# What is the JS Bridge?

The JS Bridge is essentially a communication layer between your website and the mobile app, acting as an API. It enables you to access mobile-specific features directly from the web environment, allowing for more dynamic and integrated user experiences. You can trigger actions, gather data, or change app settings in real-time—all from the website backend.
