Most people use a Chromium-based browser without realising it. Chrome, Edge, Brave, Vivaldi and Opera all run on the same open-source engine. The rendering, the extension support, the developer tools: largely identical. What differs is everything happening behind the scenes with your data.
This guide looks at the main Chromium browsers side by side on privacy, explains what each one actually does with your information, and makes the case for why Brave is the one worth switching to if privacy matters to you.
What is Chromium and why does it matter?
Chromium is the open-source browser project that Google maintains. It is the foundation that most modern browsers are built on. Google takes Chromium, adds its own features and services, and ships it as Chrome. Other companies do the same: Microsoft takes Chromium and builds Edge, Brave Software takes it and builds Brave, and so on.
This matters because the engine itself is largely neutral on privacy. It is what the browser maker adds on top, and what they choose to remove or change, that determines how much of your browsing behaviour gets tracked, shared, or sold.
The main Chromium browsers and their privacy stance
Google Chrome
Chrome is the most used browser in the world and the worst of the major options for privacy. Google's business model is built on advertising, and Chrome serves that model directly. It does not block third-party tracking cookies by default. In 2025, Google reversed its earlier plan to phase them out, meaning cross-site tracking remains the standard across most of the web when you use Chrome.
Chrome also gives websites access to a wide range of browser APIs that allow fingerprinting: techniques that identify you across sites even without cookies, using details like your screen resolution, fonts, GPU, and audio output. Chrome does very little to limit this.
Microsoft Edge
Edge is built on Chromium and ships with Microsoft's own tracking on top. It includes a "tracking prevention" setting, but this is off or set to "balanced" by default, which still allows a significant amount of tracking through. Microsoft collects browsing data for its own advertising and personalisation systems, and Edge makes several calls home to Microsoft servers during normal use.
It is meaningfully better than Chrome on paper, but it still operates within the same advertiser-friendly assumptions. You are not the customer; you are the product.
Vivaldi
Vivaldi is a power-user browser with strong customisation features and a built-in tracker and ad blocker. It is notably better than Chrome and Edge on privacy and is run by a company that has no advertising business to protect. Vivaldi states that it does not track users and does not profile them.
The gap with Brave is fingerprinting. Vivaldi does not implement fingerprint randomisation to the same degree, meaning a determined tracker can still build a profile of you across sites even if cookies are blocked. For most users it is a solid choice, but it requires more configuration to get to the same privacy level Brave ships with out of the box.
Opera
Opera was a respected European browser for decades. In 2016 it was sold to a Chinese investment consortium. Since then it has added a built-in VPN, a crypto wallet, and an AI assistant, but independent audits have raised concerns about what data it collects and where it goes. Most privacy researchers would not recommend it for users who take privacy seriously.
Why Brave is the best option
Brave starts from a different position to the others. It was built specifically to be private by default, rather than having privacy features bolted on later. The company makes money through an opt-in advertising model that does not involve collecting your data, which means there is no commercial incentive to track you.
Brave Shields
Every site you visit in Brave is processed through Brave Shields, which blocks third-party trackers, cross-site cookies, and fingerprinting attempts automatically. You do not need to install an extension or change a setting. It just works from the moment you open the browser.
Brave blocks around 4.2 billion trackers per day across its user base. For comparison, uBlock Origin (the most popular ad-blocking extension for Chrome) has to be installed separately, and Chrome is gradually restricting the extension APIs it relies on through the Manifest V3 changes, which will make it less effective over time.
Fingerprint randomisation
This is one of the most meaningful technical differences between Brave and its competitors. Fingerprinting is a tracking technique that does not use cookies at all. Instead, it reads details about your browser and device — your screen size, fonts, GPU, audio stack, canvas rendering — and combines them into a profile that identifies you.
Brave randomises these values on a per-site, per-session basis. That means the fingerprint a site sees for you looks slightly different every time, making cross-site tracking via fingerprinting effectively useless. Chrome does almost nothing to address this. Edge and Vivaldi do a limited amount. Brave takes it seriously.
Removal of Google infrastructure
When you use Chrome or any browser built on standard Chromium, the browser makes regular calls to Google servers: for Safe Browsing, for update checks, for usage statistics. Brave strips these out and replaces them with its own privacy-respecting alternatives, or removes them entirely. Safe Browsing in Brave runs locally rather than sending your visited URLs to Google.
Tor integration
Brave includes a built-in Private Window with Tor. This routes your traffic through the Tor network, masking your IP address from the sites you visit and from your internet provider. It is not as complete as using the full Tor Browser, but it is the only mainstream Chromium browser that offers Tor integration at all, and it is useful for occasional lookups where you want your IP address kept out of it.
No data collection
Brave does not collect browsing history, search queries, or usage data unless you explicitly opt in to their Brave Rewards programme. That programme is entirely optional and involves viewing ads in exchange for a small amount of cryptocurrency. If you ignore it, it never activates. The browser simply runs without sending anything home.
How the browsers compare
Common questions about switching to Brave
Will my extensions still work?
Yes. Brave supports the Chrome Web Store, so any extension you currently use in Chrome will work in Brave without any changes. The main exception is that Brave's built-in blocking makes many ad-blocker extensions redundant since Brave already handles that job natively and more effectively.
Will websites break?
Occasionally. A small number of sites rely on the same trackers that Brave blocks, and you might find a login or a video player doesn't load as expected. In those cases you can lower Brave's Shields for that specific site without changing your settings globally. It is a rare problem and the fix takes about two seconds.
Is it really faster?
Yes, noticeably. Because Brave blocks trackers and ads before they load, pages render faster and use less bandwidth. Independent tests in 2026 show Brave using around 44% less RAM than Chrome under equivalent loads. If you're on a laptop, the battery difference is meaningful too.
What about Firefox?
Firefox is not Chromium-based. It runs on Mozilla's Gecko engine and is worth considering if you want to move away from the Chromium ecosystem entirely. For privacy it is comparable to Brave with some configuration, though Brave's defaults are stronger out of the box. Firefox's main advantage is that it does not contribute to Google's near-monopoly on browser engine development.
A note on what the browser can and cannot protect
Switching to Brave makes a real difference to how much data third parties collect about you while you browse. But the browser is only one part of the picture.
When you hand over your real email address or mobile number to sign up for something, that information lives in that company's systems regardless of which browser you used to type it in. A more private browser does not undo that exposure. That is where tools like email aliases and virtual numbers come in: they mean the contact details you give out are never your real ones in the first place.
Browser privacy plus contact privacy: Brave stops sites from tracking your browsing. Privify stops sites from having your real email and phone number. Together they cover two different but equally important parts of staying private online.
The short version
If you use Chrome, you are giving Google's advertising business a front-row seat to everything you do online. Edge is better but still built around Microsoft's commercial interests. Vivaldi is a good browser that requires more effort to get to a strong privacy baseline. Brave is the one that ships with the right defaults, blocks the most tracking, and does not have a financial reason to compromise on any of it.
It takes about two minutes to download and import your bookmarks. For most Chrome users it is the single highest-impact privacy change they can make today.
