Lightweight Spotify Extension for Minimalist Browser Users: Zero Polling
An observer-based design that leaves your CPU alone.
💡 Overview
Anything running in the background should be nearly invisible. You keep few tabs and fewer extensions.
Instead of checking the player every few hundred milliseconds, the extension uses a MutationObserver and updates its UI only when the page changes. The developer describes the footprint as near-zero CPU and memory overhead, which matters if you are already running heavy applications.

You keep few tabs and fewer extensions.
The problem: Every extension should earn its place.

🚀 Try It in Three Steps
- Open Chrome Task Manager to see what your extensions use.
- Install the extension and compare over a session.
- Keep what feels invisible.
✨ What You Get
- Zero-polling design: A MutationObserver updates the UI only when the page changes, keeping CPU and memory use low.
- Device quick-switcher: One click to the Spotify Connect device drawer from the mini-player header.
- Sleep timer: Presets of 15, 30, 45 and 60 minutes with a live countdown that auto-pauses playback.
| Task | Switching tabs | Spotify-Web Playback Controller |
|---|---|---|
| Pausing music | Find the tab, click pause, return | One keystroke |
| Volume change | Open the tab, drag a slider | Scroll the mouse wheel over the popup |
| Focus impact | Context switch every time | Your work window keeps focus |
| Resource use | A full tab in the foreground | Observer-based, near-zero overhead |
Note: it works with the Spotify Web Player at open.spotify.com only, and does not control the desktop app.
