The vendOS DevTools have been created to help developers better visualise the communication between their application and the machine.

They are currently in beta, so bare with us as we iron out any bugs and add more functionality. Feel free to email us at [email protected] to report any issues you're having with them.

How they work

When developing your application locally using vendOS JS; there is no vending machine to connect to. This means that the code you use to interact with the machine has very little scope for testing.

The vendOS DevTools attempt to mock the machine that your application connects to; and allows you to respond to requests using a panel in the Chrome Developer Tools.


The vendOS DevTools can be installed from the Chrome Store. Just click the "Add to Chrome" button.

This will install the extension, which can then be accessed from the Chrome Developer Tools.
