Edge is Microsoft's attempt to stay relevant after all the years of pain and heartache that came from Internet Explorer.

Their large investment into OpenAI has enabled them to pull in some AI into the browser (branded as Copilot), though it's more just a wrapper for ChatGPT with various pre-built functions.

While Edge is built on Chromium (like many of the best browsers on the makes), they are one of the only browsers (aside from Arc) that have managed to exist without taking that sweet sweet money from Google.

Edge makes money by promoting their many Microsoft products, making them work more seamlessly in the browser where possible.

While Microsoft has tried so hard to get back the marketshare they once had and have since lost, Edge still feels a bit dated in their UI/UX, and their unique functionality isn't all that great unless you're an avid Microsoft 365 user.

That said, if you're on this site and doing software research, you're more likely using Google Workspace and Gmail, and there are much better browser options on the market, even if you're a Windows user, as even Arc is now on Windows.

Chromium is something you're likely using right now without even realizing it. Are you using Arc Browser, Chrome, Brave, or even Microsoft Edge right now? Okay, then you're using Chromium.

You know those extensions you have in the top-right corner? Yep, those are Chromium extensions (often referred to as "Chrome Extensions"). Little do people know, Google built an open-source foundation to the browser, for which most of the top browsers on the market use as their foundation.

I mean you're not exactly looking at traditional competition here, but Apple does use a competing standard called Webkit. So if you're using Safari on your computer, that's running on Webkit instead of Chromium.

The super interesting part here though is if you're using iOS, any browser you're using is actually built atop Webkit—even Google Chrome. Apple requires Webkit be used on iOS regardless.

Why exactly? Well, Google pays Apple some $20bn per year to be the default search engine in Safari, so holding onto Webkit on iOS and iPad is probably one of their leverage points:

“At-least we still own the foundation of the browser for our products!”
-Apple (probably) 🤷

This genuinely probably doesn't mean much to you, but you're probably using Chromium and you probably don't care.

Just know that it makes for switching between Chromium-based browsers far easier—from transferring bookmarks, to extensions, and everything inbetween.
