What Multilogin does, and who you are contracting with

An antidetect browser answers one question: how do you run twenty accounts from one laptop when the platform is fingerprinting your laptop? Multilogin's answer is a profile. Each profile carries its own canvas and WebGL values, its own font list, its own cookie jar, its own proxy, and a timezone and language that match the exit IP. To the site, each one looks like a different computer in a different city.

The product you buy in 2026 is Multilogin X, launched in 2024 with a web interface and an API-first design. The old desktop app, Multilogin 6, is closed to new subscriptions and exists only for users who have not migrated. If a review you read describes a downloadable desktop suite with a €29 entry plan, it predates the rewrite and its prices are worthless.

One detail almost nobody mentions, and it matters more for a privacy tool than for most software: you are not contracting with an Estonian company any more. Multilogin started in Estonia in 2015 as Multilogin Software OÜ, and that entity still exists on the register. But the terms of service and privacy policy published on multilogin.com, checked on 26 July 2026, name Eyes of Wonder Software LLC of Business Bay, Dubai, and state that the contract is governed by the laws of the United Arab Emirates with disputes heard only in UAE courts.

Read that as a practical fact, not a scandal. Your cloud-stored profiles, which include live session cookies for every account you run, sit with a UAE entity, and your legal recourse if something goes wrong runs through Dubai rather than an EU member state. If that is fine for your use case, carry on. If you are handling client accounts under a GDPR data-processing agreement, it is a conversation to have with your lawyer before it is a conversation to have with sales.

Mimic, Stealthfox, and the engine that stopped

Multilogin ships two browser cores. Mimic is Chromium-based and is what the documentation tells you to use for essentially everything: modern sites, extensions, automation. Stealthfox is Firefox-based, and every affiliate review on the internet sells it as the dual-engine advantage that justifies the price.

Multilogin's own help documentation disagrees. Stealthfox is described there as a legacy core that will not receive new core updates, with no versions planned after v146. The advice is to use it only if a workflow still depends on Firefox behaviour or a Firefox extension.

A frozen browser core is not a neutral fact in this category. Fingerprinting surfaces move with browser releases, and a core that stops tracking upstream Firefox drifts further from a plausible real-world signature every month. Treat Multilogin in 2026 as a one-engine product with a Firefox option kept on life support, and judge the price on Mimic alone.

On how well Mimic works: independent testing by Proxyway found profiles passing Pixelscan consistently and scoring in the low-to-mid 70s on CreepJS, which is respectable. The same testing found scores dropping sharply when the profile's declared operating system did not match the underlying host. The tool rewards correct configuration and punishes casual use, which is worth knowing before you assume a default profile is safe.

Pricing: the worst profiles-per-dollar at the bottom

Prices below are from multilogin.com/pricing, checked on 26 July 2026, in USD. Annual billing runs about 35% below the monthly rate.

• Free: 5 cloud profiles, no card required, API included, with 200 MB of proxy traffic and 30 mobile minutes as a one-off. The catch is buried in the plan details: profiles are deleted automatically if you do not start one for 7 days.
• Pro 10, $11/mo ($85 a year): 10 profiles, 1 seat, 1 GB proxy traffic, 60 mobile minutes.
• Pro 50, $29/mo ($230 a year): 50 profiles, 1 seat plus one more, 3 GB.
• Pro 100, $40/mo ($320 a year): 100 profiles, 2 seats, 5 GB.
• Business, from $89/mo ($685 a year) for 300 profiles, on a slider up to 10,000 profiles at $900/mo ($4,285 a year). Unlimited team seats, 10 GB of proxy traffic a month.

Compare the entry tier against the rest of the market and Multilogin looks bad. Eleven dollars buys 10 profiles here; GoLogin's $24 plan carries 100 and Dolphin Anty's $10 Starter carries up to 60.

The picture inverts at the top. Business is the only plan in this comparison with genuinely unlimited team seats. Dolphin Anty charges $159 a month for 300 profiles and then $10 for every extra user; Octo Browser's 600-profile tier caps you at six members. A six-person agency on Multilogin Business pays $89 a month flat. That, not the fingerprinting, is what the price is actually buying.

Seat allocation on the lower plans is the trap. Pro 10 and Pro 50 are single-seat products. The moment a third person needs access, the ladder jumps from $11 or $29 straight to $89, because there is no per-seat add-on to bridge it.

Automation, proxies and the running costs

Multilogin X made one genuinely good decision: the API is on every paid plan, including the $11 one. In Multilogin 6 automation was gated behind a custom enterprise contract, and Octo Browser still gates its API behind a €79 tier. Rate limits are 50 requests a minute on Pro 10 and 100 on everything above, shared across the whole workspace rather than per user.

Selenium, Puppeteer and Playwright all work, with one constraint that costs people an evening: they must connect over Multilogin's remote WebDriver endpoint. Point a local WebDriver at it and the automation breaks.

Proxies are the running cost nobody budgets for. Multilogin sells residential traffic on top of the subscription and the bundled allowance is small, from 1 GB on Pro 10 to 10 GB on Business. Extra traffic is $3.50 per GB, mobile minutes are $0.011 each. Ten profiles doing real browsing will pass 1 GB quickly, so the $11 plan is realistically $20 to $30 a month unless you bring your own proxies, which is fully supported over HTTP, HTTPS, SOCKS4 and SOCKS5.

Three more terms worth having in front of you before you pay:

• There is no money-back guarantee. The terms of service refund only outages lasting more than 24 hours that were Multilogin's fault, plus a pro-rata refund of unused time on request. Some reviews still cite a 14-day guarantee; it is not in the current terms.
• Crypto payments do not auto-renew. Card, Apple Pay and Google Pay renew as expected. Crypto, VietQR, SberPay and YooMoney require you to pay each invoice manually. American Express is not accepted.
• Data is kept for three months after a subscription ends, and a missed payment suspends the account with the profiles still on Multilogin's servers.

What the fingerprint does not cover

This is the section most reviews of antidetect browsers skip, and it is the one that decides whether you keep your accounts.

Multilogin hides the fingerprint. It does not hide behaviour, and it does not hide the identity documents behind the accounts. Platforms link accounts through payment methods, shipping addresses, phone numbers, tax details, support tickets, and timing patterns. None of those pass through a browser core.

Meta's account integrity policy prohibits accounts created to evade a previous removal and networks of accounts under common ownership acting with a violating purpose. Amazon permits multiple seller accounts for a genuine business need, but links them, and a deactivation on one can cascade across all of them. Multilogin's own terms are silent on multi-accounting while its marketing pages display the logos of Amazon, Facebook, TikTok, Binance and a dozen other platforms, which is a gap you should read clearly: the compliance risk is entirely yours, and a ban comes with no refund.

The uses that are straightforwardly defensible are the boring ones. Agencies operating client accounts they are authorised on. QA and cross-browser testing. Ad accounts separated under one verified business entity. Price and SERP monitoring. Keeping work and personal sessions genuinely apart. If your plan needs a paragraph of justification, the fingerprint is not your biggest problem.

Against AdsPower, GoLogin, Dolphin Anty and Octo

The category is crowded and the differences are real:

• AdsPower: a free tier with 2 profiles and cheaper entry pricing, plus RPA tooling for repetitive tasks. The usual first stop for solo affiliates.
• GoLogin: $24 a month for 100 profiles and a 7-day trial. The best profiles-per-dollar at the entry level by a wide margin.
• Dolphin Anty: $10 for up to 60 profiles, popular with media buyers, but Starter is locked to a single user with no way to add another.
• Incogniton: $13.99 for 10 profiles, with a permanently free 3-profile tier.
• Octo Browser: €10 for 3 profiles, no free tier, and no API until €79 a month. Reputation for strong fingerprints, priced accordingly.

Reputation data is thin and awkward. Multilogin holds 4.8 on G2 across about 90 reviews and 5.0 on Capterra across 67, both checked on 26 July 2026. A perfect 5.0 across 67 reviews on a paid-listing directory deserves scepticism, and Trustpilot, where the free-text reviews are considerably harsher, blocked access when this review was written. The complaints that recur in what is readable: service outages, occasional fingerprint instability, support that is either excellent or absent depending on who answers, and the price. The praise is consistent about two things, the built-in proxies and profiles that survive for years without trouble.

Verdict: who should buy it

Buy Multilogin Business if you are an agency or a team of three or more sharing profiles. Unlimited seats at $89 a month is the cheapest way to give six people managed access to 300 profiles, the API is included at every tier, and the fingerprinting holds up when configured properly. The role controls and 2FA are also the best in this group, which matters when a departing contractor has been logging into client accounts.

Do not buy Pro 10. At $11 for 10 profiles and a single seat, it is the weakest offer on this page. A solo operator gets 100 profiles from GoLogin for $24, or 60 from Dolphin Anty for $10, and neither charges you extra to reach a workable number. Multilogin's entry tier only makes sense as a paid trial before committing to Business.

And if you are shopping for privacy rather than for multi-accounting, this is the wrong shelf entirely. A profile-isolating browser is an operations tool for people running many accounts. For keeping your own browsing private, a VPN and a hardened browser cost a fraction of this and are built for the job.
