How this differs

A platform deciding whether two accounts belong to one person has three independent channels, and one is often enough. Storage, the device, the network.

A quieter fourth thing costs more accounts than you would expect: agreement. A macOS graphics string next to an x86 architecture hint describes a machine nobody has ever built.

• Storage

  Cookies, localStorage, IndexedDB, service workers and cache. Cleared by incognito, untouched by a VPN.

• Device readings

  Platform, screen, cores, memory, GPU, fonts, timezone, languages, canvas, WebGL and audio. One set per machine.

• Exit IP

  The address the site sees, plus the country, city and provider read from it.

Incognito gives the session a temporary cookie jar and forgets it when the last window closes. It does that job well and was never meant to do more.

Everything outside that job belongs to your machine, so two incognito windows read as one computer. It forgets on purpose, so tomorrow's account is signed in again tomorrow.

• What incognito changes

  A temporary cookie jar, and no history entry once the window closes.

• What it leaves alone

  Every device reading and the exit IP.

• What a profile does instead

  Its own data directory on disk, kept between launches, with its own device and proxy.

• Where incognito is still right

  One throwaway login, one keystroke away, gone when you close it.

A VPN moves traffic through another exit and is honest about being a network tool. Thirty accounts behind one exit share one IP, and they still share one browser.

ARMANOS does not hide your address either: you bring the proxy yourself.

Besides the address, a site can ask the browser for the position itself, and that needs your answer. Incognito, a second browser profile and a VPN hand over the machine's own position after "Allow", and it need not match the exit country.

A new ARMANOS profile hands over a point a few kilometres from where a directory puts its exit, and measures that place through the same proxy. In ARMANOS Browser on a Mac the point goes out, for now, only with "Share without asking" ticked.

A virtual machine is a second computer in software, and the wall around it is thicker than ours. If your work needs that wall, use one.

The price is paid in resources and minutes: a system to keep patched, memory reserved, tens of gigabytes of disk and a boot before the first click. The numbers below were taken on a deliberately weak machine, so you see the worst case rather than the best.

An extension is JavaScript in the page, so even at the earliest injection point it corrects values the browser already produced. A getter can name one graphics card while the pixels are drawn by the real one.

ARMANOS assembles the device in C++ before the first script runs. Nine surfaces are closed that way, and each is proven by a marker found in the source tree at build time.

• WebGL pixel readback

  A page that reads pixels back gets them with this profile's noise.

• Timezone, locale and calendar

  The clock, the calendar and the way numbers and dates are written are the profile's own.

• Font list

  Fonts answer for the profile, not for the machine underneath.

• Input and output devices

  The count of cameras, microphones and speakers is the profile's.

• Speech voices

  Voices match the language the profile claims to speak.

• Network readings

  Connection speed, round trip time and type are the ones the profile names.

• Heap limit

  Clamped to the memory the profile declares, in Chromium's own steps.

• WebGPU readback

  An image captured through WebGPU comes back with the same noise as through WebGL.

• Three mobile connection fields

  Given to phone profiles only: desktop Chrome does not carry them.

A second profile in an ordinary browser gets its own cookie jar, history and extensions, and it costs nothing. What it shares is everything else: one font list, one graphics card, one screen, one exit IP.

They also have no notion of a team. An ARMANOS profile carries its own device, its own proxy, a group and tags, and on a paid plan the whole team sees it, with no way for two people to open it at once.

A second laptop on a different line is a different device on a different network, with nothing substituted anywhere. It stops working as a plan at about the third device: fifty accounts means fifty machines to buy and keep.

Our unit is a profile and the price list is short. Devices are counted separately, and a session travels in an encrypted file or a folder you already sync.

• 50 profiles

  The tier that covers fifty accounts, about 28 cents each.

  $14 / month

• One extra profile

  Added one at a time above your tier.

  $2 / month

• One team seat

  A colleague with a role and their own login.

  $3 / month

• A year up front

  A quarter takes 10 percent off.

  20% off

• Free plan

  Forever, no card, on the same engine the paid plans run.

  2 profiles

Read the dashes as scope, not as insults. A tool is not worse for declining a job it never advertised.

Three cells here belong to the other side. You can check any number in the ARMANOS column: it is either measured on the finished app or written in a file named below.

We would rather you picked the cheap tool when it is right. Every line below is advice we would give in person.

The rule is short: use ARMANOS when you need many lasting accounts that must not be linked to each other.

• Incognito, for one throwaway login

  One keystroke, nothing installed, nothing left behind.

• A VPN, for the whole machine

  It covers apps that are not browsers. A proxy inside a profile does nothing for your mail client.

• A virtual machine, for depth

  Its own kernel and its own operating system, where our profiles share yours.

• An extension, for a browser you already use

  Nothing new to install and no cost, if one account is all you have.

• A second device, for one account worth more than the rest

  No substitution anywhere. If losing it would cost more than a laptop, give it a laptop.

The six lines below are printed next to our price list, and they describe capabilities rather than outcomes. What we sell is isolation and a device that stays the same.

We publish no numbers about other products, because we cannot measure them honestly. Every number here comes from our own code or our own measurement.

• Isolated profiles

  Separate cookies, storage and cache per profile.

• Fingerprint parameters per profile

  A stable set of user agent, language, resolution and hardware hints.

• Proxy per profile

  An HTTP or SOCKS5 proxy per profile, so its traffic follows its own route.

• Link and tracker cleaning

  Tracking parameters are stripped on every navigation and known trackers are blocked.

• Pay for what you add

  Start free, then add extra profiles one at a time.

• Own engine, included

  The substitution happens inside the engine, on every plan including the free one.
