    The Agora Web SDK is a real-time audio and video SDK built on WebRTC technology. Consequently, its compatibility depends on the browser’s support for WebRTC.

    ### Desktop browsers [#desktop-browsers]

    Agora Web SDK is well supported on popular desktop browsers such as Chrome, Firefox, Edge, and Safari. To ensure the best user experience, best practice is to use the latest version of each browser on the latest version of the operating system.

    ### Check browser compatibility [#check-browser-compatibility]

    The Agora Web SDK provides the `checkSystemRequirements` method to determine if the SDK can be used in the current browser.

    ```js
    const result = AgoraRTC.checkSystemRequirements();
    // result is true for support, false for non-support
    console.log(result);
    ```
