XDA just ran a write-up on Perplexity’s Comet browser driving both Mac and PC workflows, and the takeaway lines up with what a lot of us have been hearing: Comet is useful, but the Pro price tag and the way it hooks into every open tab feels heavy once you look past the demo. The agent that reads your email drafts and shopping carts is also the agent watching every private tab, and Perplexity’s own pricing changes have made the calculus tighter. If Comet’s promise sounds right but the trade-offs don’t, there are Perplexity Comet alternatives worth a look on Windows, macOS, and Linux.
We tested seven Perplexity Comet alternatives across a M3 MacBook Air, a Windows 11 desktop, and a Fedora laptop. Each pick is judged on how well the AI actually helps with real research and browsing, not staged demos, and on how much data leaves your machine to get there.

Why people look past Comet in 2026
Comet is polished but the price and the platform lock-in are real. A recurring complaint on Reddit is that Perplexity’s Pro plan is a hard $20/mo requirement to keep the agent from throttling, and that the browser hoovers up context whether you asked for it on that tab or not. Users on Hacker News have flagged that Comet’s Mac build gets attention while Linux support drifts behind. There are three patterns we heard again and again:
- Subscription pressure. Comet’s most useful agent behavior is behind the Pro plan, and Perplexity has been quick to expand the paywall.
- All-in privacy posture. The agent reads what you’re doing to help. Turning that off cripples the app; leaving it on means every tab is fair game.
- Chromium fatigue. Some users specifically wanted a break from Google’s engine and want a Firefox or open-source route.
The alternatives
Arc — Best for split-view research
Arc from The Browser Company is the fluent, tab-obsessed browser that got most creators hooked before Dia arrived. Spaces let us keep research, work, and personal browsing in separate columns, and Split View shows two or three tabs side by side without a second monitor.
Where it falls short: The Browser Company has publicly shifted its focus to Dia, and Arc’s development pace has slowed. There’s still no Linux build.
Pricing:
- Free: Fully free, no ads.
- Paid: None.
- vs Comet: Free vs Comet’s Pro plan.
Migrating from Comet: Import your bookmarks, saved logins, and history from Chrome or Comet directly through Arc’s onboarding. Extensions carry over from the Chrome Web Store.
Download: arc.net
Bottom line: Pick this if you want the Arc experience while it still ships, and you don’t need a heavy AI agent baked into every tab.
Dia — Best for AI-first Chromium browsing
Dia is The Browser Company’s spiritual successor to Arc, built around a chat sidebar that reads the current tab and executes Skills you can share. It answers questions about the page, drafts emails from an open thread, and runs multi-step Skills across tabs.
Where it falls short: It’s still invite-based in some regions, and the paid Pro tier gates the heavier agent features. macOS only.
Pricing:
- Free: Preview access, limited chat quota.
- Paid: Pro $20/mo for full skills and higher limits.
- vs Comet: Same price ceiling with a cleaner tab UX.
Migrating from Comet: Dia imports Chrome and Comet profiles directly, including passwords and extensions. Skills are shareable URLs.
Download: diabrowser.com
Bottom line: The closest peer to Comet on macOS, and the better UX if you already trust The Browser Company.
Zen Browser — Best for open-source Arc-style browsing
Zen Browser rebuilds the Arc-style workspace layout on top of Firefox instead of Chromium. Workspaces, Compact Mode, and split panes are here without the tracking model of Chromium.
Where it falls short: No built-in AI agent. You’d pair it with an extension like Sider or a local model to match Comet’s chat sidebar.
Pricing:
- Free: Fully free, open source.
- Paid: None.
- vs Comet: Free, but you assemble the AI layer yourself.
Migrating from Comet: Import bookmarks and passwords through Firefox’s importer. Extensions come from the Mozilla Add-ons store.
Download: zen-browser.app
Bottom line: Pick this if you want the modern browser layout without a subscription, and you’re happy to add your own AI extension.
Brave Leo — Best for local AI without a subscription
Brave Leo is Brave’s built-in AI assistant that can point at a local Ollama endpoint instead of Anthropic or Mistral. Summaries, page Q&A, and follow-ups run entirely on your machine when you configure it that way, so nothing leaves the device.
Where it falls short: The bring-your-own-model setup takes a few minutes and needs a decent GPU. Leo’s page-context window is smaller than Comet’s.
Pricing:
- Free: Leo Basic with community models.
- Paid: Leo Premium $14.99/mo for Claude and larger context.
- vs Comet: Cheaper for the free tier, and the only option that runs offline.
Migrating from Comet: Import Comet profiles through Chrome import. Passwords and bookmarks transfer cleanly.
Download: brave.com/leo
Bottom line: The right pick if privacy comes first and you already run local models with Ollama or LM Studio.
Vivaldi — Best for power-user tab management
Vivaldi is the browser for anyone who wants to configure everything. Tab stacks, tiled tabs, notes, mail, calendar, and RSS live in the same window, and none of it phones home.
Where it falls short: No native AI agent. Vivaldi’s philosophy explicitly avoids server-side AI features.
Pricing:
- Free: Fully free, no telemetry.
- Paid: None.
- vs Comet: Free, but you trade an agent for control.
Migrating from Comet: Vivaldi imports Chrome and Chromium profiles including bookmarks, sessions, and passwords.
Download: vivaldi.com
Bottom line: Pick this if you’d rather manage tabs manually and skip the agent story entirely.
SigmaOS — Best for focused work sessions
SigmaOS wraps browsing in a workspace model that treats tabs like tasks. Airplane Mode silences a workspace, and the built-in Airis assistant summarizes and answers questions about the page.
Where it falls short: macOS only, and Airis is not as capable as Comet’s agent for multi-step tasks. The free tier caps AI calls per day.
Pricing:
- Free: Basic access with limited Airis usage.
- Paid: $8/mo Pro for unlimited Airis.
- vs Comet: Less than half the price of Comet Pro.
Migrating from Comet: Chromium-based, so bookmarks and extensions import from Comet directly.
Download: sigmaos.com
Bottom line: The pick if you keep separate work modes and want a lighter AI helper without paying full Comet Pro rates.
Chrome + Gemini — Best for Google account integration
Sometimes the answer is the browser you already use. Chrome + Gemini puts Gemini in the address bar, adds a side panel for chat, and hooks Gemini Live into pages. Nothing to install if you’re already in the Google ecosystem.
Where it falls short: The agent behavior is more like a smart sidebar than a true task runner. Deeper features (Deep Research, Advanced Voice) need Gemini Advanced.
Pricing:
- Free: Gemini in Chrome side panel.
- Paid: Gemini Advanced $20/mo bundled with 2 TB storage.
- vs Comet: Same $20/mo tier with tighter Google integration.
Migrating from Comet: No migration needed if Chrome is already your default. Import Comet profile as a Chrome profile.
Download: google.com/chrome
Bottom line: The best pick if your workflow already lives in Gmail, Docs, and Drive, and you don’t need an autonomous agent.
How to pick the right one
Pick Dia if you want the closest thing to Comet without leaving The Browser Company’s design language. It’s the direct peer.
Pick Brave Leo if privacy is the reason you’re leaving Comet. Point it at a local Ollama endpoint and the page context never leaves your machine.
Pick Zen Browser if you want a subscription-free open-source route and don’t mind wiring in your own AI extension.
Pick Vivaldi if you’re done with agents inside the browser altogether and want the best tab manager money doesn’t need to buy.
Stay on Comet if the multi-step agent (booking, filling forms, running Skills across tabs) is the whole reason you use a browser this year. Nothing else here matches that yet.
FAQ
Is Perplexity Comet worth $20/mo? For heavy research and multi-step agent tasks, yes. If your usage is closer to page summaries and search shortcuts, Dia’s cheaper tier or Brave Leo Premium covers the same ground.
What’s the best free Perplexity Comet alternative? Zen Browser paired with a Sider or WebChatGPT extension is the best free stack. Brave Leo Basic is the best free option that ships an AI panel out of the box.
Can I import my Comet setup into another browser? Yes. Comet is Chromium-based, so bookmarks, saved logins, and extensions transfer to any other Chromium browser (Arc, Dia, Brave, Vivaldi, SigmaOS, Chrome) through the standard Chrome importer.
Which alternative runs on Linux? Zen Browser, Brave Leo, Vivaldi, and Chrome all ship native Linux builds. Arc, Dia, and SigmaOS don’t.
Is there a Perplexity Comet alternative that runs AI locally? Brave Leo with a local Ollama endpoint is the direct answer. Zen Browser plus a Page Assist-style extension pointed at LM Studio or Ollama gets you the same result.
