For merchants to be successful, their online stores must have best-in-class speed and user experience. Apps can easily slow down performance, and we require apps to keep performance top-of-mind while helping merchants, to follow our performance requirements and best practices, and to test that their products continue to meet our minimum requirements for speed.
To be published in the Shoplazza App Store, your app must not reduce Lighthouse performance scores by more than 10%. Submissions are evaluated based on this criteria, using the testing methodology outlined in the section below.
The tool used by Shoplazza to test app performance is Lighthouse. Lighthouse is an open-source, automated tool for improving the quality of web pages. It's available in the Developer Tools panel of Google Chrome, so you can test your app directly in the browser.
