# Zoom Probe SDK for web

<!-- WARNING: THIS FILE WAS AUTOGENERATED! DO NOT EDIT! -->

Zoom Probe SDK for web is a tool that you can use to check if audio and video hardware, network, and Zoom infrastructure offers the best experience for your users. For example, integrate it into your solution to enable users to test their microphone, speaker, and video settings before joining a meeting or Video SDK session, or to investigate customer issues such as as blurry video, choppy audio, and poor network connectivity.

## Features
