Video Demo

From a lesson stuck at normal speed to exactly the speed you want, in a couple of key presses.

Any video, any speed

Works on HTML5 video and audio on almost any site, with keys, a speed box on the video and a menu.

⌨️

Speed keys

D faster, S slower, R back to normal, G for your favourite speed.

⏪

Skip back and forward

Z jumps back 10 seconds and X jumps forward, handy for catching a missed line.

📏

0.1x to 16x

Go far past the 2x most players stop at, or slow right down to follow along.

📦

Speed box on the video

A small box shows your speed, then fades away. Drag it anywhere on the player.

🖱️

Menu and slider

Click the icon for 1x to 3x buttons, plus and minus, and a slider.

💾

Remembered per site

Open the site again and your speed is already set, shown on the toolbar icon.

🛡️

Keeps your speed

When a site keeps putting the speed back to normal, SpeedGeek puts yours back.

🎛️

Your keys

Change every key, the speed step, the skip time and your favourite speed.

🔍

Finds every video

Works with videos that load later, inside frames and in open shadow roots.

How to install it

About a minute, and you only do it once. Store listings for Edge and Firefox are on the way.

📥

Download and unzip

Download the ZIP and unzip it somewhere you will keep it, such as Documents. The browser runs the extension from that folder, so leave it there.

⚙️

Open your extensions page

Type chrome://extensions in the address bar. In Edge use edge://extensions, in Brave brave://extensions.

🔧

Switch on Developer mode

The switch is top right in Chrome and Brave, and bottom left in Edge. It just lets you add an extension from a folder.

📂

Load unpacked

Click Load unpacked and pick the speedgeek folder. Then pin the SpeedGeek icon from the puzzle piece menu.

On Firefox, download the Firefox version, open about:debugging, choose This Firefox, then Load Temporary Add-on and pick the ZIP. Firefox removes temporary add-ons when it closes, so the Firefox Add-ons listing will be the easier option once it is approved.


See it in action

Every step, exactly as it looks in your browser.

Frequently Asked Questions

Is SpeedGeek really free?

Yes. There is no Pro version, no ads and no limits. It is open source under the GPL-3.0, so you can read every line of it on GitHub.

Does SpeedGeek collect any of my data?

No. Everything happens in your own browser. There is no account, no analytics, no remote code and nothing is sent anywhere.

Does it work on YouTube?

Yes. It works on YouTube and most sites with HTML5 video or audio, including courses, podcasts and streaming sites.

Why does it ask for access to every site?

Only if you choose On every site on the welcome page, so your keys and remembered speeds work as soon as a page opens. Choose Only when I click the icon and it needs no site access at all.

Can I change the keys?

What if a site keeps resetting the speed?

SpeedGeek puts your speed back each time. Turn off Keep my speed in the settings if you would rather the site wins.

Does it work on Firefox?

Yes. Download the Firefox version from this page. A Firefox Add-ons listing is in review and will make installing it permanent.

Firefox itself mutes sound below 0.25x and above 4x. Chrome and Edge keep the sound.
