Important Asset, Network, and Resource Info
When loading a web page, it usually requires additional content in the form of fonts, scripts, graphics, and other files. These tools can assist developers in inspecting the website’s loaded resources in a three-structure listing.
Developers can use these to investigate network users’ data, such as debug time, HTTP headers received or delivered, and bandwidth usage.
Auditing and Profiling
Profiling allows users to collect data about their website’s performance. Developers can use this information to learn how to improve their websites. However, by analyzing a page, the auditing tools will provide developers with advice on improving responsiveness and reducing load time for optimization.
Browsers’ timeline features can offer a record of the time it takes to render pages, events that occur, and memory use. This functionality is critical for your web application’s optimization.
Plugin Support and Extensions
The majority of modern web browsers support extensions and plugins that add additional functionality. These plugins are simple to use and provide a wide range of functionality and capabilities.
