 We run our public script with more than [50 browsers on many different (real) devices](https://github.com/simpleanalytics/scripts/blob/main/test/helpers/get-browsers.js). We support Internet Explorer 9 (not sure who is still using that) and up. Including many mobile browsers and less common devices. We get amazing sponsorship from [BrowserStack](https://www.browserstack.com/). Thanks, BrowserStack!
