Ant0 Download

Getting started

Install Ant0, get the browser engine, add a proxy and open your first profile. About ten minutes, most of it the engine download.

What Ant0 is

Ant0 runs many separate browsers from one list. Each profile is a separate browser with its own identity, cookies and connection. Websites see each profile as a different visitor on a different computer, so your accounts stay apart. You start a profile to open its window, do your work inside it, and stop it when you are done.

Two things run on your computer: the Ant0 app (the window with the list) and, behind it, a small background service that keeps the profiles and launches browsers. The browsers themselves are Ant0 Browser, a Chromium build the app downloads once and keeps up to date.

1. Install

Download the installer for your system from the download page.

  • Windows 10 or 11 (64-bit). Run Ant0_<version>_x64-setup.exe. It installs for the current user under %LOCALAPPDATA%\Programs\Ant0 and needs no administrator rights. Windows shows a SmartScreen notice because the installer is not yet code-signed; choose More info → Run anyway after checking the file’s hash.

  • Debian 12, Ubuntu 22.04 or newer (64-bit). Install the package:

    sudo apt install ./Ant0_<version>_amd64.deb

    Then start Ant0 from your applications menu, or run ant0-desktop.

2. First run

The app opens on a three-step setup. The steps can be done in any order and the sidebar stays usable throughout.

  1. Install the browser engine. About 510 MB, downloaded from releases.ant0.link and checked against a signing key before it is used. Nothing starts without it.
  2. Add a proxy (optional but recommended). Paste the line your provider gave you, for example user:pass@host:port or http://user:pass@host:port. Ant0 checks that it works and shows the country it exits from. Without a proxy, every profile shares your computer’s internet address, so websites can link them to each other.
  3. Create your first profile. Give it a name. Everything else has a sensible default.

Leave Add a sample profile on if you want a filled-in example in the list; it is safe to delete.

3. Start a profile

Press Start on a row. A browser window opens for that profile after a few seconds; the row’s status turns to Running with a green dot. Sign in to the account that belongs to this profile and work as usual. When you are done, press Stop on the row or simply close the browser window. Cookies and logins are kept with the profile for the next start.

You can have several profiles running at once. Each has its own window and its own connection.

4. Keep the list in order

  • Folders (left column) hold profiles by client, shop or task. A profile is in exactly one folder.
  • Tags cross-cut folders (eu, vip, warmup). Search by tag with the scope button next to the search field.
  • Notes show in the table and can be edited inline.
  • Pin keeps profiles at the top of the Pinned view.
  • The ⋮ menu on each row holds Start, Edit, Change proxy, Cookies, Duplicate, Move to folder, Pin and Delete. Right-click does the same.

Deleted profiles go to Trash and are kept for 7 days; Restore brings one back with all its data.
