To test web applications and for front-end web development. It enables us to test, understand what the application will look like on devices, and debug. As it's already built into the Chrome browser, it's readily available and easy to use to enhance the performance of any website.
  • User friendly to navigate around
  • Debugging
  • Can test Java script codes
  • Ability to export reports
  • Documents are too technical is areas
  • Can't customise to a full extent
It is well suited for web application development and mobiles, enhancing the performance due to functionality such as the inspection of web elements, debugging Java script codes, and changing front-end frameworks. The tool is very comprehensive so not sure of any scenarios where it is less appropriate.

There are multiple use cases that our organization fulfills with the help of DevTools. We have been regularly using it to check and evaluate our website's performance and basis the reports several performances improvement activities are carried out. Also, we use it to debug the HTML and CSS codes that the developers type out.
  • Debug
  • Performance Report
  • Element Tab
  • Interface
  • Summary for layman
  • Business metrics

Chrome Dev Tools help me debug my websites, find css classes to change styles on my development websites, and also use it to test various different view ports , device or what the website looks like on certain mobiles. It also has the Lighthouse functionality which aids in my SEO activities and determining the performance of the website such as how the page assets load and page load speeds
  • inspect elements by right clicking directly on the element on the website
  • determine page speeds and optimization advise for SEO using the lighthouse
  • great for seeing what websites will look like on mobile
  • I don't really like the UI and visual aspect of the tool, I prefer a dark theme
  • Sometimes it glitches after editing a style, and then I can't edit other styles until reload
Chrome DevTools is best for web developers, front end designers and anyone who is developing a website. It's great for SEO optimization to get advice and info on the assets and resources the website uses and how it performs. Also great for checking if your website is mobile friendly. Great for debugging

When developing websites, I use a lot the network tab and JS debugging The masterpiece is the possibility to change CSS live to adjust the rendering I recently use webauthn to debug SSO implementation Chrome DevTools is also powerful to optimize the existing sites to gain reliability and simplicity The DOM exploration can be really difficult manually and this is just the only way to get into it
  • DOM Exploration
  • Live CSS debugging
  • Resources downloading report
  • Responsive website debugging
  • Animation tools can be easily improved
  • A new tool to export reportings in external DB or in cloud
  • A new tool to follow an external logs like ASPX or Python
Chrome DevTools is really well suited for debugging frontend HTML/CSS. It helps to give a focussed view for developers and parts they want to test, correct, or play with But Chrome DevTools is not appropriate for backend debugging with REST web services where Postman is a better tool Introduce Postman features in Chrome DevTools could be great

The Chrome DevTools is very useful for debugging front-end projects. In this, we have a lot of options to check application performance. We can see the cookie and stored values. We can see network call status and response in the network tab. We can run the javascript in the console of the developer tool. We can set breakpoints or debugger points to check errors in the script. We can see all HTML element structure in the Elements tab. We can test the performance of the application using the performance insights tool. We recently used this tool to check application timeout using the console tab.
  • It is very useful for front end developers to test JavaScript code
  • DevTools given flexibility to check API response time(load time)
  • It is used to check DOM element structure and we can change element structure for testing purposes.
  • Is used to test and modify the CSS of Page elements
  • Chrome DevTools need to provide options to download application performance reports
  • They need to provide some type of editor for developers to write code on the fly.
  • They need to give security information in the console to developers
  • Compared to other tools, Chrome DevTools are very useful but if they provide more options like code editors, that will be helpful.
1. It is very useful for debugging javascript. 2. Check CSS style. 3. We can check element structure. 4. It is very useful for network call checking. 5. We can check the responsiveness of websites like mobile, and tab simulators 6. This tool is very useful for traffic reports 7. We can check the score of the accessibility report.

Very useful for debugging and troubleshooting web pages. We also use it to measure component loading performance and visualization tests at different resolutions. We recently used this tool to identify timeout errors in the ajax request of a component on the page, which was derived from the security rules applied in Application Gateway in the Cloud, and adjust the parameters
  • Page load time graph, detailing the required load time for each component.
  • Analysis of sent and return content
  • Security reporting of in-memory components such as secure cookies and cached data.
  • PWA configuration validation
  • A resource to work with secure HTTPS content, decrypting the traffic data, as a sniffer would.
  • An online editor for page elements is very useful, but it should always be used with a large monitor, above 15".
  • Exporting or printing the analysis reports would be very helpful
A great support tool for quick analysis and on-the-fly troubleshooting, but it should be used by technical personnel with good programming skills. Very practical for testing visual changes in the page's source code, and measuring the performance and security of all components used on the website, regardless of the technology adopted as the back-end.

The Chrome DevTools are a complete set of resources for creating websites and online applications. To help developers create better, quicker, and more responsive websites, Google has integrated a development tool straight into the Chrome browser. We use a wide variety of frontend technology stacks for our websites, from the relatively dated to the cutting edge. Chrome's DevTools are used to ensure webpages are compatible with older browsers.
  • Running JavaScript on the fly is possible via the console.
  • Method for determining where a network is slowing down.
  • Take a look at how a page is structured by using the DOM in Inspect.
  • High demands on both RAM and processing power.
  • The steepness of the learning curve.
  • The Chrome DevTool needs to provide an editing panel in addition to the console. Creating functions that span many lines would be helpful.
All-in-one platform for creating websites. It's simple to inspect the dom structure and source code, which facilitates JavaScript code debugging. Modifying the CSS and stylesheets on the fly is a breeze. To aid with performance troubleshooting, the network tab lists each HTTP request in great detail. Refactoring and improving legacy web applications by integrating modern front-end frameworks like React.

I use Chrome DevTools inspector almost every day to source code, or to see how a website looks on mobile. I also use Page Speed Insights on a very regular basis to check site performance and improve scores. In WordPress, I also use a plug-in to use speed insights to check page speed scores within WordPress itself. I only scratch the surface of Chrome DevTools and honestly couldn't work without them. They are completely indispensable to my workflow.
  • Identify code
  • Previews on different devices
  • Performance of webpage
  • There should be a "Chrome DevTools for non-developers" course - sometimes the documentation is very technical.
It is beyond useful within Chrome itself, to identify pieces of code and preview sites on different devices. Any and almost all job that revolves around website or content creation needs should use DevTools. It's probably less well suited for "amateur" website builders, but in order to QA work, designers, developers, SEO analysts, and writers can all benefit from using these tools.

Chrome Developer Tools is a comprehensive toolkit for developers which helps them in developing web apps. Dev tool is built directly into the Chrome browser and lets the developer edit web pages in real-time, debug problems quickly, and build better, faster, and more responsive websites. Our websites are a mix of older and newer frontend technology stacks. Chrome dev tools are used by the developers for testing the websites for backward compatibility. For mobile app development also the emulators are handy. Developers use it to identify where resources are loading from, performance, and configuration issues. We also use it to interact directly with the JavaScript console.

Overall it is an excellent tool for frontend web developers.
  • Provides tools for observing network and application performance, and way to simulate varying network speeds.
  • The console can be used for ad-hoc JavaScript running.
  • Performance analysis tool for finding network bottlenecks.
  • Inspect tool to view the DOM structure of the webpage.
  • Emulator for different screens (mobile , iPad, etc).
  • High memory and CPU usage at times
  • Learning curve is a bit steep
  • Apart from the console, the Chrome dev tool should provide a panel with the editor. It would be useful to write multi-line functions.
  • No other complaints. Pretty much comprehensive set of tools
Comprehensive web development tool. It is easy to see the source code and dom structure which helps in debugging JavaScript code. Easy to manipulate the styles and CSS on the fly. The network tab provides detailed information about the HTTP requests which helps in performance debugging. Making changes to existing old stack websites and enhancements with new frontend frameworks like react.

Used to detect and find root cause of html/css issues as well as javascript debugging when there are unexpected results in a specific scenario. Chrome DevTools helps to see the stack trace at any execution point in scripting language.
  • Show current html DOM objects
  • Display CSS properties in an accurate way
  • Emulate mobile devices
  • Limited customasation
  • Google tracking
  • High memory and CPU usage
Works Well with desktop websites.
Well suited for jQuery websites.
Luckily Chrome Dev Tools is faster than firebug and it is not an extension but part of the browser which makes it very useful.
Pretty printing is another feature than Chrome Dev Tools does incredibly well.
Chrome Dev tools could improve the console interface to allow multi-line scripts as smoothly as Firebug.

Chrome DevTools is being used by a few development departments in the organization. In our team, we used it for a few purposes:
1. To examine the DOM of a web app.
2. Aid development of web apps: check the API requests and response.
3. Performance analysis: use the performance tool to analyze the bottleneck of the app.
  • The "inspect" tool is very convenient. It can show the DOM structure interactively.
  • The performance analysis tool is very comprehensive. Easy to spot bottleneck.
  • The console is very handy for ad-hoc JavaScript running.
  • In the "Element" section, when mouse-over an element, the corresponding part in the web will be highlighted. It is sometimes annoying as the mouse moves around.
Chrome DevTools is excellent for a few scenarios:
1. Web development
During web development, the "Elements" tool is very good for inspecting the frontend appearance of the web site. The "Network" tool is very good for inspecting whether the requests and responses go as expected.

2. Monitoring the behaviour and performance after a web app is created
The "Performance" tool can show the behaviour and bottleneck very easily.

We use Chrome DevTools for front-end development and debugging. Everyone on my team uses it, and I would suspect others in my department use it as well, probably anyone using Chrome as their main browser. The DevTools allow us to inspect our sites and find problems with HTML, CSS, and JavaScript.
  • Inspect front-end code.
  • Find and debug issues.
  • Apply changes in the browser for testing.
  • Test responsive designs at various device resolutions.
  • Test page speed and performance.
  • Test various network situations (e.g. low/no internet connection).
  • Improved screenshot support.
  • Quicker access to common testing settings (e.g. disabling JavaScript).
  • Improved CSS tools.
Chrome DevTools (or something similar) is almost essential for front-end development. It allows for inspection of HTML, CSS, and JavaScript, and allows you to debug issues right in the browser. DevTools also enable you to apply changes within the browser and see the changes immediately without accessing the actual code. In addition, it works very well at testing service workers, viewing and testing page performance, testing different network speeds, and testing responsive sites at different resolutions.

All of the full stack developers use Dev Tools in Chrome for identifying and diagnosing weird problems with the web sites. We use it to identify where resources are loading from, track down configuration issues, and interpret the performance of loading pages. We also use it to interact directly with the JavaScript console.
  • Being integrated with the browser, DevTools lets me access elements of the loaded page easily and directly. I can see what my page looks like in the browser while I fiddle with various parameters directly in the page through DevTools.
  • DevTools lets me identify all of the artifacts that are loaded by the current page (images, scripts, media, etc.). I can easily determine if some third party package is getting in the way of my own content loading correctly.
  • DevTools gives me direct access to the JavaScript console so I can run JS methods directly. This lets me visibly see how certain interactions can look and feel to the user.
  • The Network tab gives me visibility into what the page is doing "behind the scenes". This is very helpful when working with dynamic content as I can see where and how things are loaded.
  • While Chrome DevTools has a good REST sniffer, allowing me to see REST requests that my web app is making, it does not provide a general interface for constructing REST requests. I would like to see some functionality similar to Postman integrated with DevTools.
  • While the Security tab allows visibility of the certificate associated with the site itself, it could present more information about the certificate and protocols in use. I would like to see full details of the entire certificate chain.
  • Some items (such as Network conditions, Sensors, etc.) in the More Tools menu could be expanded upon.
  • I would like to be able to connect to some external tools. It would be nice, for example, to be able to easily see traceroute (or mtr) output directly in the interface. I realize that some of these capabilities require elevated privileges, but that could probably be worked around be forking off a terminal instance to run the tool with Sudo or something similar.
Given that DevTools is always available, it is well suited to impromptu inspections and investigations. It is less useful for automated testing where running Chrome may be more difficult (in a headless environment, for example). It would be nice to see some type of headless interface to DevTools where it could be accessed via some type of external API.

I used Chrome DevTools pretty regularly to sneak a look at the code of a webpage, either to do web development, or more likely nowadays, because I'm doing some data analysis and need to figure out how to scrape the data off the page and into R. Because it's baked right into Chrome, my regular browser, it's only ever a quick whack of F12 away.
  • The selection widget is particularly handy--I can quickly and easily see how an element on a page fits in the page's structure
  • Being able to edit CSS rules on the fly is great--that way I can see what's actually going to happen.
  • It's also nice to be able to poke around in the Computed tab and see how an element's box model attributes are currently assigned and what will happen if I adjust, for example, the padding.
  • I really miss Firebug's box model tools, which worked a bit more intuitively.
  • The Console is handy, but can be hard to work with.
  • I really wish there were a few more tools for outlining block elements and a color picker.
If Chrome is your main browser (and seriously, what else are you going to use?), and you need to look at the source code of a website for any reason, you should be using DevTools. It's the most efficient way to get the most info, and a great way to dig into the back end of your site, the CSS, the javascript, general performance, etc.

Web application testing and troubleshooting are one of the most time-consuming areas of a software engineer's tasks and the availability of reliable and comprehensive tools to facilitate this important job is critical. Chrome DevTools is an important tool in any developer's arsenal and it has been one of my long-time go-tos for this purpose. DevTools can reveal important information to you about errors your code is throwing, the state of your document model (the elements of your web page and how they are laid out) and the factors that are affecting the performance of your application. In my organization, we use Chrome DevTools across our engineering team to troubleshoot and test all of our front-end application code.
  • Excellent DOM inspection tool that gives you important insights into your styles and element behavior, and allows you to make changes in-line that can show you what impact they will have if applied to your code.
  • Outstanding tools for observing network and application performance, including throttling to simulate varying network speeds.
  • A fantastic device emulator that allows you to view how your pages and application views will appear when viewed on a wide array of mobile devices such as tablets and smartphones.
  • Debugging tools that give you the power to insert breakpoints to pause code execution and view the value of your code variables.
  • It could really use an easier way to separate the kind of errors being logged to the console, such as network, security and CSS errors. This becomes a more acute problem when you consider that Firefox does have this feature.
  • Unlike the Firefox and Edge dev tools, it forces you to click into a line item for network request in order to view the details of that request.
  • Its performance measuring tool could stand to catch up to that of Microsoft Edge, which currently displays visualizations that are a bit easier to review.
If you are developing, testing or debugging web applications, then it would be hard to make a case against relying heavily on Chrome DevTools to help you along. It has kept pace with the development of other browser tools with similar features (Firefox and Microsoft Edge come to mind) and while it doesn't stand out as especially strong compared with the competition it remains a popular choice among developers and will likely be so for the foreseeable future. While it is a good idea to test across browsers and make use of their development tools as well, it is a strong choice for your default option.

It works best as a tool for developers and designers building pages through direct development of HTML, CSS, and JavaScript, or through a CMS such as WordPress or Drupal. It is also useful for theme design for tools such as WordPress or Drupal. It is probably best avoided by those relying on visual drag-and-drop style platforms for web site building, such as Squarespace or Wix, since it is likely to offer more confusion than help.

As our Company has many departments, Chrome DevTools are only being used by the web development teams. We have lot of development teams for different projects we generally use Chrome DevTools for debugging, better analysis of code or when we get stuck somewhere. As per the business problems it let us fix different JavaScript issues and suggests how to optimise the code that is running on the PCs as well as mobile phones.
  • First is the Debugging capabilities of Chrome DevTool i.e. very impressive you can set the break points where you think error might exist or you can simply go step by step until you encounter the issue.
  • Second the capability of simulating mobile devices with device mode in Chrome DevTools - It is also great feature in which one can see where the network is throttling one can check for responsiveness of the view port on the mobile device.
  • To analyse network performance - Generally it is a great feature to have because it lets us know which file it may be and if it's JS or CSS that is taking time to load or taking more resources then one can focus on them to make it light weight.
  • As of now I don't have any issue with Chrome DevTool, it is best and improving day by day but if they can they should improve the interface so that switching between different tabs becomes easy.
Chrome DevTools is well-suited for debugging JS errors, for looking on network performance, simulating mobile devices, and remotely debugging mobile web.
