NamLoop

Test your YouTube video on endless loop.

A testing tool for developers and marketers — loop a whole video or just an A-B segment, adjust speed, and queue more. For development and marketing-test purposes only.

Plays through the official YouTube embed — no ad blocker needed.

How it works

  1. 1

    Paste a link

    Drop in any YouTube URL or 11-character video ID.

  2. 2

    It loops

    The video restarts the instant it ends — no end screen, no manual replay.

  3. 3

    Fine-tune

    Set an A-B segment, change speed, and build a queue. Settings live in the URL, so links are shareable.
