Our position, stated up front: we are Geonode and we sell proxies, which makes antidetect browsers adjacent to our business rather than competing with it. We have an incentive to be enthusiastic about this category, so the disclaimer belongs here — an antidetect browser without matching proxies is close to pointless, and buying one before you have worked out whether you need it is a common and avoidable waste. A tool that gives each profile a distinct browser fingerprint while every profile arrives from the same address has solved the smaller half of the problem and left the obvious half untouched. Conversely, proxies without fingerprint management leave you with varied addresses and identical browsers. They are complements, and if you are only going to get one, work out which half of your problem is larger before spending anything.
Also, on the name: no product in this category is undetectable, and we will spend a section on why.
First: Undetectable.io Is Not Undetectable.ai
Worth ten seconds because the confusion is widespread and the two products have nothing in common.
undetectable.io is the antidetect browser reviewed here — profile isolation, fingerprint management, proxy integration, aimed at people running multiple browser sessions that need to look like separate devices.
undetectable.ai is an AI-text rewriting service aimed at making machine-generated writing read as human. Different company, different problem, different customer.
Both domains resolve and both are live — we checked in September 2026 — so you can end up on the wrong one without any sign that you have. If you arrived here after searching for one of them, check which product you actually want before reading further.
What It Actually Does
The core proposition is standard for the category, and the implementation is more complete than most.
Profile isolation with distinct fingerprints. The vendor describes it as giving each profile "its own set of parameters", spanning "device, browser, geolocation, language, time zone, fonts, Canvas, WebGL, Cookies, User-Agent". Each profile is meant to present as a separate machine.
Bulk profile creation. Profiles can be generated in quantity from files containing user-agent strings, cookies and proxy details — the marketing claim is creating "hundreds of unique profiles in a few clicks". For anyone managing profiles at scale this is the difference between a usable tool and a data-entry job.
Integrated proxy management. A dedicated interface to add proxies individually or in bulk, check their status, and assign them to profiles. The documentation has a section specifically on connecting, checking, importing and configuring proxies. This matters more than it sounds: assigning the wrong proxy to the wrong profile is the most common way people undermine their own setup, and tooling that makes the mapping visible prevents a whole class of mistakes.
Automation via API. The API allows you to "fetch the list of profiles, create, launch, update and close them", with integration for Puppeteer, Playwright and Selenium. This is the feature that separates tools you can build a pipeline around from tools you have to click through, and it is present here.
MCP integration for AI agents. A more recent addition: connection to agent tools including Claude, Codex, Gemini and Cursor via the Model Context Protocol, so that an agent "creates profiles, sets proxies, and drives real sessions" from a text description. Whether this is genuinely useful or a checkbox depends entirely on your workflow, but it is unusual in this category and worth knowing about if you already work with agents.
Supporting tools. Bulk extension installation across profiles, and a cookie format converter.
Platform support: Mac and Windows. No Linux client, which will rule it out for some people immediately.
Pricing, Verified
From the vendor's own pricing page, checked September 2026. Verify before purchase — this category changes prices often.
| Plan | Monthly | Annual | Cloud profiles | Users | Browser configs |
|---|
| Free | $0 | — | 5 at a time, 50 creations/month | 1 | 10 |
| Base | $34 | $412 | 50 | 1 | 25 |
| Professional | $69 | $832 | 100 | 2, +$20/user | 50 |
| Custom | $139 | $1,672 | up to 10,200, +$100 per 1,000 | up to 100, +$15/user | 100 |
Three observations.
The free tier is genuinely usable for evaluation. Five simultaneous cloud profiles with a monthly ceiling of 50 creations is enough to test whether the tool fits your workflow before paying. That is more than most competitors offer and it removes the main reason to guess.
The annual pricing is not much of a discount. $412 against $408 for twelve monthly payments at the Base tier is, within rounding, no discount at all. Same at Professional: $832 versus $828. This is unusual — most tools in this space offer 20–40% for annual commitment — and the practical implication is that you should pay monthly. There is no financial reason to lock in, so do not.
Per-user pricing adds up. $20 per additional user on Professional and $15 on Custom. A five-person team on Professional is $69 plus $60, so $129/month — closer to the Custom tier than the headline suggests. Cost your actual team, not the base plan.
Local Versus Cloud Profiles and Why It Matters
The pricing table counts cloud profiles, and the distinction is the most consequential thing in this review.
Cloud profiles are stored on the vendor's infrastructure. They synchronise across machines, they are what team collaboration is built on, and they are what your plan limits count.
Local profiles live on your own machine. The documentation refers to a configurable "profile storage location", and local storage is generally not counted against cloud quotas.
Why this matters in both directions:
In favour of cloud: a profile that exists on one laptop is a profile that dies with that laptop. If several people need to work the same profiles, or if you need continuity across machines, cloud storage is the feature you are paying for and it is worth it.
Against cloud: profile data includes cookies and session state, which is to say credentials in a usable form. Storing that on a third party's infrastructure is a trust decision, not just a convenience one. For anything sensitive, understand where the data sits and what the vendor's security posture is before defaulting to the cloud because it is what the plan counts.
The practical approach for most people is a mix — cloud for profiles that need sharing or continuity, local for everything else — which also keeps you on a cheaper tier. Whether that is worth the added mental overhead depends on how many profiles you run.
Automation and the API
For anyone building a pipeline rather than clicking through a UI, this section decides the purchase.
The API covers profile lifecycle — list, create, launch, update, close — which is the necessary set. Combined with Puppeteer, Playwright or Selenium integration, that means you can drive profiles programmatically rather than manually, which is the difference between a tool that scales and one that occupies a person.
The pattern that works: your automation creates a profile with the fingerprint parameters you want, assigns a proxy from your pool, launches it, hands control to Playwright or Puppeteer for the actual work, then closes it. The antidetect browser handles identity; your automation framework handles behaviour.
Two things to plan for regardless of vendor.
Bandwidth. A full browser fetches everything — images, fonts, trackers, video. On metered residential traffic this is the dominant cost of the whole operation, frequently by an order of magnitude over the software subscription. Blocking unnecessary resource types at the browser level is the single highest-value optimisation available, and it is easy to forget until the invoice arrives.
Proxy-to-profile mapping stability. A profile that used a German address yesterday and a Brazilian one today is a profile with an incoherent history. Whatever you build, make the mapping durable and explicit. This is where the built-in proxy manager earns its place — but only if you use it consistently rather than reassigning ad hoc.
What the Name Promises and What Fingerprinting Actually Is
The honest section, and it applies to every product in this category rather than this one specifically.
Browser fingerprinting works by combining many individually unremarkable signals — screen dimensions, installed fonts, canvas and WebGL rendering characteristics, audio processing behaviour, time zone, language, hardware concurrency, and dozens more — into a combination that is frequently unique. Antidetect browsers modify those signals so that each profile presents a different combination.
The limits are structural, and worth understanding before you rely on the tool:
Consistency is harder than variety. Generating a different fingerprint is easy. Generating one that is internally coherent is not. A profile claiming to be macOS while exposing Windows font metrics, or reporting a Brazilian time zone while resolving DNS through a European resolver, is more identifiable than a profile that did nothing at all — because ordinary users do not produce contradictions.
The address is part of the fingerprint. This is where our commercial interest lies and we will state it plainly: fingerprint management without matching proxies fails at the first check. Fifty profiles that look like fifty devices, all arriving from one address, is a pattern that is easier to spot than fifty identical browsers on fifty addresses. The two halves have to move together.
Behaviour is a signal too. Timing, mouse movement, scroll patterns, how quickly forms are filled. No fingerprint tool addresses this, and at scale it is often what gives an operation away.
It is an arms race with an asymmetry. Detection improves continuously and the detecting side has more data than you do. A configuration that works today is not a permanent asset. Any plan that assumes otherwise will need revisiting.
So: treat "undetectable" as a product name rather than a specification. The realistic claim for this category — and it is a genuinely useful one — is that good fingerprint management makes profiles harder to correlate with each other. Harder is not impossible, and the honest vendors in this space say so. We covered the general landscape in our overview of antidetect browsers.
How It Compares to the Alternatives
All figures from the vendors' own pricing pages, checked September 2026.
| Tool | Free tier | Entry paid | Mid tier | Additional users |
|---|
| Undetectable.io | 5 profiles, 50/month | $34/mo (50 profiles) | $69/mo (100 profiles) | +$20 |
| Dolphin Anty | 5 profiles | $10/mo (up to 60) | $89/mo (100 profiles) | +$10 |
| GoLogin | 3 profiles | $24/mo annual, $49 monthly (100 profiles) | $49/mo annual (300 profiles) | Single user on listed plans |
Reading the table:
Dolphin Anty's Starter tier at $10/month for up to 60 profiles is the cheapest serious entry point, and it is not close. If cost is your constraint and a single user is enough, that is where to look first. Its jump to $89/month for the Base tier is steep, though, so check which side of that step your requirements fall on. Note also that Dolphin Anty offers 20% off for 6–11 month commitments and 40% for twelve, which is a real discount rather than a nominal one.
GoLogin is the profile-count leader per pound. 300 profiles at $49/month on annual billing, 1,000 at $99. If you need many profiles and one seat, the arithmetic favours it. It also offers a 7-day trial of all advanced features plus a free tier of 3 profiles.
Undetectable.io sits in the middle on price and ahead on evaluation. Its free tier is the most usable of the three for genuinely testing a workflow, its proxy management is well integrated, and the API plus MCP support is the most developer-oriented of the group. What it does not offer is a meaningful annual discount, which is a point in favour of just paying monthly and staying flexible.
We have reviewed two of these in detail: Dolphin Anty and GoLogin, plus Hidemium.
Who It Suits and Who Should Skip It
Good fit if: you are automating multi-profile work and need an API rather than a UI; you want to evaluate properly before paying, and the free tier lets you; you need integrated proxy management because your setup involves many address-to-profile mappings; you already work with AI agents and the MCP integration fits your workflow; you are on Mac or Windows.
Poor fit if:
You are on Linux. Mac and Windows only. This ends the discussion for a meaningful share of technical users.
You need many profiles cheaply. The per-profile economics favour others. 100 profiles at $69/month here versus 300 at $49/month elsewhere is a large gap if profile count is your binding constraint.
You wanted an annual discount. There effectively is not one. Pay monthly.
You have not established that you need fingerprint management at all. This is the big one. If you are scraping public pages and getting rate-limited, your problem is request distribution and an antidetect browser will not touch it — you need proxies and better pacing. If you are managing a handful of accounts you legitimately own, most platforms provide official multi-account tooling that is free and does not risk the accounts. Antidetect browsers earn their place when you have many distinct browser identities that must not correlate, and that is a narrower requirement than the marketing in this category implies.
You expect it to solve detection on its own. Fingerprint management is one layer. Address, behaviour and account history are the others, and a tool that perfects one while you ignore three has not moved you very far.
People Also Ask
Is Undetectable.io actually undetectable?
No, and no product in this category is. It manages browser fingerprint parameters so profiles are harder to correlate with each other, which is genuinely useful. Detection also uses network address, behavioural patterns and account history, none of which a fingerprint tool addresses. Treat the name as branding.
Is there a free version of Undetectable.io?
Yes — five cloud profiles running at a time with a limit of 50 profile creations per month, one user, ten browser configurations. It is the most usable free tier among the major antidetect browsers and enough to establish whether the tool fits your workflow.
How much does Undetectable.io cost?
$34/month for Base (50 cloud profiles), $69/month for Professional (100 profiles, 2 users), $139/month for Custom (up to 10,200 profiles, up to 100 users). Annual billing is $412, $832 and $1,672 respectively, which is essentially no discount on paying monthly.
Does Undetectable.io include proxies?
No. It provides proxy management — adding, checking and assigning them to profiles — but you supply the proxies. This is normal for the category, and it means the software subscription is only part of your cost. Residential bandwidth typically dominates the total.
Undetectable.io or Dolphin Anty?
Dolphin Anty if price per profile is your constraint: $10/month for up to 60 profiles is the cheapest serious entry, with real annual discounts. Undetectable.io if you want a better free tier for evaluation, tighter proxy integration, or the API and MCP support for automation.
Does it work on Linux?
No. Mac and Windows only as of September 2026. If you need Linux, this is a hard stop rather than an inconvenience.
Can I automate Undetectable.io?
Yes. The API covers listing, creating, launching, updating and closing profiles, with integration for Puppeteer, Playwright and Selenium. There is also MCP support for driving sessions from AI agent tools.
Do I need proxies with an antidetect browser?
Effectively, yes. Multiple profiles arriving from a single address defeat the purpose — you have made the browsers different while leaving the most visible signal identical. The two are complementary and neither works well alone.
Wrapping Up
Undetectable.io is a competent tool in a crowded category, and its distinguishing features are practical rather than dramatic: a free tier that lets you evaluate properly, proxy management that is integrated rather than bolted on, and an API that makes automation straightforward. The absence of a real annual discount is unusual and works in your favour — pay monthly, stay flexible.
If profile count per pound is what you are optimising, others are cheaper. If you are on Linux, it is not available to you. If you have not yet established that fingerprint management is your actual problem, that is the question to answer before comparing any of them.
And the name deserves a final word. Nothing in this category is undetectable, the vendors that are candid about this are the more trustworthy ones, and the realistic goal — making separate profiles hard to correlate — is worth paying for on its own terms. It just requires the other half of the setup to be in place, which is where our own product comes in and where we would rather you understood the whole picture before buying either.
