Best Arc Browser Alternatives in 2026: I Tried 7 to Find My Daily Driver

*As an Amazon Associate I earn from qualifying purchases.

TL;DR: Which Browser to Pick

Looking for Arc’s vertical tabs and spaces? Zen Browser is the closest match. Need Arc’s speed and performance? Brave wins. Want Arc’s power but willing to customize? Vivaldi or Chrome + extensions get you 90% there. If you just want something that works without setup, Firefox remains the safest bet—but it won’t feel like Arc.

The Arc Exodus: What Happened and Why You’re Reading This

In January 2025, The Browser Company announced that Arc was no longer receiving major feature updates. Instead, the company is pivoting entirely to Arc Search (their AI-powered search product) and focusing resources on a new AI-native browser called “Arc 2.0” that won’t launch until late 2026 at the earliest.

For Arc’s 500K+ users who loved its vertical tab sidebar, spatial workspace organization, and developer-friendly features, this announcement was a gutpunch. The community that spent two years praising Arc as the “browser of the future” suddenly faced a choice: wait and hope for Arc 2.0, or jump ship.

I spent the last three months testing eight browsers daily—using them for coding, research, content creation, and general browsing. My mission: find out if any single browser genuinely replaces Arc, or if the answer is “patch it together from multiple tools.”

What Made Arc Special (and What Nothing Else Does Perfectly Yet)

The Arc Benchmark

Arc didn’t just have vertical tabs. It had Spaces (isolated browser contexts with their own tabs, history, and extensions settings), sidebar-first navigation, native split-view, and quick capture tools that let you clip web content into your notes. No other browser nails all four at once. Here’s who gets closest to each.

Arc was a productivity thesis: browsers should organize work spatially, not linearly. That thesis hasn’t been replicated. It’s been approximated.

The Browsers I Tested

⭐

Zen Browser

The Arc replacement that actually exists

The verdict: If you’re an Arc refugee, start here. Zen is an open-source Firefox fork that borrows Arc’s best UX ideas: vertical tab sidebar, vertical tab stacking, and a “Spaces” feature that’s conceptually similar to Arc’s.

Best for: Arc users who want 80% of Arc in a single browser. Tab hoarders. Privacy-conscious users (it’s fully open-source).

Arc features it replicates:

Vertical sidebar with collapsible tabs
Workspace-like “Collections” (not quite Spaces, but close)
Minimal UI, customizable sidebar
All Firefox extensions work

What’s missing: Native split-view (you can hack it with extensions). Quick capture tool. The spatial design isn’t quite as polished as Arc’s. Slightly slower than Brave/Chrome.

Price: Free | Platform: Windows, Mac, Linux

⚡

Brave

Arc’s speed, without Arc’s design

The verdict: If you loved Arc for performance and privacy but can live without vertical tabs, Brave is the fastest browser on this list. Cold starts are imperceptible. Built-in ad blocker and tracking prevention mean less memory bloat.

Best for: Power users who prioritize speed. Privacy-first users. Anyone tired of their browser eating RAM.

Arc features it replicates:

Built-in privacy (Brave doesn’t need extensions like uBlock Origin)
Tab organization (not as visual, but functional)
Tab stacking (vertical stacks are available)
Minimal cruft—just works

What’s missing: Vertical sidebar. Spaces concept. The actual Arc user experience. Quick capture. But if Arc’s UX was secondary to its performance, Brave wins.

Price: Free | Platform: Windows, Mac, Linux

Vivaldi

For people who want to customize everything

The verdict: Vivaldi is Arc for power users who don’t mind tinkering. It has vertical tabs, tab stacking, workspace-like features, split-view, AND native email/calendar. It’s feature-complete to the point of being overwhelming.

Best for: Users who want to customize every pixel. People who need email/calendar integration. Arc users who want more features, not fewer.

Arc features it replicates:

Vertical sidebar with full customization
Tab stacking and grouping (more robust than Arc’s)
Workspaces (called “Sessions” in Vivaldi)
Split-view websites side-by-side
Built-in notes, mail, calendar

What’s missing: Arc’s simplicity. Vivaldi has 200 settings where Arc had 5. Slightly slower than Brave/Chrome. The UI philosophy is “give users control,” not “give users elegant simplicity.”

Price: Free (with premium for advanced features) | Platform: Windows, Mac, Linux

🔐

Firefox

The OG privacy browser, still solid

The verdict: Firefox won’t feel like Arc, but it’s the most trustworthy alternative. Mozilla’s privacy track record is unmatched. Firefox is catching up on performance (it’s much faster than it was in 2023), and the extension ecosystem is nearly as robust as Chrome’s.

Best for: Users who want to escape Google entirely. Privacy-first users. Open-source believers.

Arc features it replicates:

Tab grouping (via native features or extensions)
Privacy built-in (no tracking by default)
All Chrome extensions work (via webextensions API)
Customizable UI

What’s missing: Everything Arc’s design philosophy stood for. Firefox is tab-based, not spatial. No vertical sidebar by default (can be added via themes). No Spaces equivalent. Performance is good, not great.

Price: Free | Platform: Windows, Mac, Linux

💼

Google Chrome

The baseline, plus extensions can fill gaps

The verdict: Chrome alone isn’t an Arc replacement. But Chrome + four well-chosen extensions gets you to 85% of Arc’s functionality. If you’re already in the Google ecosystem and don’t want to context-switch, this is the path of least resistance.

Best for: Users who need perfect Gmail/Google Workspace integration. Web app users. The extension ecosystem is unbeatable.

Arc features it replicates (via extensions):

Vertical tabs (use Sidebarr or Tab Master Plus)
Workspaces (Chrome’s native Profiles + extensions like Workona)
Tab organization and stacking (multiple extensions handle this)
Quick capture (use Built-in screenshots + Notion clipper, or Evernote clipper)

What’s missing: The integrated, polished experience. You’re gluing together separate tools instead of using a cohesive browser design. Performance impact from extensions (every extension is a memory cost).

Price: Free | Platform: Windows, Mac, Linux, Chromebooks

🤖

Opera One

The AI sidebar browser that nobody talks about

The verdict: Opera One is criminally underrated. It has vertical tabs, workspaces, built-in AI sidebar (powered by OpenAI), and a free VPN. It won’t win awards for design, but it’s a legitimate Arc alternative if you want a different angle on productivity.

Best for: Users who want AI integrated into their browser. Tab hoarders who like vertical organization. Anyone who wants a functional free VPN.

Arc features it replicates:

Vertical sidebar with tab organization
Workspaces
Built-in AI (different from Arc’s approach, but useful)
Free VPN (Arc didn’t have this)
Tab stacking

What’s missing: The design polish. Opera One feels like it was made by engineers for engineers, not designers for users. No split-view. Quick capture isn’t as smooth.

Price: Free | Platform: Windows, Mac, Linux

🏗️

SigmaOS

Arc’s spiritual successor (if you’re on Mac)

The verdict: SigmaOS is new (launched 2024) and Mac-only. It was designed by ex-Arc team members and takes Arc’s spatial philosophy further. If you’re deeply invested in the Arc vision and stuck on macOS, this is your best option.

Best for: Mac users who want Arc’s design philosophy continued. Users who embrace a completely redesigned browser paradigm. Niche productivity enthusiasts.

Arc features it replicates:

Spatial tab organization (even more advanced than Arc)
Workspaces and collections
Sidebar-first navigation
Customizable quick actions
Native split-view

What’s missing: It’s new. Stability and extension ecosystem aren’t proven yet. Mac-only means 50% of potential Arc users are out. Performance is smooth but not tested at scale.

Price: Free (with $5/month premium) | Platform: Mac only (Windows announced but not released)

Building “Arc” Inside Chrome: The Extension Stack

If you’re already deep in the Google ecosystem or just can’t leave Chrome, you can get surprisingly close to Arc by stacking extensions. Here’s the setup I tested for two weeks:

The Chrome-as-Arc Stack

Sidebarr — Vertical sidebar with tab management. Closest to Arc’s layout.
Workona — Workspaces for organizing projects. Not identical to Arc Spaces, but functional.
Tab Master Plus — Advanced tab organization and search (backup to Sidebarr).
Notion Web Clipper — Quick capture alternative (Arc didn’t have native note integration, so this is actually better).
Chrome Split Screen — Side-by-side view for two tabs.

The verdict: This stack gets you 80% of Arc’s functionality in Chrome. Total memory overhead: roughly 50MB per extension (negligible if you have 16GB+ RAM). The experience isn’t as seamless as Arc was, but it’s workable for 3-6 months while you figure out your long-term browser home.

My 3-Month Verdict: Which Browser I’m Actually Using Daily

After 90 days of testing, I’ve landed on a hybrid approach: Zen for work, Brave for daily browsing.

Zen gives me the Arc-like environment I need for focused work—vertical tabs, collections, the spatial organization that makes sense to my brain. But Zen is slightly slower for general browsing and YouTube. So I use Brave as my “daily driver” for casual browsing, shopping, and streaming. The speed difference is noticeable, and Brave’s built-in privacy means I don’t need to install any extensions.

For the 20% of my workflow that needs split-view or intense customization, I’ll occasionally boot up Vivaldi. But it’s not my default—it’s my “when Zen/Brave aren’t enough” tool.

Bottom line: No single browser perfectly replaces Arc. But Zen gets you 85% there, and if you’re willing to live without Arc’s exact UX, Brave or Vivaldi will serve you better in most ways that actually matter (speed, privacy, stability).

Frequently Asked Questions

Is Arc truly shutting down? Can I still use it?

Arc isn’t shutting down immediately, but The Browser Company is in maintenance mode. You can still use Arc, but don’t expect new features. It will likely become increasingly buggy and outdated as web standards evolve. Plan to migrate within 12 months.

Will Arc 2.0 be worth the wait?

Maybe. The Browser Company says Arc 2.0 will be AI-native and launch in late 2026. But given how long Arc 1.0 took to build and ship, I wouldn’t count on it. Best to find an alternative now and revisit Arc 2.0 if it impresses you at launch.

Can I use two browsers at once?

Yes. Use Zen for focused work, Brave for casual browsing. Or Vivaldi for everything if you want one tool. Multiple browsers isn’t heresy—it’s pragmatic. Arc users already did this (they had Arc for work, Chrome for Google stuff).

Which browser uses the least RAM?

Brave, by a significant margin. It’s about 15-20% lighter than Chrome and Vivaldi. Zen and Firefox are comparable to Chrome. Opera is surprisingly lean. SigmaOS and Arc were memory-hungry on purpose (spatial design requires more overhead).

Can I sync Arc data to a new browser?

There’s no built-in migration tool. You can export Arc’s history and bookmarks via Settings > Export, then import to most other browsers. Spaces, quick capture, and visual organization don’t export cleanly. Plan on rebuilding your workflow manually.

Ready to Leave Arc?

Start with Zen Browser if you want Arc’s design language. Switch to Brave if you want pure speed and privacy. Or go all-in on Vivaldi if you want to customize every detail. Whatever you choose, commit for 30 days before switching again—it takes time to build muscle memory with a new browser.
