While reading this post, you may want a starting point to explore Chrome extensions so here you go the Chrome Web Store.

In this ultimate guide, I’ll walk through the tools that have consistently improved my workflow.

1. Simple Data Layer Viewer

Whenever I work with Google Tag Manager or analytics implementations, Simple Data Layer Viewer makes my life easier. It allows me to instantly inspect the data layer on any webpage and view pushed events in a structured format. Instead of digging through console logs manually, I can quickly verify whether events are firing correctly and whether the data structure is accurate.

The best part is that a new Live Data Layer tab gets added to your developer toolbar. This tab can be docked to the bottom or right side of the browser window, allowing real-time visibility into data layer events as they fire.

2. Similarweb – Website Traffic & SEO Checker

If you’re curious about how a website is performing online, Similarweb – Website Traffic & SEO Checker makes it really easy to get quick insights. Once this extension is installed, you can open any site and instantly see estimated traffic stats, engagement metrics, traffic sources, and top keywords. It gives you a quick snapshot without needing to log into a full analytics platform.

If you’re into SEO or content strategy, this tool can be surprisingly insightful.

3. JSON Beautifier and Editor

JSON Beautifier and Editor transforms API responses into a clean, readable structure. It supports collapsible tree views, inline editing, and syntax validation. This makes debugging REST and GraphQL responses significantly easier. Instead of copying JSON into external tools, responses can be inspected directly within the browser.

4. JSONVue

JSONVue automatically formats JSON responses in the browser and presents them in an organized tree layout. Nested objects and arrays become easier to navigate and verify. For API-heavy applications, this improves debugging clarity and reduces visual clutter.

5. JSON Viewer

JSON Viewer extension helps easily read and analyze JSON or JSONP responses directly in the browser. JSON Viewer automatically formats this data into a clean, structured tree view with syntax highlighting, making keys, values, arrays, and objects easier to understand. The extension includes multiple themes for customization, a built-in search feature to quickly locate specific keys or values, and options to toggle between raw and formatted JSON views.

Basically, JSONVue fulfills the basic requirement if you simply want to view the response in a formatted JSON structure. On the other hand, JSON Viewer provides a few additional features through a dedicated panel on the right side of the browser. Features like search and fold/unfold all toggles make navigating large JSON responses much easier. Because of these capabilities, JSON Viewer is often my preferred choice when working with complex API responses.

Try these extensions by browsing a dummy JSON URL and see which one best fits in your use case.

6. Lorem Ipsum Generator

Lorem Ipsum Generator is a lightweight Chrome extension that helps developers, designers, and content creators quickly generate placeholder text directly in the browser. Instead of visiting external websites to copy dummy content, the extension lets you instantly create customizable Lorem Ipsum text. You can choose the format – paragraphs, words, bytes, sentences, or lists – and even control the length of the generated text.

7. Window Resizer

Window Resizer switches between predefined viewport sizes with a single click. Responsive layouts can be tested across desktop, tablet, and mobile breakpoints efficiently. This reduces manual resizing and improves validation speed for responsive designs.

8. CSS Viewer for Google Chrome

CSS Viewer for Google Chrome displays CSS properties such as margin, padding, font size, and positioning on hover. It enables quick visual inspection without navigating deep into Chrome Dev Tools panels. UI debugging becomes faster and more focused.

9. WhatFont

WhatFont is a popular Chrome extension that allows developers and designers to quickly identify the fonts used on any website without manually inspecting CSS in browser developer tools. Once activated, the extension lets you simply hover over any text on a webpage to instantly see the font name and clicking on the text reveals additional details such as font family, size, weight, style, and color.

10. Color Picker – Eyedropper Tool

Color Picker Eyedropper Tool is a lightweight extension that allows developers and designers to quickly capture colors from any webpage. Using the built-in eyedropper tool, users can pick colors directly from screen elements and instantly retrieve the corresponding HEX, RGB, or HSL color codes.

The extension also provides an interactive color picker that lets users fine-tune selected colors and export them for use in CSS, design tools, or style guides.

11. Lighthouse

Lighthouse auditing tool helps developers evaluate the quality of modern web applications. It runs automated tests on a webpage and generates detailed reports covering performance, accessibility, SEO and best practices. Developers can quickly identify issues such as slow loading resources, unused JavaScript, accessibility gaps, or poor caching strategies.

By using Lighthouse during development, teams can continuously monitor and improve the overall performance and reliability of web applications.

12. Fake Filler

Fake Filler extension automatically populate web forms with realistic dummy data, making it extremely useful for developers and QA testers during development and testing. Instead of manually entering values into multiple input fields, the extension can instantly fill forms with sample names, emails, phone numbers, addresses, and other common data types with just single click. You can even fill individual fields as well.

13. JavaScript Errors Notifier

JavaScript Errors Notifier alerts users when runtime errors occur on a page. Silent failures become visible immediately. Early detection improves debugging speed and application stability.

14. Text Case Converter

If you ever find yourself constantly switching text between different cases while working in the browser, Text Case Converter can save you a lot of time. I like using it when I need to quickly convert text to UPPERCASE, lowercase, Title Case, Sentence case, or even alternating case without opening another editor.

15. Time Zone Converter – Savvy Time

Time Zone Converter – Savvy Time simplifies global scheduling by comparing multiple time zones instantly. Deployment coordination and meeting planning become more reliable. It reduces errors caused by time differences in distributed teams.

16. Sitecore Extensions

If you work with Sitecore regularly, you know how many small repetitive tasks are involved in navigating the CMS. Sitecore Extensions includes a set of simple but very useful enhancements that make those everyday tasks much easier. When using it you can quickly access helpful shortcuts, view extra item details, and move around the Sitecore interface more efficiently without digging through multiple menus.

I’ve found it especially handy when inspecting items or jumping between content quickly during development. It’s one of those small tools that quietly improves your workflow and saves time throughout the day.

17. React Developer Tools

If you work with React, the React Developer Tools is one of the best chrome extension. Once installed, it adds dedicated Components and Profiler tabs inside Chrome Dev Tools, letting you inspect the React component tree in real time. I often use it to see how props and state are flowing through components, which makes debugging UI issues much easier.

You can also profile component renders to understand what’s causing unnecessary re-renders. When building or debugging React apps, this tool gives you visibility into your component structure that regular DevTools simply can’t provide.

18. Lytics Dev Tools

Lytics Dev Tools provides insight into audience segmentation and identity resolution for personalization-driven platforms. It lets you inspect how the Lytics Web SDK is behaving on a page and view the events, identities, and data being sent to the platform in real time. I find it especially helpful when validating whether tracking calls and API requests are firing correctly.

Instead of digging through network logs or console output, you get a clearer view of what’s happening behind the scenes. If you’re integrating or troubleshooting Lytics, this tool can save you a lot of debugging time.

19. Wappalyzer – Technology Profiler

Whenever I land on a website and wonder what tech stack is this site using, Wappalyzer is usually the first tool I open. This Chrome extension quickly analyzes a webpage and shows you the technologies behind it – things like CMS platforms, JavaScript frameworks, analytics tools, CDNs, and hosting providers.

Instead of digging through page source or network requests, you get a clean snapshot of the tech stack in seconds. If you’re a developer who likes to understand how modern websites are built, this tool is incredibly handy.

20. BuiltWith Technology Profiler

BuiltWith Technology Profiler is another Chrome extension that gives you detailed insights into the technology stack behind any website. At first glance, it can feel a bit overwhelming because it shows so much information all at once. There’s nothing wrong with that – it’s great if you want a deep dive – but personally I use Wappalyzer mostly.

With just one click, it gives me a clean, high-level view of the tech stack, which is perfect when I just want to understand the main technologies without digging into every detail.

Final Thought

Choosing the best chrome extension for web developer workflow is not about installing every available tool. It’s about building a practical, focused toolkit that supports analytics validation, API debugging, responsive testing, UI accuracy, and performance optimization.

The extensions covered here address real development challenges. When used strategically, they reduce repetitive tasks, improve debugging clarity, and enhance overall efficiency. With the right setup, Chrome becomes more than a browser – it becomes a fully optimized development environment.

Sitecore Security Bulletins are notifications issued by Sitecore to inform customers about new security vulnerabilities and patches related to Sitecore software. Subscribing to Sitecore Security Bulletins is highly beneficial for several reasons:

• Stay Informed: You’ll receive timely notifications about new security vulnerabilities and patches, helping you keep your Sitecore environment secure
• Proactive Protection: By staying updated, you can apply security updates promptly, reducing the risk of exploitation by malicious actors
• Compliance: Regular updates ensure that your system complies with the latest security standards and best practices
• Peace of Mind: Knowing that you are aware of and addressing potential security issues can provide peace of mind, allowing you to focus on other aspects of your business

You can find the Security Bulletins on Sitecore KB home page as given below and filter the result as per your software version

https://support.sitecore.com/kb

However, this method is not efficient because you constantly need to monitor the page. Instead, subscribe to Security Bulletins as described in this KB article:

https://support.sitecore.com/kb?id=kb_article_view&sysparm_article=KB1000489

As soon as a new security patch is released, you’ll be notified. Keep your Sitecore environment safe.

Finally we raised a support ticket with Sitecore and found that this issue seems to be due to security fixes in the cumulative hotfix. You can find more detail on this issue in this Sitecore KB article:

https://support.sitecore.com/kb?id=kb_article_view&sysparm_article=KB1003018#FAQ

As per recommendation from Sitecore support team, we applied below patch configuration on CM server:

<?xml version="1.0" ?>
<configuration xmlns:role="http://www.sitecore.net/xmlconfig/role/"
xmlns:security="http://www.sitecore.net/xmlconfig/security/"
xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
        <reflection role:require="ContentManagement or Standalone">
            <allowedMethods>
                <descriptor type="ProjectName.Sites.SitecoreCode.Fields.CustomFieldName"
                methodName="Add" assemblyName="ProjectName.Sites.SitecoreCode" />
            </allowedMethods>
        </reflection>
    </sitecore>
</configuration>

<?xml version="1.0" ?>
<configuration xmlns:role="http://www.sitecore.net/xmlconfig/role/"
xmlns:security="http://www.sitecore.net/xmlconfig/security/"
xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
        <reflection role:require="ContentManagement or Standalone">
            <allowedMethods>
                <descriptor type="ProjectName.Sites.SitecoreCode.Fields.CustomFieldName"
                methodName="Add" assemblyName="ProjectName.Sites.SitecoreCode" />
            </allowedMethods>
        </reflection>
    </sitecore>
</configuration>

The related XAML controls are not used on CDs since hotfix contains instructions to disable the related handler so we applied this patch only on CM server. Hope this helps!
