Undetectable — antidetect browser: rating and member reviews

Undetectable makes one offer nobody else in the top tier matches: unlimited profiles stored on your own computer on every paid plan, from $49 a month. If you run hundreds or thousands of accounts on one machine, that's one of the cheapest ways to do it among the established antidetects. The fine print is in the cloud limits, the team pricing and a 2025 security analysis that showed how its browser could be spotted.

This review is built on what Undetectable publishes: its pricing page, changelog, documentation and FAQ, plus the public research about it, all checked on October 22, 2026. For how it compares with Dolphin, AdsPower, Octo and GoLogin on kernel updates, see Antidetect Browsers for Media Buyers 2026: Real Differences.

What is Undetectable, and who makes it?

An antidetect browser for Windows and macOS operated by MOBICO SERVICES LTD from Nicosia, Cyprus; its terms of service are governed by the law of Texas. There's no Linux version, no mobile app and no cloud phone.

Its idea is the split between local and cloud profiles, each with its own fingerprint, proxy and cookies. Local profiles live on your disk and are unlimited on every paid plan. Cloud profiles sync through Undetectable's servers, so a team can share them, and each plan caps their number. You can import local profiles to the cloud and export them back.

How does Undetectable build fingerprints?

From "configurations." In the company's words: "A configuration is a set of data collected from real browsers and devices. If you select a specific configuration when creating a browser profile, all of your system's fingerprints will be replaced with fingerprints from that configuration." Each plan includes a set number of configurations, 10 on Free, 25 on Base, 50 on Professional and 100 on Custom, and extra ones cost $1 each.

Configurations can be Windows, macOS, Android or iPhone devices. The mobile ones run in the desktop browser; in July 2026 Undetectable added Android network emulation to them.

What security researchers found. In March 2025, Antoine Vastel of the bot detection company Castle published an analysis of how to detect Undetectable. For profiles posing as Safari or Firefox, the browser changed values through injected JavaScript, and Castle showed those lies "can be easily detected from JavaScript since it has observable side effects." For Chromium profiles the values were changed inside the browser itself, but the injected script still left traces, functions with names like iframeCheck, that a site could find. That analysis is of a 2025 build, and the company has shipped many versions since. The lesson stands: prefer Chromium configurations, remember that even those weren't invisible in Castle's test, and don't assume a profile that claims to be Safari on Windows will pass a careful check.

How fast does Undetectable follow Chrome?

About a week. The changelog dates each Chromium update. Here's 2026 against Chrome's stable releases:

• 150. Chrome stable: June 30. Undetectable: July 7. Days behind Chrome: 7.
• 151. Chrome stable: July 28. Undetectable: August 4. Days behind Chrome: 7.
• 152. Chrome stable: August 25. Undetectable: September 1. Days behind Chrome: 7.
• 153. Chrome stable: September 8. Undetectable: September 15. Days behind Chrome: 7.
• 154. Chrome stable: September 22. Undetectable: skipped. Days behind Chrome: .
• 155. Chrome stable: October 6. Undetectable: October 13. Days behind Chrome: 7.

Since Chrome moved to a 2-week cycle, Undetectable has skipped a version. It went from 153 straight to 155 in version 2.52.0 on October 13. On October 22, 2 days after Chrome 156, it was on 155, like most of the market. The docs also mention an older second engine, WebEngine, that the company plans "to abandon in the future"; the Local API and extensions work only with Chromium profiles.

Automation: API, synchronizer and MCP

The Local API starts on Base. It lets you list, create, launch, update and close profiles, manage proxies and, since June 2026, sync profiles through the API. Puppeteer, Playwright and Selenium connect to running profiles. The free plan has no API.

There's no visual scenario builder, but 3 tools cover routine work. The synchronizer, on any paid plan, repeats the main window's typing, tabs, scrolling and extension actions in other profiles. The Cookies bot warms up profiles. And Undetectable publishes an open-source MCP server under the MIT license, so AI clients like Claude, Codex, Gemini or Cursor can drive profiles through text tasks.

Team work: users, sessions and logs

Teams start on Professional. Base has 1 user and you can't add more: the pricing page says users are "available from Professional." Professional includes 2 users and sells more at $20 each, Custom includes 5 and sells more at $15 each, up to 100. Note that the docs' plans overview, last updated in July 2026, says you can add users on Base; the pricing page says you can't, and the pricing page is what you buy.

Sessions limit how many copies of the app run at once. By default they equal the number of users, and the same user can't run Undetectable on several devices at the same time.

The cloud panel handles access. Roles and groups, "more than 33 access parameters," active sessions and action logs show who did what.

In money: 3 people need Professional, $99 a month plus $20 for the third user, so $119. The same setup costs $46 at AdsPower, $109 at Dolphin and $40 at Multilogin's Business plan. Undetectable is built for one person with many profiles, not for teams.

Signing up, the free plan and payment

The free plan is cloud-only. It allows up to 5 cloud profiles at a time, 50 profile creations a month, 1 session and 10 configurations; you can buy room for more, $10 per 10 profiles, up to 45. There are no local profiles and no API on Free. Sign up through our link.

Mind what happens if you stop paying. Per the FAQ, when you drop back to Free, your local profiles are suspended until you pay again, and cloud profiles are frozen for 6 months.

Payment is by card, e-wallet or crypto. Undetectable doesn't take PayPal. Paying yearly takes 30% off.

If you want to refer people yourself, Undetectable's affiliate program pays 10% of every referred user's purchases for life, with payouts from $50 within 2 business days.

Undetectable vs other antidetect browsers

How it compares by what you need, on monthly billing, October 22, 2026:

• Undetectable. 1,000 profiles on 1 computer: $49 (Base, local). 100 cloud profiles: $99 (Professional). 3 people: $119. Chromium kernel on October 22: 155.
• AdsPower. 1,000 profiles on 1 computer: $197 (Business). 100 cloud profiles: $36. 3 people: $46 (100 profiles). Chromium kernel on October 22: 155.
• Dolphin{anty}. 1,000 profiles on 1 computer: $299 (Enterprise). 100 cloud profiles: $89. 3 people: $109 (100 profiles). Chromium kernel on October 22: 155.
• MoreLogin. 1,000 profiles on 1 computer: $160 (Pro 1,000). 100 cloud profiles: $35. 3 people: $40 (100 profiles). Chromium kernel on October 22: 148 (last published).
• Kameleo. 1,000 profiles on 1 computer: 59 EUR (local unlimited, 10 at once). 100 cloud profiles: 59 EUR. 3 people: 59 EUR (seats unlimited). Chromium kernel on October 22: Chroma 156.
• Octo Browser. 1,000 profiles on 1 computer: 329 EUR (Advanced, 1,200). 100 cloud profiles: 79 EUR. 3 people: 169 EUR. Chromium kernel on October 22: Octium 156.

Undetectable wins when the profile count is the problem. Among the established antidetects, none gives you 1,000 profiles for $49; Kameleo comes closest with unlimited local profiles, but it caps how many browsers run at once. The cost of that deal: your profiles live on your machine, so backups and moving between computers are on you, and teams pay more than at AdsPower, Dolphin or Multilogin.

Undetectable vs AdsPower: for 100 profiles shared with a team, AdsPower is cheaper and has no-code RPA; for many profiles on one computer, Undetectable is cheaper by a wide margin. Read our AdsPower review for the team side.
