Arc is a Mac-native web browser built by The Browser Company that reimagines how your tabs, windows, and web tools coexist — replacing the traditional browser chrome with a collapsible sidebar, Spaces for context-switching, and a command bar that keeps your hands on the keyboard.
What is Arc?
Arc is a Chromium-based browser for macOS that fundamentally rethinks the browser's interface, replacing the classic tab strip with a persistent sidebar that organises your browsing into named Spaces, Folders, and pinned tabs — all while remaining fully compatible with every Chrome extension you already rely on.
Underneath that opinionated shell, Arc runs the same rendering engine as Chrome and Edge, which means site compatibility is essentially a non-issue. What changes is everything around the web page: where your tabs live, how you name and colour-code them, and how quickly you can navigate without touching the mouse.
What does Arc do best?
Arc's standout strength is ruthless organisation. The Spaces feature lets you maintain genuinely separate contexts — say, one for client work, one for personal research, one for the current side project — each with its own pinned tabs, colour scheme, and open windows that never bleed into each other.
I've used Arc as my daily driver for months and the thing I keep coming back to is Little Arc: a lightweight floating window (⌘N from the Dock or a URL-click from another app) that opens a URL without disturbing whatever Space you were in. It sounds minor until you've been interrupted by a link fifty times in a workday and you realise you've never accidentally buried your working context.
- Spaces — named, coloured browser contexts that don't pollute each other
- Command Bar — ⌘T to search history, tabs, bookmarks, and run Arc actions in one keystroke
- Boosts — per-site CSS/JS overrides that let you skin or simplify any webpage
- Little Arc — ephemeral floating window for one-off URLs
- Split View — native side-by-side tabs without any extension
- Picture-in-Picture media — videos float automatically when you switch tabs
Chrome extension compatibility is near-perfect — 1Password, uBlock Origin, and Vimium all run without a hitch.
Is Arc free?
Arc is free to download and use with no feature tiers or paywalls — The Browser Company's stated model is to build premium products separately rather than gate the core browser. You sign in with an account, which enables sync across Macs, but no subscription is required for any of the features described here.
Who should use Arc?
Arc suits Mac power-users who live in the browser and have given up fighting tab overload. If you routinely maintain thirty-plus tabs across two or three distinct work contexts, Arc's Spaces model will feel like a revelation compared with Chrome's flat tab strip or even Safari's Tab Groups.
Developers and designers particularly benefit from Boosts and the built-in devtools (a straight Chromium DevTools panel, identical to Chrome's). Keyboard-first workers who have already adopted Raycast or Alfred will feel immediately at home with the Command Bar. Arc is a harder sell for anyone who prefers Safari's energy efficiency and tighter iCloud Keychain integration, or for users who share a browser with family members and find Arc's account-centric design a friction point.
What are the best Arc alternatives?
Safari remains the benchmark for battery life and Continuity features on Apple Silicon — if your MacBook's hours-per-charge matters more than tab organisation, Safari wins. Chrome is the obvious fallback when Arc's opinionated layout feels like too much change. Firefox is the privacy-first alternative, especially with uBlock Origin running pre-Manifest V3 rules. Orion by Kagi is worth mentioning for users who want Chromium-plus-WebKit extension support without a sign-in requirement. Brave targets the ad-blocking crowd with built-in shields. None of these rethink the browser's structural UI the way Arc does.
How does Arc compare to Chrome?
Arc and Chrome share the same rendering core and extension ecosystem, so web compatibility and DevTools parity are essentially equal. The differences are entirely interface-level: Chrome gives you a horizontal tab strip and a minimal address bar; Arc gives you a vertical sidebar, Spaces, the Command Bar, and Boosts. Chrome is significantly lighter on RAM per tab in extended sessions — Arc's sidebar architecture and sync features do add overhead. For a user who wants the fewest surprises, Chrome wins; for a user who wants a smarter workspace, Arc wins.
