SpeedSlap v1.2 - YouTube Speed Control

Shipped a little Chrome extension: SpeedSlap

The Problem

YouTube’s built-in speed controls suck. Limited range, clunky UI, no keyboard shortcuts worth a damn.

I watch a lot of educational content at 2-3x speed. Needed something better.

The Solution

SpeedSlap gives you:

• Speed range from 0.5x to 10x (configurable)
• Keyboard shortcuts (customizable)
• Scroll wheel control on the overlay
• SLAP toggle - one key to jump to your preferred fast speed
• Persistent speed across page loads
• Draggable overlay that remembers position

Default Shortcuts

• Numpad + - Toggle SLAP speed (default 3x)
• Backtick - Reset to 1x
• ] / [ - Increase/decrease by 0.5x
• Shift + ] / [ - Fine adjust by 0.1x

Tech

Manifest V3, vanilla JS, no frameworks. Injected content script handles the YouTube player API.

The trickiest part was handling YouTube’s SPA navigation - the player gets recreated when you navigate between videos without a full page load.

Get It

Clone from GitHub and load unpacked in Chrome. Maybe I’ll put it on the Chrome Web Store eventually but the review process is annoying.
