This is the code behind

Entries are collected by multiple distributed volunteers running a user-script, then submitted to a central API server. Submissions require two entries to confirm and show on-site.


In order to use the Cream client, you'll need a working API server. Theoretically you could build this yourself using viewclient/submitter as a reference, but I'd recommend you just use the current server we have.

cd server
npm i
node index.js


The viewclient is served automagically by the server, but you may want to offload the static HTML and JS to something like S3 behind CloudFront to improve performance. It'd be a good idea to babelify viewclient.js before uploading, especially if you're planning on serving the site on a production level.


The submitter is technically universal and can be used with any Cream-compatible API server.

Installing userscript

You'll need a userscript manager, like Tampermonkey or Greasemonkey to start. Then, click here to download and install it.

Setting up the submitter

Go to any Steam search page, like this one. You'll be prompted to enter an API URL. Enter the publicly-accessible URL for your instance, without an ending slash. Then you'll be prompted for an API key. You can add your own by manually modifying the users table; there's no interface for this.

Submitting apps and prices

Click the new blue submit to [your app's domain] button in the right panel. Make sure you have no more than 25 search results on the page. This will submit the prices and other app metadata to your Cream server.
