() only as a fallback if that channel isn't available. Upload your build below and watch it actually run.

5 MB, single file

Outside calls
None allowed — everything bundled in
- Single self-contained HTML file, 5 MB or smaller.
- All assets must be embedded; external requests are prohibited.
- Download/CTA calls window.parent.postMessage('download','*'); MRAID open is the fallback.
- Do not auto-play audio before a user interaction.
Play through your ad in the frame to trigger these — nothing here is assumed, only what your build actually does.
