A reimplementation of Winamp 2.9 in HTML5 and JavaScript.

As seen on TechCrunch, Motherboard, Gizmodo, Hacker News (1, 2, 3), and elsewhere.

Give it a try!

Works in modern versions of Edge, Firefox, Safari and Chrome. IE is not supported.

Use Webamp in your own project

I've tried to make it possible to include Webamp in your own project.

See the usage documentation for more information.


# Or: npm install
npm start

Open http://localhost:8080/webpack-dev-server/ in your browser.

# Run tests and lint checks
npm test


npm run build
npm run serve

Open the local ip/port that is output to the console in your browser.


npm test

This will run both the tests and the linter.


Netlify watches GitHub for new versions of master. When a new version is seen, it is automatically built using npm run build and pushed to the server. Additionally, Netlify will run a build on every pull request and include a link under the heading "Deploy preview ready!". This enables easy high level testing of pull requests.

In short, deploying should be as simple as pushing a commit to master.

Additionally, if you want to fork the project, deploying should be as simple as setting up a free Netlify account.

Advanced Usage

There are some "feature flags" which you can manipulate by passing a specially crafted URL hash. Simply supply a JSON blob after the # of the URL to change these settings:

  • skinUrl (string) Url of the default skin to use. Note, this file must be served with the correct Allows Origin header.
  • audioUrl (string) Url of the default audio file to use. Note, this file must be served with the correct Allows Origin header.
  • hideAbout (boolean) Selectively hide the byline and GitHub link at the bottom of the page. Useful for taking screenshots.
  • initialState (object) Override the initial Redux state. Values from this object will be recursively merged into the actual default state.

Note: These are intended mostly as development tools and are subject to change at any time.

Thank you to Justin Frankel and everyone at Nullsoft for Winamp which inspired so many of us.


While the Winamp name, interface, and, sample audio file are surely property of Nullsoft, the code within this project is released under the MIT License. That being said, if you do anything interesting with this code, please let me know. I'd love to see it.
