Best Vivaldi Alternatives

Floorp is a passion project from Japan that answers the question: "What if Firefox was as customizable as Vivaldi?" Built on the Firefox ESR (Extended Support Release) base, it retains the privacy and engine of Mozilla but unlocks the interface, allowing for vertical tabs, multi-row tab bars, and flexible sidebar panels.

It is community-driven and open-source, ensuring transparency. Users love it for features like "Workspaces" (grouping tabs) and its ability to completely restyle the browser chrome. It fully supports the Firefox extension ecosystem, so you don't lose your favorite add-ons.

Because it is a smaller project, it may not receive day-one security patches as instantly as mainline Firefox, though the team is very active. For users who love the Gecko engine but feel constrained by Firefox's default interface, Floorp is the perfect middle ground.

Zen Browser takes the reliable, privacy-friendly engine of Firefox and wraps it in a beautiful, modern interface inspired by Arc. It brings features like vertical tabs, split views, and workspaces to the Gecko ecosystem, proving that you don't need Chromium to have a cutting-edge UI.

It focuses on "calmness" and ergonomics. The interface is designed to reduce visual noise and help you stay in the flow. It includes thoughtful touches like a sidebar for easy navigation and keyboard shortcuts that power users will appreciate.

As a relatively new project, it is still evolving, and you might find the occasional rough edge compared to a decade-old browser. However, for users who want the modern features of Arc but refuse to leave the privacy and independence of Firefox, Zen is the browser they have been waiting for.

Microsoft Edge has successfully reinvented itself as a top-tier browser. Built on the same Chromium engine as Chrome, it matches Google's speed and compatibility but adds Microsoft's own productivity flavor. Features like Vertical Tabs, Workspaces, and Split Screen make it surprisingly powerful for work.

It is heavily integrated with the Microsoft ecosystem, with Copilot (Microsoft's AI) built into a side pane and sign-in tied to your Microsoft account, Microsoft 365, and OneDrive. "Sleeping Tabs" is a standout feature that aggressively freezes unused tabs to save RAM, often making Edge feel lighter than Chrome on aging hardware.

Some users find the aggressive promotion of Microsoft services intrusive. However, as a default Windows browser, it is no longer just a tool to download Chrome—it is a genuinely capable, feature-packed competitor that works brilliantly in enterprise and office environments.

Brave is built on the premise that you shouldn't have to configure your browser to be private—it should just work. Out of the box, Brave Shields aggressively block third-party trackers, ads, and fingerprinting scripts. This not only protects your data but often makes pages load faster by preventing heavy ad networks from downloading.

Beyond blocking, Brave includes a suite of privacy tools: a built-in firewall + VPN (paid), a privacy-focused search engine, and even a Tor mode for private windows to route traffic anonymously. It allows you to opt-in to privacy-respecting ads in exchange for cryptocurrency rewards, flipping the traditional ad model on its head.

The "crypto" features can feel cluttered to some, though they are easily disabled. Underneath, it runs on Chromium, so all your favorite Chrome extensions work perfectly. If you want the speed and compatibility of Chrome without the Google tracking, Brave is an excellent drop-in replacement.

Mozilla Firefox stands as the last major independent browser, powered by its own Gecko engine rather than Chromium. This independence allows it to prioritize user agency over corporate interests, offering a browsing experience that is open-source, transparent, and highly customizable.

Privacy is woven into the core. Features like Enhanced Tracking Protection block invasive trackers by default, while built-in container tabs (on by default since Firefox 153) let you isolate your digital lives—keeping Facebook data away from your banking, for example. Its customization engine is unmatched, allowing you to completely overhaul the UI with CSS if you choose.

While it may occasionally trail Chrome in raw JavaScript benchmarks, the difference is rarely noticeable in daily use. The extension library is mature and robust. For users who value the health of the open web and want a browser that serves them rather than advertisers, Firefox is the definitive choice.

Opera believes in the "batteries included" philosophy. Instead of asking you to hunt for extensions, it bakes popular tools directly into the interface. A free (proxy) VPN, an ad blocker, and a snapshot tool are available immediately upon installation.

The Sidebar is its defining feature, giving you persistent access to WhatsApp, Messenger, music players like Spotify, and "Aria," Opera's native AI assistant. This setup is perfect for users who want to keep chat and media visible without juggling separate windows or tabs.

The interface can feel busy compared to minimalist alternatives, and some users may prefer open-source privacy standards over Opera's proprietary stack. However, for users who want a feature-rich, "Swiss Army knife" browser that is ready to go from the first launch, Opera is a top contender.

Orion is built by Kagi, the company behind the paid search engine, and takes a unique approach: a fully native WebKit browser for macOS and iOS that can run extensions from the Safari, Chrome, and Firefox extension stores. Written in Swift and Objective-C with native Apple APIs, it delivers Safari-class speed and energy efficiency while opening up over 150,000 extensions from competing ecosystems.

Privacy is a core principle. Orion collects zero telemetry—no usage data, no analytics, no identifiers. Built-in ad and tracker blocking is enabled by default, and the browser markets itself as "AI-proof," deliberately avoiding embedded AI agents to prevent AI-driven data collection. It includes vertical tree-style tabs, a built-in password manager, iCloud sync for tabs and bookmarks, reader mode, and AppleScript automation support.

Extension compatibility covers roughly 70% of the WebExtensions API, meaning most popular Chrome and Firefox extensions work but some complex ones may have issues. Kagi had been building Linux and Windows versions, but in October 2026 it ended that work to concentrate on Apple platforms, and said it will open-source the code for the community to continue. For Mac and iPhone users who want Safari's performance without its limited extension ecosystem, Orion fills a niche no other browser occupies.
