What are Chrome Developer Tools

Developers are busy people but they sometimes use tools that make their job easier.

One such indispensable tool is Chrome Developer Tools.

With it, they provide top-notch and quality services.

How to Use Chrome Developer Tools The Lighthouse feature can be used to improve SEO

Chrome Developer Tools have several useful features and troubleshooting extensions whose interfaces are multifunctional.

Before any Chrome Developer Tool is approved and accepted for use, it must be sanctioned by reputable Developers worldwide.

One of the features that makes DevTools appealing to Developers worldwide is its amazing debugging extension for all browsers.

The Chrome DevTools are easy to use although you need to become familiar with its functionality to maximize its usage.

You can easily solve any problem you encounter while surfing through a website.

How is that made possible?

All you need to do is use the error console from the website as well as the monitoring features to activate the corresponding extension. 

Chrome DevTools also displays a front-end loophole that allows you to keep track of how the website looks on various platforms like mobile devices or computer monitors.

With Chrome DevTools, you can do website real-time editing on:

  • HTML
  • JavaScript
  • CSS

Once you edit a website, you can view the changes almost immediately though the changes may not change the website permanently. 

Because each correction is made on the source code, the results are temporarily displayed, and thus you may not be able to see the adjustments for some time.

This allows you, the user, to come up with how to improve the speed at which your website loads and it also fixes bugs easily.

Developers use Chrome Developers Tools to mainly customize applications that use the browsers to:

  • Solve any problems with the user interface 
  • Solve any bug issues with Javascript Code
  • Improve your codingOptimize 

To access Chrome DevTools, right-click any part of the page and select inspect elements from the menu options.

Next, select tools, then on the top-right menu options, choose developer tools.

Almost every internet user has Google Chrome, and the same is true for Developers too.

These Chrome Developer Extensions can significantly improve your work through effective testing, development, and debugging of any site through your Chrome browser. 

Even if you are familiar with Chrome already, you need to research these additional tips and tricks to boost your productivity.

Chrome has an experimental version called Chrome Canary.

This experimental version is a viable alternative for Developers who wish to use the limited version of DevTool.

The Chrome Canary is regularly updated to include recently added features.

Eye Dropper

This is similar to website fonts, but in addition, it enables you to know the color codes displayed on a website page.

You can quickly play around a webpage and get any specific colors with Eye Dropper.

All you have to do is click the color on the webpage and it will automatically be copied to your clipboard for easy access. 

You can access your history for web pages you can’t remember, and view their RGB values and hex values with this tool.

Eye Dropper for Chromium is also available, and it has other features you can use to dive into the CSS of the website.

CSS Viewer

CSS Viewer is a simple and handy CSS property viewer you can use to speedily identify the major CSS properties on a webpage. 

A popup window on your computer displays the data at any point your mouse is on the web page once you select the tool.

It is an open-source tool that enables you to find the source code on GitHub for free.

It also secures your privacy as it does not collect or transmit your private data despite requiring access to your history and web data.

So your data is safe, lucky you!

Clear Cache

Clear Cache is the easiest way to clear your cache by just a single click on your keyboard or just a button.

Benjamin Bojko created this means of clearing all your browsing data at a glance.

There are no confirmation dialogs, pop-ups, or anything else that can slow down your clearing process. 

You can also customize the amount of data that gets cleared from the following locations: App Cache, Cache, Cookies, Local Storage, File Systems, Form Data, History, Indexed DB, Plugin Data, Downloads, Passwords, and WebSQL. 

Although cookies are beneficial to some frequented domains even if you hate cookies, you can also customize the domain cookies that will be deleted and left uneaten.

You can discover all the technologies a website is using within seconds of looking at the site through this amazing Developer tool. 

You also get to understand what a competitor is searching for or reading by applying Wappalyzer.

We’re personally inquisitive about the technology our favorite websites use, thus we frequently check Wappalyzer while surfing the internet.

You can detect the JavaScript libraries a site uses, the e-commerce platform they subscribe to, their CMS, Analytics, frameworks, PaaS, and other browser-related details through this Chrome Developer Tool.

You don’t have to sign up or input your details to use the free version.

All you need to do is to install and check out the websites you’re inquisitive about. 

Wappalyzer also has a pro version that provides the contact information of any company you wish to search for.  

Comparison of free and paid Chrome Developer Tools

Comparison of free and paid Chrome Developer Tools

While there is nothing wrong with using the free Chrome Developer Tools, it is a personal decision each one must make based on what task they need to execute.

However, let’s compare both and see which one will be most beneficial in the long run:


One reason why most people choose free Chrome Developer Tools over the paid versions is that they cost virtually nothing to use them. 

Unlike the paid versions where you have to get our credit card details ready before you can use them, all you have to do with the free version is get a credible link and just start using them.

So in terms of cost, it is profitable to use the free version.


As expected, free versions will have fewer features as compared to using paid versions of Chrome Developer Tools.

In most cases, they don’t just have more features, these features are also user-friendly.

Some Chrome Developer Tools offer tutorial videos where new users can get visual help on how to navigate through its amazing features.

So, in terms of features, it pays to use paid Chrome Developer Tools.


Most paid DevTools are versions that are compatible with various electronic and mobile devices.

We shouldn’t expect anything below that for the money we paid.

This is unlike free versions that may have just one version.

So in terms of availability on several versions, it is better to use pad Chrome Developer Tools.  

Pros and Cons of Using Free or Paid Chrome Developer Tools

  • It often uses lots of CPU space and RAM
  • In most cases, the extension elements cannot be directly clicked on to scroll the screen either up or down for ease of access. 
  • The command code community is too large, hence it is not easy to avoid getting stuck on large browser pages Focusing on the screen during these moments is not easy
  • Some of the Chrome Developer Tools have a rather steep or abrupt learning procedure
  • A lack of an element that lets all users edit their jobs directly from the console – Some are trying in this aspect but could be better

This function would have been great for creating multi-functional programs.
