Chrome extension alternative

A web-based alternative to Looper for YouTube extensions

Chrome extensions sit on top of the real YouTube page and are genuinely convenient. But they break when YouTube updates, they require broad permissions, and most still only do single A-B loops. Multi Looper offers the same "no-install" simplicity with multi-section sequential playback.

Open Multi Looper in browser

Looper for YouTube, A-B Repeat, and YouTube Loop Repeater are the three most common Chrome extensions for looping parts of YouTube videos. They solve a real problem, but extensions come with hidden costs: they demand permissions to read YouTube pages, they break when YouTube updates its DOM, and they depend on the Chrome Web Store's approval cycle for fixes.

If you are looking for a "no install" alternative that still handles serious practice use cases, Multi Looper is a web app that runs in any modern browser with zero setup.

Why extensions break

Extensions that add UI to YouTube work by inserting elements into YouTube's DOM. When YouTube changes a class name, a selector, or a layout, the extension's injection point disappears and the feature silently breaks. Fixing it requires an extension update and a Chrome Web Store review. Reddit discussions about YouTube loopers frequently mention extensions "stopping to work after updates."

Multi Looper is not injected into YouTube. It embeds the official YouTube IFrame player and talks to it through the documented YouTube Player API. That API is stable and maintained by Google. When YouTube updates, the IFrame player keeps working — and so does Multi Looper.

Permission model

Chrome extensions for YouTube typically request permission to read and change data on all YouTube pages. Most are honest, but the permission is still yours to grant and revoke. Multi Looper is a normal web page — the only permission involved is whatever YouTube itself requests when you paste a video URL.

Multi-section workflow

Looper for YouTube and A-B Repeat both implement a single A-B pair. "YouTube Loop Repeater" adds multiple named loops per video, which is a meaningful step up — but those loops are not played in sequence automatically; you select one at a time.

Multi Looper's multiple sections are all first-class and are played in sequence when you hit play. For a real practice session that walks through a song in phrases, the sequential aspect is what makes it hands-free.
