The best anti-detect browser for Facebook ads, by what you run

We make Mosaic. We tried to be fair; corrections to hello@mosaicbrowser.com.

Most rankings of the best anti-detect browser for Facebook ads are written by people selling one, and almost none of them start where Meta does. So we start there. Meta's rules decide which accounts you may run; the browser only decides how cleanly you keep them apart.

What Meta allows, before any browser

Meta's Terms of Service ask each person to "create only one account (your own) and use it for personal purposes", and not to share a password or give others access to their Facebook account. Advertising for several businesses happens one level up, in Business portfolios. Meta's Business Help Center says a person can personally create up to 2 business portfolios, that all advertisers start with an ad account limit of one until they make a confirmed payment, and that Meta adjusts the limit based on spending and the use of existing ad accounts. An agency gets into a client's ad accounts through partner access to the client's portfolio, signing in as itself. (All read on 2 November 2026.)

Mosaic keeps accounts you are entitled to run apart; it does not change what a platform allows. The same Terms say that if Meta disables your account, you don't create another one without its permission, so any browser sold as a way back in after a ban is sold for breaking them. That use is not one we write for, and Mosaic is not built for it.

So what is the browser for?

If one person can only have one Facebook login, why would a media buyer want separate profiles at all? Because the Facebook login is a small part of the job. A buyer working for six clients also holds six Shopify admins, six landing-page builders, six tracking dashboards and six inboxes for the billing alerts, many of them with no agency mode, and each with a two-factor code. Mixing those in one Chrome is how a pixel ends up on the wrong store. Separate profiles also let you see each client's ads and landing pages from the client's own market, which is checking ads in other countries rather than guessing.

That gives the criteria we used:

1. Each profile keeps its own cookies, storage and fingerprint, read the same way by every frame of the page.
2. Each profile gets its own exit in the client's market, with timezone and language following it.
3. Two-factor codes live with the profile they belong to.
4. Automation exists for reporting and routine checks, if you want it.
5. The price fits how many clients you carry and how many people do the work.

How it works: Provider minting

The best anti-detect browser for Facebook ads, compared

Facts from each vendor's own pages, read on 2 November 2026. "See vendor" means the page we read did not say.

	Free plan	Paid entry	Team members	Automation	Proxies
Mosaic	3 profiles, 10 creations	$49/mo, unlimited	No	REST API, MCP, CDP	Bring your own; providers mint a session per profile
Dolphin{anty}	Up to 3 profiles	$10/mo, 20 profiles	Yes, paid per user	Synchronizer, scenarios, API on paid	See vendor
AdsPower	2 profiles	Priced by profile count	Yes	RPA, synchronizer, local API	See vendor
Multilogin	5 cloud profiles	$11/mo, 10 profiles	Yes	API	Premium proxy traffic included
GoLogin	3 profiles	$9/mo, 10 profiles	Yes	REST API on paid	GB of residential proxy listed

Dolphin{anty}

Dolphin is built around media buying, and its home page shows it. It lists a synchronizer and scenario automation, and team permissions that reach individual profiles and folders. The pricing page shows Free with up to 3 profiles and no API, Starter at $10 a month for 20 profiles, and Base at $89 for 100, with extra users at $10 to $25 each depending on the plan. A team of buyers who split client folders between them is who it was made for.

AdsPower

AdsPower's pricing page puts an RPA robot first, with workflows you build from blocks, then a synchronizer and a local API. Free is 2 profiles. A Monday routine of opening each client's Shopify admin and saving last week's orders report is the kind of click-path you would draw here rather than script.

Multilogin

Every plan includes premium proxy traffic and mobile minutes for cloud phones, which matters if the client's work includes the Facebook or Instagram mobile apps. Free is 5 cloud profiles with no time limit; Pro starts at $11 a month for 10 profiles; Business starts at 100 profiles with unlimited team seats.

GoLogin

A low entry price: $9 a month for 10 profiles on Professional, with a REST API on paid plans and some residential proxy traffic listed on each tier. Business is $99 a month for 300 profiles.

Where Mosaic fits for ad work

Mosaic is for one buyer, or a small shop on one machine, who wants every client's browser apart and nothing in anyone's cloud.

Each profile runs on Tesseract Chrome, our own Chromium, with fingerprint values changed in C++ inside the engine, so the page, its iframes and its workers read one machine. The hardware comes from records of real machines, and the timezone, language and location follow the proxy's measured exit. Save your proxy seller as a provider by pasting one gateway line, and each client's profile mints its own session, so two clients never share an exit by accident. A profile does not open behind a proxy that has not answered and tunnelled; the launch stops and says which check failed.

Two-factor codes are kept per client. Each profile has its own credential vault with TOTP codes, and the companion inside that profile's browser lists that client's logins and codes and nobody else's. On Pro, POST /api/v1/profiles/:id/start returns a CDP endpoint that Puppeteer or Playwright attach to, so a weekly report script can open each client's signed-in dashboard in turn.

What Mosaic lacks for ad teams: team seats, a cloud copy of profiles, cloud phones and any proxy traffic of its own. If three buyers share one client list across three laptops, Dolphin{anty} or Multilogin fits that better. The day-to-day setup for agencies is in ad account management with Mosaic, and the wider field is in the best anti-detect browsers.
