We never slow you down
VWO uses asynchronous code to serve your campaign data, compared to synchronous code used by Optimizely.
Simply put, asynchronous means that the code will contact VWO servers in the background, download, and process the test package while the rest of your page continues to load and render in the browser as usual. It’s what keeps your visitors’ screens from flickering.
Optimizely’s synchronous code makes the browser wait until Optimizely can deliver the test package, long enough for visitors to notice.
And in the improbable case of our servers being unavailable, the original page gets loaded, ensuring that your visitors' experiences remain unaffected.
Note: Optimizely offers asynchronous code however, they recommend synchronous code.
