WeChat, which is run by Chinese internet giant Tencent (TCEHY), is often referred to as a "super-app," acting as a one-stop shop that does it all for users. People often joke that it more closely resembles an operating system than it does a traditional app because of how much time people spend on it. In recent years, WeChat has increasingly built its success on an ecosystem of lite apps, which are known as "mini programs."
