Brave and Mullvad Browser both score 5 for privacy in our ratings, and that is about the only rating they share. Brave is a full everyday browser that blocks a lot by default. Mullvad Browser is a hardened tool built to make you look like every other user, and it gives up most conveniences to do it. The real question is whether you need that much protection, not which of them protects you better.
Two ways to beat fingerprinting
Fingerprinting is the main technical difference. Brave defends against it by randomising: it adds small amounts of noise to what sites can measure, such as canvas and audio output, so your fingerprint changes from site to site and session to session. Mullvad Browser uses the Tor Project's approach, uniformity. It runs Tor Browser's anti-fingerprinting patches on Firefox ESR, normalises window sizes through letterboxing, standardises fonts and timezones, and blocks canvas and WebGL readouts, so every Mullvad Browser user looks identical. Privacy researchers generally rate uniformity as stronger against determined trackers. It only works if you do not customise anything, though.
Mullvad Browser runs in permanent private mode, with no history and no cookies kept between sessions. It ships with uBlock Origin and NoScript, has its telemetry removed at compile time, and sends DNS through Mullvad's encrypted DNS. It does not hide your IP address. You are expected to pair it with a VPN, Mullvad's (a flat €5 a month) or anyone else's.
Brave blocks ads, trackers and fingerprinting scripts by default, dismisses cookie banners and strips targeted ads from YouTube. For IP privacy it offers a paid VPN and private windows routed through Tor.
What the hardening costs
Mullvad Browser scores 2 for ease of use, among the lowest in our directory, against Brave's 3. It has no sync and no password manager, and bookmarks are not its strength. It scores 2 for extensions because it actively discourages adding any: each one makes you stand out. Strict settings break some sites, and it is desktop only (Mac, Windows and Linux).
Brave is everything Mullvad Browser chooses not to be. It scores 5 for extensions with the full Chrome Web Store, 4 for customizability against Mullvad's 2, and 4 for speed against 3. It syncs across all five major platforms, keeps your logins, and scores 4 for AI features through its Leo assistant, where Mullvad scores 1.
Source code is the last difference. Mullvad Browser is fully open source; Brave's source is only partly open, and it carries the optional, off-by-default Brave Rewards crypto system.
Which should you choose?
Choose Brave if you want strong privacy in a browser you can actually live in: synced across your phone and computer, compatible with every Chrome extension, with Tor windows for the occasional sensitive search.
Choose Mullvad Browser if you already use a VPN you trust and want to be unremarkable to trackers during specific sessions: research you would rather not be linked to you, or browsing on a shared network. Many people run both, with Brave as the daily browser and Mullvad for the sessions that matter.
