Extensions are software packages that allow users to personalize their Chrome browsing experience and development using web technologies (such as HTML, CSS, and JavaScript). These extensions can let you automate particular browser tasks, tweak current behaviors, and increase the usability of your product. Here are some of our picks for must-have chrome extensions for developers.

1. Window Resizer

This add-on resizes the browser window to simulate different resolutions. It is especially beneficial to web designers and developers since it allows them to test their layouts on various browser resolutions. The resolutions list is totally editable (you may add, delete, and reorder items). You may change the window’s width/height, location, icon (phone, tablet, laptop, desktop), and even whether the new dimensions should be applied to the full window or just the viewport. The extension also includes customizable global key shortcuts, the ability to export and import your preferences, and much more! There are currently 700,000+ active users with great reviews about the extension.

2. BrowserStack

BrowserStack is an Indian cloud web and mobile testing platform that allows developers to test their websites and mobile apps across a variety of browsers, operating systems, and real-world mobile devices. Live, App Live, Automate, and App Automate are their four main offerings.

In more than 135 countries, BrowserStack has over 25,000 paying clients and 2 million registered developers. Browserstack has a number of advantages, including no setup and no maintenance, which helps to speed up releases. SOC2 compliant, instant access to 3000+ browsers and actual iOS and Android devices.

3. Accessibility Insights for Web

Accessibility Insights is a plugin that assists developers in identifying and correcting accessibility issues in web apps and webpages. This is a go-to extension for developers to test the accessibility of their websites.

Two main situations are supported by the tool:

  1. FastPass is a simple two-step approach that takes less than five minutes to discover common, high-impact accessibility concerns.
    Automated checks: The tool tests for compliance with about 50 accessibility standards automatically.
    Tab stops: The tool includes clear instructions and visual aid to assist users to discover major keyboard accessibility issues such as missing tab stops, keyboard traps, and wrong tab sequence.
  2. Anyone with HTML abilities may use the assessment to see if a web app or website complies with the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA.
    Manual testing, for around 20 tests, the tool includes step-by-step instructions, examples, and how-to-fix assistance; many tests are “aided,” which means the program identifies the test instances or provides a visual aid.

4. Modheader

ModHeader is a lightweight, quick, and efficient application. With only a few clicks, you may activate or disable header modification. ModHeader allows you to limit your modifications to only one tab or a single website. It has a consistent 4+ star rating in the Chrome web store and is used by over 500,000 people.
