If you want to learn more about Arc browser developer tools and how they can benefit you, you’ve come to the right place.

Your web browser application is equally important as your IDE if you’re a website and web app developer. It allows you to visualize, improve, test, debug, and review your codes. Your browser should allow advanced developer integrations, extensions, and code optimization features.

So, if you’ve been using Google Chrome or Mozilla Firefox for website development and you’re looking for a change, check out Arc browser. I’ll cover its developer tools and capabilities so you can see if it fits your needs. Ready?

What Is Arc Browser Developer Mode?

Arc Developer Mode offers various tools for website and app development projects.

This mode transforms the selected tab entirely by adding new UI elements, assistive tools for website development, a full-length website address bar, a screenshotting tool, etc. It also automatically enables the JSON Formatter extension so you can review website codes efficiently.

Moreover, Arc browser includes a dedicated Developer mode for browser extensions. You can test your custom add-ons without switching to a different browser. You can load unpacked add-ons, pack them, and more.

Developer mode for extensions

In a nutshell, Development mode removes the bottlenecks of frontend development by covering all the necessary features in one app.

On a Mac computer, you can enjoy all the features of Arc browser developer tools. However, if you’re using a Windows 11 PC, the following functionalities won’t be available:

  • Full URL
  • Portrait Mode
  • Capture a Portion
  • Boost
  • Arc Max AI.

How To Enable Arc Browser Developer Tools in Mac

You must enable Developer Mode to get access to the tools for each tab individually:

  1. Click on the Site Settings icon in the URL Bar, located above the sidebar.

Standout Arc Browser Developer Features and Tools

Here are some must-have tools you should know about:

Full URL Address Bar

Developer Mode in Arc offers a full-size URL bar across the top of your window. This makes it easy to see long website addresses. Also, you can navigate complex URLs with ease. No more squinting or mistyping!

Full URL Address Bar

Capture in Portrait Mode

Arc lets you capture website screenshots in two ways in dev projects. The first one is the Capture in Portrait Mode which allows you to grab a full-page screenshot. It’s perfect for sharing website layouts or saving long articles for later.

Capture in Portrait Mode

Capture a Portion

You can also use the Capture a Portion feature. Simply select the area you want and Arc saves it as an image – ideal for grabbing code snippets or specific visuals.

Toggle Console

Do you want to see the code behind a website? Use the Toggle Console feature to bring up a developer console with website codes. It allows you to view error messages, run JavaScript code, and interact with the web page’s background code.

Toggle Console

Toggle Network Panel

Are you curious about how fast a page loads? The Toggle Network Panel displays information about all the files a website uses. It helps you to pinpoint the bottlenecks so you can optimize loading times.

Moreover, you can use this developer tool to get a sneak peek into competitors’ websites that load faster than yours and compare strategies.

Network Panel

Inspect Element

Do you ever wonder what font a website uses, or how to change a button color? Arc’s Inspect Element lets you hover over any part of a webpage to see the HTML and CSS code behind it. You can even make temporary changes to the code and see the effects live in the browser.

Inspect Element

Split View

For a truly immersive experience, you can use the Split View feature.

Split View

For example, in the following image, I’m reviewing the underlying code of the Google Maps app side by side with the Google Maps portal. This split view makes it easy to see how changes in the code translate to visual changes on the webpage.

Boost is a visual method to customize the graphical and textual website elements for multiple editions for fun or a client review. You can save the customized view of a website so you can share it with collaborators. However, the actual website won’t change.

Boost includes a smart color wheel so you can change the shades. For color editing, there are additional controls, like Invert lightness, Advanced color controls, and Reset to original colors. It also makes font customization easy. You can pick a typeface from 20 choices and edit the font Size and Case.

Arc Boost

To delete elements and content from a website for A/B testing purposes, you can use the Zap feature. It creates a visual and interactive layer on the existing website so you can remove things with a simple click.

Explain or Complete Codes With AI

If you’ve activated Arc Max you can use the Arc browser ChatGPT integration to ask questions. Also, you can use AI to write codes from scratch or auto-complete scripts you optimize in the Console, Network Panel, and Inspect Element.

For example, I’ve copied a short segment of the underlying HTML script for Google Maps.

Then, I used the Ask ChatGPT feature to learn more about it. I could see the Console, the visual website, and explanations.
