Imagine you can stream all your music from home, to any device, where ever you are. That is Subsonic! Now imagine having a Web App to stream your music that is as beautiful and well designed as it is functional, that is Jamstash!


  • HTML5 Music Streaming App for your Subsonic server
  • Browsing and Streaming of Live Music

  • Podcast support (includes description field on hover)
  • Favorite/Starred support for Albums & Songs
  • Shortcuts supported
  • Easy installation (Chrome App or manual install)

  • Light/Dark Theme
  • support
  • Autopilot Mode (click one button and songs continue to play)

  • Built with AngularJS

Please submit all bug reports & feature requests via the GitHub page

You will need a Subsonic server to be able to play your own music. Subsonic is a free, web-based media streamer, providing ubiquitous access to your music. Use it to share your music with friends, or to listen to your own music while at work. Please see


  • You will have to allow Jamstash to "Access your data on all websites". This is required because your Subsonic server could be at any URL http://*/* or https://*/*. This is somewhat misleading, we ask for *://*/* access so that developers can make API calls to ANY URL ...

We don't collect any personal data and we don't want access to your data on all websites, we simply have to use that permission so developers can use the App on all urls.

Setting up your environment

In order to build Jamstash, npm is required. For help installing npm, see

Once npm is installed, clone the project to your local machine using git.

Install the project's dependencies by running npm install && npx bower install.

Development and testing

To start a server that will continuously build and test your code as you work, run npx grunt serve. This will open up a browser window with the built app running in it, as well as a Chrome browser window that runs unit tests. Whenever you change a file, the application is rebuilt and unit tests are run. Stop the server with CTRL+C.

To generate test coverage reports, run npx grunt coverage. This will run unit tests as you work and generate a code coverage report. Stop it with CTRL+C.

To do a one-off build of the code, run npx grunt build. This will also minify the files for use in production. At this point, the files in dist/ can be served up via Apache, Nginx, or any other web server to provide access to the Jamstash application.

Version bumps and deployment to GitHub Pages

Typically these tasks will be done by a project maintainer.

Jamstash uses Semantic Versioning. The following commands can be used to increment the project version across package.json, bower.json, and manifest.json:

npx grunt bump:major
npx grunt bump:minor
npx grunt bump:patch

The public changelog is located in app/common/json_changelog.json. When bumping the version, make sure to add any notable user-facing changes in this file.

After bumping the version, modifying the changelog, and committing the updated files, use git tag <version> to tag the commit with the current version.

Once this tag is pushed to GitHub, GitHub Actions should automatically build it, release it, and deploy it to the 'gh-pages' branch (which is served by GitHub Pages).

If this automated process fails, or GitHub Actions is not available, updating the 'gh-pages' branch can be done locally. The script has been provided to automate this process. Run ./ --help for more information.

An example of the entire release process:

# bump the version
npx grunt bump:patch

# note changes in the changelog
vim app/common/json_changelog.json

# commit the files
git commit -am "Bump version to v1.2.3"

# tag the commit
git tag v1.2.3

# push the commit and tag to the repo
git push origin master --tags

Extra steps required if not using GitHub Actions:

# update the gh-pages branch with the current release
./ v1.2.3

# push the newly-released version to GitHub Pages to deploy it
git push origin gh-pages
