With the widespread acceptance of web standards, and the resulting deprecation of browser prefixes, there has been a noticeable change in the browser market. Where once browser manufacturers would try to lure users in with promises of feature support, now the focus is on privacy, speed, and developer tools.
When it comes to web development, you should really be testing on every browser and device you can lay your hands on; you’re probably already doing so using an app like LambdaTest  , or BrowserStack  .
When quality assurance testing, you probably work by market share: starting with Safari  on mobile, Chrome  on desktop, and working your way down to Opera  and (if you’re a glutton for punishment) Yandax;  naturally, when testing, it’s the largest number of users that concerns us the most.
But before you reach the QA stage, there are a number of browsers designed to assist development. Browsers that offer tools, especially for front-end developers, that assist with code and speed up development. Here are the best browsers for web development in 2021:
1. LT Browser
LT Browser  is an app for web developers from LambdaTest. Like many of the apps in this class, it offers side-by-side comparisons of a site in different viewports. Additionally, LT Browser has a number of features that make it stand out.
As well as previewing web pages, LT Browser offers developer tools to rival Chrome, which is handy if you want to see how changes across different devices affect your Lighthouse scores. LT Browser also supports hot-reloading, which means when you make a change to your code, you don’t have to hit ‘refresh,’ the viewports simply reload — it’s surprising how much of a time-saver that simple addition is.
2. Firefox Developer
Polypane  is one of the new generation of web browsers that are firmly intended as development aids rather than browsers. Polypane allows you to compare different viewports and platforms by placing them side by side. Interactions like scrolling are synced.
Polypane takes a step further than many browser apps in this class by showing social media previews. It even has a suite of accessibility tools, including some handy color blindness simulators.
Blisk is awesome fun to play with and delivers a great preview of a responsive design. But be warned, synced viewports can be addictive, and it’s easy to line up browsers and become hypnotized by the synchronized movement; you’ll need a very large screen to get the most out of Blisk.
Sizzy also includes a very clever synchronized inspect tool, so you can focus on individual elements across different viewports. It’s an excellent option for debugging, particularly if you’re digging into someone else’s code.
Brave’s main benefit for developers is that it supports Chrome extensions while maintaining privacy — it can even access the Web using Tor if simple privacy mode isn’t enough for you. There are hundreds of useful Chrome extensions, and if you avoid Chrome due to privacy concerns, then Brave solves your problem.
Brave is also pioneering a new system for monetizing site revenue, allowing viewers to tip sites, and soon, to control how advertising revenue is distributed.
No matter the site you’re designing, it has to work well in Chrome, and no simulator is as good as the real thing.
In addition to being the benchmark for page rendering, Chrome developer tools are the simplest way to access your Lighthouse scores, which helps you track down issues that may be holding you back in Google’s search results.
