Web developers use web development tools to test and debug code. Unlike web builders, web development tools don’t help with webpage creation. They are better suited to testing the user interface of websites and web applications. Many web browsers including Google, Bing, Opera, Mozilla Firefox and Internet Explorers offer web development tools as built-in features or add-ons. These don’t require additional configurations or modules.
Web development software allows developers to inspect resources available on web pages. Users can view information about loading time, bandwidth usage, sent & received HTTP headers, and other network usage data.
Developers use web development tools to capture information about a web application’s performance. They offer auditing features that analyze web pages and provide suggestions on how to increase responsiveness while reducing load times. Modern web developer tools support plugins and extensions to augment functionality.
