What Is Tao Browser? The Beginner's Guide to the WebKit Browser for Founders

What Is Tao Browser?

Tao Browser is a free, private web browser for founders, built by the small hosting company Hostao on Apple's WebKit engine. In one sentence, what is Tao Browser?

It is a browser that gives every company, client, or project its own space, and every space keeps its own cookies and logins. Two Google Workspace accounts can sit side by side without colliding, and the right Gmail, Stripe, and GitHub accounts are already signed in when you switch spaces.

The browser comes from Reji, the founder of Hostao, who built it after The Browser Company announced that Arc stops working on 22 December 2026. He juggled many company accounts every day and wanted his Arc-style spaces back without an account, an AI-everywhere pivot, or a profile switcher that makes you log out and back in all day. He wrote the story up in a Medium post on 5 November 2026, three days after the Product Hunt listing went live on 2 November 2026.

Tao Browser is free on the App Store for iPhone and iPad, and a free beta for Mac. There is no account, no ads, no analytics, and no crash reporting.

The Mac download is about 7 MB (6.9 MB per the vendor site), because the engine is the WebKit already on your Mac. If you want to confirm any download before you run it, a SHA-256 hash generator gives you the file's fingerprint in seconds. Hostao is a small hosting company, so the browser comes from people who run VPS hosting for a living.

Why Did a Founder Build a Browser at All?

Founders rarely run one company. A typical day mixes a startup inbox, a consulting client, a side project, and a personal account, and each one has its own Gmail, Stripe, and GitHub login.

A normal browser keeps one set of cookies per profile, so switching companies means switching profiles or logging out and back in all day. That friction is small each time, but it repeats dozens of times a day.

The cost of getting it wrong is worse than the friction. Sending a client email from your startup's mailbox, or charging a payment to the wrong Stripe account, is the kind of mistake that takes a week to undo.

Reji says he built the Wrong-Account Guard because he nearly sent from the wrong mailbox once. The browser exists to make that mistake hard to make.

Arc solved this problem for Mac power users with Spaces, and its shutdown left those users looking for a home. Tao Browser is one answer, and it is deliberately small: no account, no AI-everywhere pivot, and no profile switcher. It brings back spaces, and it adds a guard against sending from the wrong account.

The funding model is part of the pitch. Hostao funds the browser from its hosting business, and the maker writes that the browser is not the product, so there are no ads and no data collection.

That is why the price is zero with no in-app purchases, and why there is no account to create. A browser paid for by ads would need your attention, and a browser paid for by a subscription would need your card. Tao Browser needs neither, because its maker already runs a business that pays for it.

How Do Spaces With Separate Logins Actually Work?

Every company, client, or project gets its own space in Tao Browser. Each space keeps its own cookies, logins, website storage, pinned tabs, folders, and start page.

Your startup, your consulting work, and your side project each live in a separate space, so the right accounts are already signed in when you switch. No more asking which account this is.

Under the hood, each space is backed by its own WebKit website data store. That is real separation, not a tab group with a colour.

Cookies and site data never mix between spaces, so two Google Workspace accounts or two Stripe dashboards sit side by side without colliding. The maker's own example is simple: mail for Hostao opens in the Hostao space, already signed in, while a client's Google Workspace sits in its own space next to it, with a different account and no collision.

Spaces are the whole idea. Everything else in Tao Browser, from the command bar to the screen-sharing mode, exists to make living in several spaces feel calm instead of chaotic. That is the Tao Browser spaces separate logins model in one line: one company, one space, one set of logins.

What Is the Wrong-Account Guard?

The Wrong-Account Guard compares the Gmail, Outlook, or Zoho account label with the space you are in, and it warns you before you send from the wrong company's mailbox. If you are signed in with Company A's account while you are in Company B's space, Tao shows a bar with "Open in Company A", and Gmail's Send asks first. Tao learns which account belongs to which space the first time it sees it, and it reads only the account label, never your mail.

This is the feature that separates Tao Browser from a plain profile switcher. A profile switcher changes which account is active, but it cannot tell you that you are about to send from the wrong one.

The guard watches the send moment itself, which is the last moment the mistake can still be caught. For a founder who sends client mail all day, that one check is worth more than a dozen small conveniences.

Why WebKit Instead of Chromium?

Tao Browser is built on Apple's WebKit, the engine already shipped with macOS and iOS, instead of Chromium. The reason is maintenance.

A small team cannot safely maintain a Chromium fork on a four-week security cycle, so Tao uses the WebKit already on your Mac. Apple ships the engine security fixes with the operating system, and the maker owns only the shell around it.

The choice also explains the download size. The Mac app is about 7 MB because it does not ship an engine of its own.

A Chromium-based browser has to carry its engine with it, which is why those downloads are hundreds of megabytes. Tao Browser's small size is a side effect of a security decision, not a marketing trick.

The Tao Browser WebKit choice is a maintenance decision before it is a performance one. A four-week Chromium security cycle would demand a team the maker does not have, while WebKit lets Apple carry that load.

The cost is extension choice, and the benefit is a browser a small team can keep secure for years. That trade is the right one for a product whose whole pitch is calm reliability.

There is a trade-off, and the maker states it plainly. Extension support in WebKit is narrow, so Tao ships a small reviewed set instead of the Chrome Web Store. The next section covers what that means, and the limits section covers it again, because it is the one compromise most Chrome users will feel.

What Can You Do With the Command Bar and the Sidebar?

Press Command-K and the command bar opens. From it you can open sites, search, switch tabs and spaces, pin tabs, open private tabs, open a split view, and start the Arc import. It is the fastest way to move around the browser, and it is how a founder with five spaces jumps between companies without touching the mouse.

The Smart Sidebar, new in version 1.3.1, keeps the sidebar out of your way. Tabs hide while you type, scroll, watch, or take a call, and they slide back when you pause. Each site and each space remembers its own sidebar setting, so a reading space can stay quiet while a working space keeps its tabs visible.

Split view puts two pages side by side in one window, which suits comparing a client brief with a dashboard, or a document with the email that describes it. Client Mode, toggled with Shift-Command-M on Mac, hides other tab titles, pinned tabs, history in search, password prompts, and dashboards while you screen-share. Sites you marked confidential stay covered until you click them, and on iPhone and iPad the mode turns on automatically when the screen is recorded, mirrored, or AirPlayed.

What Else Is Inside Tao Browser?

Site Watch turns your start page into a small status board for your own sites. It shows whether each site is up or down, its response time, and the days left until its SSL certificate and domain expire.

The checks go straight from your device to the site and to the domain registry, with no Tao server in between. For someone who runs client sites, that is a quiet early warning system.

Company Cards keep each space's business details close at hand. A card holds the company's legal name, registered address, VAT, TRN, GSTIN, EIN, and company number.

Autofill uses the card of the space you are in, including tax fields that normal autofill skips. That is a small feature with a large payoff when you fill in invoices and tax forms for several companies.

The built-in ad and tracker blocker compiles 111,722 rules from EasyList and EasyPrivacy into WebKit's content blocker, and the blocking happens on your device. You can switch it off per tab when a site breaks.

Face ID or Touch ID can lock a single tab, a whole space, or the whole app. The built-in password manager saves to macOS Keychain, fills with Touch ID or your Mac password, imports CSV files from Chrome, Safari, Bitwarden, and 1Password, and checks breaches through Have I Been Pwned using k-anonymity, which sends only the first five characters of a password hash. Passkeys are coming.

The AI page panel, new in version 1.4, can summarise a page, pull out key points, draft a reply, scan a competitor, or extract contacts and pricing. You bring your own API key, with Google Gemini as the default, and OpenAI, Anthropic Claude, OpenRouter, Mistral, Groq, DeepSeek, any OpenAI-compatible server, or local Ollama and LM Studio as options.

Nothing is sent until you click, keys stay in macOS Keychain, each space can use its own provider and key, you can mark a site as never send, and the panel stays off in private tabs. Gemini 4 Argon is the default model behind that panel, and what an AI browser is explains the wider category Tao is deliberately not joining.

How Do You Import Arc Into Tao Browser?

Moving from Arc takes one click, and the clock matters. Arc stops working on 22 December 2026, which is 46 days from today, 6 November 2026.

The import reads Arc's files while Arc is still on your Mac, so doing it early is better than doing it on the last day. The vendor site says it plainly: import your spaces and pinned tabs into Tao while Arc is still on your Mac.

1. Keep Arc installed on your Mac, and install Tao Browser beta 1.4.2 from tao.hostao.com.
2. Press Command-K to open the command bar.
3. Choose "Import from Arc" from the command bar.
4. Let Tao read Arc's sidebar file on your Mac and recreate your spaces, pinned tabs, folders, and favourites.
5. Check each space, then keep using Arc until you are sure nothing is missing.

Nothing in Arc is changed by the import, and nothing is uploaded anywhere. Tao also imports bookmarks from Chrome, Brave, and Arc, so a mixed history still lands in one place. The whole point is a move without a migration project, and the five steps above are the whole project.

What Is the Arc Shutdown Timeline?

The Browser Company announced the Arc sunset on Thursday, 22 October 2026, and pointed users to Dia, its AI-first successor. The wind-down is staged over 61 days, from the announcement to the final shutdown, and each stage takes something away.

The company gave rising security costs in the age of AI as the reason, and its engineering and security focus moves to Dia. Atlassian had acquired The Browser Company for $610 million in 2025.

The gap between the last two stages is 29 days, so the final month is the real deadline, not a grace period. The first stage lands 32 days after the announcement, so the AI switch-off arrives about a month in.

The maker's Medium post went live 47 days before the shutdown, which is why the migration hook feels urgent rather than theoretical. If you still run Arc, the import above is the cheapest way to keep your setup.

Tao Browser vs Arc vs Dia vs Zen

Every Arc alternative answers the same question differently, and the right one depends on what you loved about Arc. As a Tao Browser Arc alternative, it keeps the spaces model without the AI-first pivot.

Dia is the official answer: The Browser Company's own AI-first browser, which carries Arc's Spaces over as Profiles and its Folders over as Pinned Tab Groups. Zen Browser is the open-source answer: a Firefox-based browser with workspaces, covered in our how to use Zen Browser guide. Arc itself is the answer that ends on 22 December 2026.

The table shows the trade-offs clearly. Tao Browser wins on separate logins and lightness, and it loses on extension choice and platform range.

Dia wins on being the official path with full Arc import, and it loses on being AI-first when you wanted the opposite. Zen wins on openness and platforms, and it loses on the one-click move and the separate-login model. A founder who runs several companies will feel the spaces difference every day, while a user with one account may never notice it.

What Are Tao Browser's Honest Limits?

Tao Browser is proprietary, not open source, and the maker says so on the first page of the story. The third-party pieces it uses, like EasyList and Sparkle, are listed with their licences on the site, but the browser itself is closed. That matters if you only run open-source tools, and it does not matter at all if you only care what the browser does.

The extension set is small by design. On Mac, version 1.4 adds a one-click gallery with uBlock Origin Lite, Dark Reader, and Bitwarden, and it needs macOS 15.4 or later.

On iPhone and iPad, iOS 18.4 or later gets the first two. Permissions are shown in plain words before you add anything, each extension downloads from the publisher's official release and must match the exact reviewed version, and Tao can also find extensions you used in Brave, Chrome, Edge, Vivaldi, or Arc and add the supported ones. There is no Chrome Web Store, and some Chrome-only extensions will not work in WebKit, so check your must-have extension before you switch.

There is no sync between devices yet, and everything stays on your device. There is also no Windows or Android version today, and both are planned with no dates.

The Mac app is a free beta downloaded directly from the vendor site, with the Mac App Store version in review. None of these limits is hidden, and the maker lists them in the same post that introduces the browser, which is the right way to earn trust for a new product.

Should You Try Tao Browser, or Wait?

The answer depends on how many companies you run and which devices you use. Tao Browser fits a founder or freelancer on a Mac, iPhone, or iPad who juggles several companies and wants separate logins without an account.

It fits less well if you live on Windows, switch devices all day, or depend on a Chrome-only extension. No CodexFuse Tao Browser tool exists, and this article promises none.

The Tao Browser Mac iPhone story is simple: the Apple devices most founders already carry are the ones Tao runs on today. The Mac beta is a free download from the vendor site, and the iPhone and iPad versions are already on the App Store.

Windows and Android are planned with no dates, so the browser is, for now, an Apple-only product. That focus is also why it can be so small: one engine, one platform family, and one clear audience.

Tao Browser is a small bet on a simple idea: a browser should know which company you are working for. The product is six days old on the public record, from a vendor site published 31 October 2026 to a maker post on 5 November 2026, so it is early.

But the problem it solves is real, the price is zero, and the import takes one click. For a founder with several companies and a Mac, that is enough reason to try it before Arc stops working.

Frequently Asked Questions

What is Tao Browser in simple terms?

Tao Browser is a free web browser for founders, built by Hostao on Apple's WebKit. It gives every company, client, or project its own space, and every space keeps its own cookies and logins, so two Google Workspace accounts can sit side by side without colliding. It runs on Mac as a free beta and on iPhone and iPad from the App Store.

Is Tao Browser really free?

Yes. The vendor site says it is free, with no account and no ads, and the Product Hunt listing shows a price of zero dollars with no in-app purchases.

There is no paid tier, subscription, or price on any source fetched for this article. Hostao funds the browser, and the maker writes that the browser is not the product, so there are no ads and no data collection.

Does Tao Browser replace Arc?

It is one replacement for Arc, not the official one. Dia is The Browser Company's official AI-first successor, and Tao Browser is an independent alternative for people who wanted Arc's spaces without an AI-first browser. Tao imports Arc spaces, pinned tabs, folders, and favourites in one click, and Arc stops working on 22 December 2026, so the move has a real deadline.

Why does Tao Browser use WebKit instead of Chromium?

A small team cannot safely maintain a Chromium fork on a four-week security cycle. Tao uses the WebKit already on your Mac, iPhone, and iPad, so Apple ships the engine security fixes with the operating system and the maker owns only the shell. The trade-off is narrow extension support: a small reviewed set instead of the Chrome Web Store.

Can I use Tao Browser on Windows or Android?

Not today. Tao Browser runs on Mac as a beta, and on iPhone and iPad from the App Store.

Windows and Android versions are planned, with no dates yet, and sync between devices is still missing. If you work only on Windows or Android, wait for those versions rather than switching now.
