Most browsers you think are different are not really built from scratch. They simply take Chromium, build on top of it, add their own design, features, and branding, then ship it as their own browser.
Chromium is the open-source engine that actually powers the web. It’s the part that understands HTML, renders pages, runs JavaScript, manages tabs, and enforces security. In simple terms, it’s the engine under the hood, not the paint job.
So when you install Chrome, Edge, Brave, Opera, Vivaldi, Arc, or Samsung Internet, you’re not getting completely different technology. You’re mostly getting the same core engine with different skins and extra features layered on top.
Chrome is Google’s flavor.
Edge is Microsoft’s flavor.
Brave adds privacy tools and ad blocking.
Opera adds built-in extras.
But underneath is the Same Chromium. Same Blink engine. Same behavior.
It’s like ten car brands using the exact same engine but changing the body and dashboard. They look different, but they drive almost the same.
That’s why a site that works on Chrome almost always works on Edge or Brave too; they’re literally speaking the same language internally.
The only real exceptions are browsers like Firefox (Gecko engine) and Safari (WebKit). Those are built independently from the ground up.
Apparently it’s all chromium
