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
CriticalGecko base that avoids the Chromium monoculture. Firefox privacy defaults and auditable open-source builds are the point as much as the engine.
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
HighWorkspaces, vertical tabs, Compact Mode, Glance and Split View. Minimal spatial model that feels close to Arc with little chrome.
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
HighBrowser only. No built-in mail, calendar or feeds. You use web apps and extensions, which keeps the app lighter.
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
HighZen Mods, Compact Mode and community tweaks let you reshape chrome quickly. Closer to theming than digging through settings.
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
HighFirefox Add-ons. Most popular extensions have Firefox ports. For the few Chrome only tools you will need a Chromium fallback.
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
MediumGecko runs well on Apple Silicon. Workspaces and Compact Mode help keep focus. Some heavy web apps are a bit less tuned than on Chromium.
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
MediumNo built-in AI browser. AI use comes from web tools and extensions, which fits the privacy and minimal stance.
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
MediumFree and open-source, donation funded, no paywall. Firefox privacy defaults and auditable builds.
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
Workspaces, vertical tabs, Compact Mode and Glance are the closest Arc recreation staying off Chromium and keeping mail clients separate.
2Power user who wants one app for browsing, mail and feeds
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 command chains, gesture mapping and panel controls go furthest. Zen is faster but less exhaustive.
4Open-source purist on Apple Silicon
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
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
In Vivaldi export bookmarks, passwords, notes and feeds. Install Zen with brew install --cask zen-browser, recreate Workspaces, enable Compact Mode, search Firefox Add-ons for extension equivalents, add Zen Mods for chrome tweaks and set up Firefox Sync. Keep Vivaldi as the Chromium fallback. Mail does not migrate automatically.
