Preload Strategy

Only load duration/dimensions (default)

Paste any URL. We automatically detect MP4, HLS, DASH, YouTube, and Vimeo so you don't have to.

Watch network events, quality switches, and errors pop up as they happen.

Generate a link that restores your exact test environment—source, settings, and referrer included.

Drag and drop any local video file to play it in-browser with full diagnostic tracking.

Download a structured JSON log of the full playback timeline and any errors encountered.

Three steps to test and debug any video stream

Drop a link or drag a file right into the player. We'll detect the format and start loading the video.

As the video plays, the debug panel tracks the connection status, resolution, bitrate, and network events as they happen.

Generate a shareable URL to let someone else see your exact test environment, or download a JSON debug log to review later.
