This is what every site sees

This is what this page has read in your browser. Nothing is sent anywhere: it is all computed on your side. Below — what detectors see on a Vflin profile.

  • Open this page in another tab — the number will be the same.

02 · What it is strong at

Six things Vflin stands on

  • your machine's address on the page 0

    WebRTC and QUIC go through the profile's proxy or not at all — never around it.

  • Inside the profile is Chromium itself: TLS, HTTP/2 and QUIC are Chrome's.

  • The graphics card, screen, fonts and system are chosen together, as on a real computer.

    Check it yourself on pixelscan and fingerprint.com.

  • A scenario on a whole folder and on a schedule, the cookie warm-up robot, the window synchronizer.

  • Puppeteer and Playwright connect to any profile; an MCP server is bundled.

  • A profile is encrypted on your computer — the cloud holds only ciphertext.

03 · The app

Profiles, proxies and wallets in one window

Frames of the running app on sample data — and each says what is strong in it.

Each profile's row shows the core version it lives on and its work status. A launch is one button, and the chosen profiles of a folder launch with one action.

The Vflin profile list: the Ads folder of seven profiles; each has a “Start” button, its core version, a status, tags and a note.
The profile list · the Ads folder · sample data

The core version is in every row: after a move to a new Chrome you see which profile has moved already. And before the move the app shows what will change — only the claimed version and what follows from it, as in a real Chrome update.

05 · Network

UDP and TCP — through the profile's one exit

WebRTC usually gives away the machine's real address around the proxy. Here datagrams go through our own relay and the same exit as the pages. Pick a situation and make a call — you can see where every datagram goes.

06 · What for

Work where accounts cannot share one browser

Every account gets a profile of its own: its own device, its own proxy, its own cookies. To a site they are different people on different computers.

Traffic arbitrage

Facebook, Google and TikTok ad accounts — each in a profile of its own, with its own proxy.

Crypto and Web3

Every profile has a Rabby wallet of its own.

E-commerce

Stores on marketplaces and on their own sites — each with its own device and address.

SMM

Social accounts in folders, a profile each.

Development and testing

A profile with the device and the country you need — and the same profile tomorrow.

The names and marks belong to their owners. Vflin is not affiliated with them.

07 · Automation

A scenario that does not break on live sites

The pointer drives a real mouse: it comes up to the button, stops, presses and lets go. Text is typed key by key, the page scrolls with the wheel. So menus open, fields see every key, and buttons fire. Run the scenario here — on one profile or on a whole folder.

08 · For developers

Connect Vflin to your tools

The local API answers on your computer over HTTP. It offers the same actions as the window: create a profile, launch it, hand it a scenario and read the result. The same methods are in the command line, and for AI agents there is MCP.

Developers: API, CLI and MCP →

  1. HTTP$ curl -X POST -H "Authorization: Bearer $TOKEN" http://127.0.0.1:$PORT/v1/profiles/$ID/start
  2. CLI$ vflin profile start $ID
  3. MCP› vflin_profile_start { "id": "$ID" }

An example task

In the morning, on a schedule, open the twenty profiles of a folder, run one check in each and put the result into a table — with a scenario from the app or with five lines of your own code.

Documentation: Local API, CLI and MCP.

09 · The cloud

Carry on working on another computer

A profile is encrypted on your computer and goes to the cloud sealed. Someone with access to our server sees how many profiles you have and how large they are — but not their contents, cookies, fingerprint, proxy or password. This was checked by querying the database, not retold.

What the server sees →

  • The password does not leave, even at sign-in
  • The cloud can run on your own server
  1. Your computerThe profile is encrypted here
  2. Another computerThe same profile, your key

Questions before installing

What core does Vflin run on, and how is it updated?

On its own Chromium build, and the app shows the version. The core is updated separately from the app — we carry our changes over to the fresh stable Chrome about once a month.

Which proxies are supported?

HTTP, HTTPS, SOCKS4 and SOCKS5, with a login and password. The password goes into encrypted storage and is never handed back — the registry only shows that it is set. WebRTC goes through the profile's exit; when the proxy cannot do UDP, the core answers with the exit's address itself.

How many profiles can be open at once, and what does the computer need?

Every open profile is a separate browser window, so how many you can have is limited by the computer's memory; we give no number of our own until we have measured it on different machines. It needs Windows 10 or 11, x64.

Can profiles and cookies be moved from another program?

Yes: an export file or a list of profiles as text — Vflin creates profiles with their settings (user agent, screen, language, time zone). Cookies are loaded from a file into an open profile — merged or replacing the whole set.

How do I work as a team and share profiles?

A profile is handed to a team member together with the key that opens it, and access is revoked by changing the key. Roles, permissions and the action log live in the cloud part of the account.

Can you see my cookies, passwords and wallets?

No. A profile's contents are encrypted on your computer, only ciphertext goes to the cloud, and the server has no keys to it.

Which wallets are supported, and where are the keys?

Rabby, for now. The key goes once to the program on your computer and is sealed into the profile; the API never hands it back.

Is there an API, and can Puppeteer, Playwright or an AI agent be connected?

There is a local HTTP API, a command line and MCP for agents. A profile can be opened with a CDP port — then Puppeteer or Playwright connect to it; by default the channel is closed and open only to the Vflin program.

What happens to my profiles if I stop paying?

The account returns to the free plan: 5 profiles stay working — you choose which — and the rest become read-only: they can be exported to a file, and a renewal brings everything back at once. If the plan is not renewed, the cloud copies of the extra profiles are deleted in time — a letter comes before that, and the copies on the computer stay.

How do I pay, and are there refunds?

Plans are monthly, paid in crypto, no card. A refund is made within 14 days of the payment, for the days still ahead, to the address you name. Prices are on the pricing page, the refund terms on the refunds page.

Why does Windows complain about the installer?

The installer is not signed with a certificate yet, so Windows shows a SmartScreen warning. The download page gives the file's size and checksum — compare them before installing.

Which operating systems are supported?

A version for Windows 10 and 11, x64, is available now. Versions for macOS and Linux are not released yet.
