Zen Browser

Zen Browser has quietly become one of the most-recommended browsers on r/browsers in 2026, and the pitch is easy to understand: Firefox as a base, plus Arc-style workspaces, split view, and glance link previews on top. For anyone who loved Arc but bounced when The Browser Company stopped active development in mid-2025, Zen is the natural next step. Still, Zen is a small project on Firefox time, and not every user wants a Chromium alternative to also be a Firefox alternative. If you’re weighing the trade-offs, here are seven desktop Zen Browser alternatives that cover privacy, power-user features, and every combination in between.

Why Zen Browser sticks

Firefox is the honest starting point. Zen is a Firefox fork, which means the entire Mozilla plugin ecosystem is available on day one. Users switching from Firefox lose almost nothing except muscle memory around chrome UI.

Workspaces are the Arc idea done right. Split by project, colour-code, and each workspace holds its own tab list. If you had four tabs about work always fighting for attention with six tabs about a side project, Zen lets you close one context entirely and reopen it later without state loss.

Compact Mode is unusually good. Every browser claims minimal chrome; Zen actually delivers it, with a floating URL bar and vertical tab hover that comes and goes with the pointer. It’s the kind of feature you don’t miss until you go back to a browser without it.

The alternatives

Vivaldi

Vivaldi is the closest desktop match to Zen’s power-user pitch, built on Chromium instead of Firefox. Tab stacks, split-screen tiling, a built-in mail client, calendar, feed reader, and workspaces. If you had a wish list before Zen existed, Vivaldi shipped most of it half a decade ago.

Where it falls short: The UI is dense and takes a week to configure. Sync is fine but not on par with Chrome’s or Firefox’s.

Pricing: Free.

Platforms: Windows, macOS, Linux.

Download: Vivaldi.com

Bottom line: Pick this if you want Zen-style customization on a Chromium base, plus a built-in Mail and Calendar you can actually use.

Brave

Brave is the privacy-first Chromium fork. Ads and trackers blocked by default, a private Tor tab, IPFS support, and a rewards system you can ignore. It runs any Chrome extension and doesn’t require configuration to be genuinely private.

Where it falls short: The rewards and crypto features feel out of place for anyone who just wants a browser. The default new-tab page is busy.

Pricing: Free.

Platforms: Windows, macOS, Linux.

Download: Brave.com

Bottom line: Best pick if you want Zen’s minimal-friction privacy without a Firefox base or a small dev team.

Firefox

Firefox itself is worth reconsidering. Multi-account containers, Total Cookie Protection, and the extension ecosystem Zen inherits are all in the mainline browser. Mozilla ships slowly but reliably.

Where it falls short: Chrome dominance means some sites still test poorly against Firefox. UI has fewer power-user features than Zen or Vivaldi out of the box.

Pricing: Free.

Platforms: Windows, macOS, Linux.

Download: Mozilla.org/firefox

Bottom line: For the users who want Zen’s Firefox base without a smaller project’s release cadence.

LibreWolf

LibreWolf is Firefox tuned for privacy from the first launch. Telemetry stripped, uBlock Origin bundled, and defaults hardened without you needing to touch about:config. If your interest in Zen was privacy rather than aesthetics, LibreWolf is closer to the target.

Where it falls short: Some sites break out of the box because of the hardened defaults; you’ll need to whitelist a few. Sync uses a self-hosted Firefox Sync or third-party alternatives.

Pricing: Free.

Platforms: Windows, macOS, Linux.

Download: LibreWolf.net

Bottom line: Pick this if you want the Firefox base with privacy dialled up and no aesthetics conversation.

Arc

Arc is technically in maintenance mode after The Browser Company shifted focus to Dia in 2025, but the browser still ships bug fixes and remains usable on macOS and Windows. Workspaces, sidebar tabs, and Boosts inspired most of Zen’s ideas.

Where it falls short: No active feature development. Windows version has always lagged the Mac build, and that gap is now permanent.

Pricing: Free.

Platforms: Windows, macOS.

Download: Arc.net

Bottom line: For the users who tried Arc first and want to keep using it while Zen matures. Skip if long-term support is a requirement.

Waterfox

Waterfox is another Firefox fork with a long history and a specific niche: keeping the older Firefox extensions alive alongside modern WebExtensions. If you have plugins from the pre-Quantum era that never got ported, Waterfox is the one that still runs them.

Where it falls short: Slower release cadence than upstream Firefox. UI feels dated compared to Zen or Vivaldi.

Pricing: Free.

Platforms: Windows, macOS, Linux.

Download: Waterfox.net

Bottom line: For the legacy-extension holdouts who otherwise would have to run an ancient Firefox build.

Wavebox

Wavebox approaches the problem differently. Instead of tabs, you get containers for each work app (Gmail, Slack, Notion, ClickUp) with SSO handled cleanly across identities. It’s built for people whose browser is really a wrapper around a set of work tools.

Where it falls short: The free tier is limited; the real value is behind the paid plan. Not a general-purpose browsing experience.

Pricing: Free tier; Pro starts around $10/month.

Platforms: Windows, macOS, Linux.

Download: Wavebox.io

Bottom line: Pick this if your browser is mostly a work-tools hub and you’d trade browsing for app-window discipline.

How to choose

Pick Vivaldi if you want Zen-style customization on a Chromium base with a mature Mail and Calendar. Pick Brave for a low-friction private Chromium browser. Pick Firefox if you want Zen’s foundation without the smaller team. Pick LibreWolf for Firefox hardened for privacy. Pick Arc if you’re already invested and don’t need future features. Pick Waterfox if legacy extensions matter. Pick Wavebox if your browser is really a work-app dock. Stay on Zen if the mix of Firefox foundation, workspaces, split view, and glance previews is exactly what you want, because none of these do all four at once.

FAQ

Is Zen Browser safe to use?

Zen is open source and published under the MIT license with an active community. It inherits Firefox’s security model, which is the strongest of any browser base. There are no known privacy concerns with the default configuration.

Zen Browser vs Firefox: what’s the difference?

Zen is a Firefox fork that adds Arc-style workspaces, split view, glance link previews, compact mode, and a modern UI shell. The underlying rendering engine is identical. Anything Firefox does, Zen does; the reverse is not true.

Does Zen Browser support Chrome extensions?

No. Zen is Firefox-based, so it uses Firefox WebExtensions, not Chrome extensions. Most popular Chrome extensions have a Firefox equivalent listed on addons.mozilla.org.

Is Arc dead?

Not quite. The Browser Company said in mid-2025 that active feature development had stopped, but the browser still ships security fixes and remains free to use. New features and long-term support come from the company’s Dia browser project instead.

What is the most private browser on this list?

LibreWolf ships with the hardest defaults, followed by Brave (with rewards disabled) and Firefox (with containers configured). All three keep more data on-device than a stock Chrome install.
