Our verdict

How we compare apps

Vivaldi takes a narrow win as the more complete power suite for Mac users who want one Chromium browser that replaces several apps. Workspaces, tiling, Mail, Calendar, Feeds, auto-hide UI and Chrome Web Store support were refined steadily through the Vivaldi 7 line on Tahoe 26. Zen is the more open and lighter Arc style choice, with Workspaces, Compact Mode and Mods and no cost. For Arc refugees and Firefox extension users Zen remains the better daily driver.

Read the quick answer

Which is better: Zen Browser or Vivaldi?

TL;DR

Zen Browser vs Vivaldi: Vivaldi takes a narrow win as the more complete power suite for Mac users who want one Chromium browser that replaces several apps.

In-Depth Overview

What is Zen Browser?

Zen Browser is a free and open-source browser on Firefox Gecko that brings Arc style spatial browsing to a privacy respecting, non-Chromium base. The core idea is Workspaces that group tab clusters, a vertical sidebar, Compact Mode that hides browser chrome when you need focus, Glance previews and Split View, plus Zen Mods. Mods are community themes and small tweaks that reshape chrome without adding extensions. During 2026 Zen followed Firefox closely, with builds on the 153 and 153.0.1 line and quick CVE patches, including a 44 CVE security rollup in 1.21.9b and workspace polish in 1.21.10b in early August 2026. Releases are public on GitHub with frequent beta and stable notes. On Mac it is native on Apple Silicon and Intel, notarised for Tahoe 26, and it inherits Firefox privacy defaults, container tabs and the Add-ons catalogue. There is no paid tier, it is donation funded. For Mac users who liked Arc calm but want something open and still shipping, Zen is the closest living Arc replacement that stays off Chromium, and it helps if you already live in the Firefox extension world.

What is Vivaldi?

Vivaldi is a free Chromium browser for people who want to shape the browser instead of adapting to it. It was started by Opera co-founders and pairs Chromium compatibility with a large built-in toolset. Expect stacked tabs with two level stacks, tab tiling, Workspaces, vertical or horizontal tabs, a reading list, notes, annotated screenshots, built-in mail, calendar, feeds and contacts, strong ad and tracker blocking, mouse gestures, command chains, keyboard mapping and deep control over every panel and toolbar. Releases in the Vivaldi 7 generation kept coming through early 2026. Version 7.9 in March 2026 added auto-hide UI that trims chrome for focus, one more iteration on interface flexibility. On macOS Vivaldi ships native Apple Silicon and Intel builds, is notarised for Tahoe 26, supports the Chrome Web Store and syncs across desktop and mobile without needing a Google account. There is no paid browser tier. Revenue comes from search deals and optional services. For Mac users who want a single Chromium browser that replaces separate mail, calendar and feed apps while keeping Chrome extension support and exhaustive settings, Vivaldi is the most complete power-user suite without leaving Chromium.

Detailed Feature Comparison

Engine & monoculture stance

Critical importance

Zen Browser

Excellent

Gecko base that avoids the Chromium monoculture. Firefox privacy defaults and auditable open-source builds are the point as much as the engine.

Vivaldi

Good

Chromium with Vivaldi privacy tuning and built-in blocking. Best site compatibility, but it still adds to Chromium share. Vivaldi is open about that trade.

Verdict: Choose Zen if avoiding Chromium matters to you. Choose Vivaldi if you need Chromium site fidelity and Chrome extensions.

Tab & workspace organisation

High importance

Zen Browser

Excellent

Workspaces, vertical tabs, Compact Mode, Glance and Split View. Minimal spatial model that feels close to Arc with little chrome.

Vivaldi

Excellent

Workspaces, tab stacks with two level stacks, tiling, vertical tabs and a lot of configuration. More maximal and adjustable than Zen.

Verdict: Both handle workspaces well. Zen feels lighter. Vivaldi feels more adjustable.

Built-in productivity suite

High importance

Zen Browser

Fair

Browser only. No built-in mail, calendar or feeds. You use web apps and extensions, which keeps the app lighter.

Vivaldi

Excellent

Mail, Calendar, Feeds, Contacts, Notes, screenshots and translator live inside the browser. One app replaces several clients if you want fewer apps open.

Verdict: Vivaldi is the suite. Zen stays browser only by design.

Customisation

High importance

Zen Browser

Excellent

Zen Mods, Compact Mode and community tweaks let you reshape chrome quickly. Closer to theming than digging through settings.

Vivaldi

Excellent

Settings for every toolbar, panel, gesture, command chain and search. If you like tuning the browser itself, nothing else offers this much surface.

Verdict: Zen is quicker minimal custom work. Vivaldi goes deeper for tinkerers.

Extensions & compatibility

High importance

Zen Browser

Good

Firefox Add-ons. Most popular extensions have Firefox ports. For the few Chrome only tools you will need a Chromium fallback.

Vivaldi

Excellent

Full Chrome Web Store support on Chromium. Broadest extension coverage and reliable enterprise site rendering.

Verdict: Vivaldi for Chrome extension dependent work and web app testing.

Performance & battery on Mac

Medium importance

Zen Browser

Good

Gecko runs well on Apple Silicon. Workspaces and Compact Mode help keep focus. Some heavy web apps are a bit less tuned than on Chromium.

Vivaldi

Good

Chromium with Vivaldi optimisations and auto-hide UI in 7.9 to trim chrome cost. Usual Chromium multi-process overhead still applies.

Verdict: Both run well on Tahoe 26 and Apple Silicon. Vivaldi 7.9 auto-hide and Zen compact mode reach similar focus in different ways.

AI assistance

Medium importance

Zen Browser

Fair

No built-in AI browser. AI use comes from web tools and extensions, which fits the privacy and minimal stance.

Vivaldi

Good

No dedicated assistant like Brave Leo or Edge Copilot. Vivaldi puts the focus on its productivity suite and controls. AI work happens on the web when you need it.

Verdict: Neither leads on built-in AI. Decide on engine, suite and feel instead.

Privacy, price & openness

Medium importance

Zen Browser

Excellent

Free and open-source, donation funded, no paywall. Firefox privacy defaults and auditable builds.

Vivaldi

Good

Free with no browser paywall, strong blocking and independent ownership by former Opera founders. Source model is closed core with open contributions, funded through search deals.

Verdict: Zen for purest openness and donation model. Vivaldi is free and independent without being donor funded.

Who Should Choose Which?

1Arc refugee who wants Arc-like calm without Chromium

Zen Browser

Workspaces, vertical tabs, Compact Mode and Glance are the closest Arc recreation staying off Chromium and keeping mail clients separate.

Vivaldi

Built-in Mail, Calendar, Feeds, Notes and tiling plus Chrome extension support keeps one Chromium suite for most work.

3Tinkerer who enjoys shaping every toolbar and gesture

Vivaldi

4Open-source purist on Apple Silicon

Zen Browser

Fully open source and auditable, donor funded with Firefox privacy defaults. Cleanest non Chromium daily driver on Tahoe 26.

5Developer testing Chrome-specific web apps

Vivaldi

Chromium fidelity with Chrome Web Store coverage for production-like testing in a highly adjustable daily browser.

Migration Guide

Zen Browser → Vivaldi

In Zen export bookmarks and passwords and note which Workspaces and Mods you rely on. Install Vivaldi with brew install --cask vivaldi or the Vivaldi installer, set up sync, mirror Workspaces, turn on vertical tabs or two level stacks, add mail and feed accounts if you want them inside the browser, install Chrome Web Store extensions and map gestures and command chains. Keep Zen for a week to catch Firefox only add-on gaps.

Vivaldi → Zen Browser

Frequently Asked Questions

Is Zen Browser or Vivaldi more private?
Zen inherits Firefox privacy posture with open source builds and donor funded governance and no Chromium data surface. Vivaldi adds strong blocking and skips Google account requirements but still runs on Chromium. For pure non Chromium privacy Zen is stronger. For private browsing that stays on Chromium, Vivaldi is solid without extra extensions.
Can I use Chrome extensions in Zen Browser?
No. Zen uses Firefox Add-ons. Most popular extensions have Firefox versions but Chrome only extensions need a Chromium browser such as Vivaldi or Brave. That is one reason many power users keep both engines installed.
Does Vivaldi's built-in Mail and Calendar replace Apple Mail?
For many people yes. Vivaldi Mail handles IMAP, Calendar handles CalDAV and Feeds handles RSS inside the browser, so you consolidate clients. If you live in Apple Mail, Calendar or Gmail web views, Vivaldi can still cut app switching while Zen users keep their existing mail app.
Which browser feels more like Arc?
Zen. Workspaces, vertical tabs, Compact Mode and Glance were built to bring Arc style calm to a Firefox base. Vivaldi is more maximal and adjustable, with deeper tiling and stacking but busier chrome until you turn on auto-hide.
Are both browsers free?
Yes. Both are free on macOS Tahoe 26 with no premium browser tier. Zen runs on donations as open source. Vivaldi is funded through search deals and optional services. Neither puts Workspaces, vertical tabs or customisation behind payment.
Do both support macOS Tahoe 26 and Apple Silicon?
Yes. Both ship native Apple Silicon and Intel builds notarised for Tahoe 26. Zen installs as zen-browser and Vivaldi as vivaldi through Homebrew or from the official disk images. Both ship regular security fixes.
Which browser is better for heavy customisation?
Vivaldi if you enjoy controls for every panel, toolbar, gesture and command chain. Zen is good for quicker community Mods and Compact Mode but covers less total surface than Vivaldi settings.
Is there any AI assistant in either browser?
Neither ships a dedicated assistant in the style of Brave Leo or Edge Copilot. Both keep the focus on browsing and on Vivaldi side the productivity suite. AI work goes through web tools or extensions when you need it.
Should I install both?
Many power users do. Use Zen as the light, open source, non Chromium daily browser and keep Vivaldi as the Chromium suite for Chrome specific sites, built-in Mail and Calendar and extension coverage. Together they cover both Firefox and Chromium on Mac.
How do I migrate between Zen and Vivaldi?
Export bookmarks, passwords, notes and for Vivaldi feeds. Install the other browser, rebuild Workspaces and vertical tabs, move extensions to the other store and reset gestures or Mods. Mail does not move automatically, you re-add IMAP accounts in Vivaldi if you use its suite.
