In order to provide a fully customizable, proven digital experience for visitors, consider optimizing your applications. In other words, let’s not only test the website, let’s test everything! While Optimizely’s Web Experimentation product helps to test and optimize your web experiences, the Feature Experimentation product will help you go further by optimizing your development applications. Feature Experimentation (previously known as Full Stack) is a feature flagging and experimentation platform for websites, mobile apps, chatbots, APIs, smart devices, and anything else with a network connection. Some example applications include search results, promotions, payment options, recommendations, and much more.
