Where should I download Zigzag from?

Only from zigzagbrowser.com or the developer’s Homebrew tap (zigaowang/tap/zigzag). Those are the only official sources; both serve the same signed, notarized build. Avoid third-party download mirrors.

What are the system requirements for Zigzag?

macOS 15.4 or later on Apple silicon or Intel. The minimum exists because Chrome-extension support uses Apple's WKWebExtensionController. There is no Windows, Linux, iOS or Android version, and none is planned.

Can I install Zigzag with Homebrew?

Yes: brew install --cask zigaowang/tap/zigzag. The cask lives in the developer’s own tap and updates through brew upgrade like any other cask.

Does Zigzag import my Arc data?

Yes — it is a flagship feature. On first launch, or later via File → Import from Another Browser → Arc, your Spaces, pinned tabs, Favorites, history and passwords move over in one pass. Open tabs are intentionally left behind.

How big is the Zigzag download?

About 18 MB, because the browser uses the WebKit engine already built into macOS. Compare that with Arc at 871 MB or Chrome at 1,463 MB on the same machine.

Does Zigzag auto-update?

Yes. Updates come through an EdDSA-signed feed and install automatically in the background. Homebrew installs can instead run brew upgrade --cask zigzag.

Is Zigzag safe to install?

Structurally, yes: the build is Developer ID-signed and notarized, there is no account or telemetry, external connections are publicly listed, and the Apache 2.0 code is open to inspection.

Zigzag Browser Download: Free, 18 MB, Ready in a Minute

Zigzag is the open-source Mac browser built in the weeks after Arc announced its shutdown. No account, no telemetry, no installer bloat — a signed 18 MB app you can grab from the official site or install with Homebrew. This page walks through both ways, the system requirements, and what happens on first launch.

Two ways to install

How to download Zigzag Browser

There are two legitimate ways to get Zigzag: the signed DMG from the official site, or Homebrew for terminal-first users. Both are free and land on the same app.

Option 1 · Official DMG

Download the DMG from zigzagbrowser.com

The site links straight to the signed, notarized disk image. The same page lists every external connection the app can make — a rarity among browsers.

1
Open zigzagbrowser.com and press the download button — the site serves the build for your Mac directly.
2
Open the downloaded DMG and drag Zigzag into Applications.
3
Launch Zigzag. On first run it offers a one-click import of your Arc data.

Option 2 · Homebrew

Install with Homebrew

Zigzag ships a first-party Homebrew cask. Updates then arrive through brew upgrade like everything else on your Mac.

terminal

$ brew install --cask zigaowang/tap/zigzag

The cask lives in the developer's own tap — verify the publisher before installing anything via brew.

Before you install

Zigzag Browser system requirements

Zigzag is macOS-only by architecture — it builds on the system WebKit engine, which is also why the minimum version exists.

Operating system: macOS 15.4 or later
Chip: Apple silicon or Intel (universal build)
Download size: 18 MB
Account: None required
License: Apache 2.0 open source
Windows / Linux / mobile: Not available — and not planned

The macOS 15.4 floor exists because Chrome-extension support relies on Apple's WKWebExtensionController.

First launch

Import your Arc data during first run

If you are arriving from Arc, setup takes about a minute. Zigzag asks on first launch whether to import, and keeps the structure you spent years building.

The whole app is smaller than most browsers' installer helpers — 18 MB next to Arc's 871 MB.

One-click Arc import

Choose File → Import from Another Browser → Arc and Spaces, pinned tabs, Favorites, history and passwords come across in one pass.

Your Spaces survive

Color-coded Spaces and pinned structure are preserved; open-tab piles are deliberately left behind for a clean start.

Passwords via Keychain

Imported credentials land in the macOS keychain, so Touch ID and iCloud sync keep working.

After install

Updates and uninstalling

Zigzag updates itself quietly. There is nothing to configure and no updater account.

Automatic signed updates

Releases arrive through an EdDSA-signed update feed and install themselves. You can also watch releases on the project’s open repository.

Updating via Homebrew

If you installed through brew, run brew upgrade --cask zigzag to stay current.

Clean uninstall

Zigzag stores data in Application Support and preferences in the standard macOS locations. Delete the app and those folders and nothing remains — no background daemons, no login items.

On Windows?

Zigzag does not run on Windows — Tabbit does

Zigzag's macOS-only design is permanent, not a roadmap item: the browser is built on Apple's WebKit. If your main machine runs Windows 10 or 11 and you still want a fast, private browser with AI built in, that is exactly what Tabbit ships today.

Tabbit is free during the public beta, native on Windows and macOS, and routes your questions across Claude, GPT, Gemini, DeepSeek and Kimi with agent automation you approve step by step.

✓Native Windows 10/11 and macOS builds — same AI features on both
✓Sidebar AI summaries, multi-model answers and deep-research reports
✓Agent Mode fills forms, moves data and runs multi-step tasks with visible approval
✓Free during the public beta — no credit card, no waitlist

Safety check

Is downloading Zigzag safe?

As browser downloads go, Zigzag checks nearly every box — mostly because of what it does not have.

Signed and notarized

The DMG is signed with a Developer ID and notarized by Apple, so Gatekeeper verifies it on first launch.

No account, no telemetry

There is no signup step and no analytics. The site publishes the full list of external connections — essentially just the signed update feed.

Open source (Apache 2.0)

Anyone can audit the code, and anyone can fork it if the original developer ever steps away.

Engine security from Apple

Because Zigzag uses the system WebKit engine, security patches arrive with macOS updates — no waiting on the developer to rebase Chromium.

Quick answers

Zigzag Browser download FAQ

Yes. Zigzag is free to download and use, and the source code is published under the Apache 2.0 license. The name and icon are the developer’s trademarks, but the code can be used, modified and forked by anyone, including commercially.

Need a browser that also does the work?

Tabbit pairs full Chromium compatibility with Claude, GPT, Gemini, DeepSeek and Kimi — summaries, deep research and agent automation, free in your browser.
