The antidetect browser that keeps every profile on your own computer

What an antidetect browser does

Every website you visit can read dozens of small details about your browser: the operating system it reports, the time zone and languages, how your graphics card draws a test image, which fonts and audio stack you have, and the IP address you connect from. Put together, these details form a fingerprint that is stable enough to recognize the same browser across logins, even after cookies are cleared.

That is useful for fraud prevention, and it is a problem when you legitimately run several accounts: a social media manager with 30 client pages, an agency that runs ad accounts for different businesses, a seller with one shop per brand. In a normal browser, every one of those accounts looks like it comes from the same device.

An antidetect browser, also called a multi-account browser or browser profile manager, gives each account its own browser profile. Each profile keeps separate cookies, storage, extensions and saved logins, connects through its own proxy, and presents its own consistent set of fingerprint values. Multime does this on your own Mac or Windows computer.

How Multime works

You create a profile, choose a proxy, and click Open. Multime launches a separate Chromium-based browser window for that profile. Behind the window:

• A seed drives the profile's fingerprint values, so the profile looks the same every time you open it and no two profiles share them.
• The proxy decides the rest. Multime checks the exit IP through the proxy and sets the profile's time zone, languages and location to match it. It keeps the language list consistent with the browser's interface language, which is one of the checks fingerprint testers use.
• Masking adds small, stable noise to canvas, WebGL images, audio and element sizes, and can mask graphics card details. Where an engine version handles a check badly, Multime switches it off rather than leave a visible inconsistency.
• Your data stays local. Profiles, cookies, saved logins and 2FA keys live in a local database on your computer, with secrets encrypted. Multime has no profile cloud to breach or shut down.

You can test any profile with our free browser fingerprint test. On macOS with the Chrome 152 engine, a Multime profile tested on Pixelscan on 22 October 2026 showed "consistent", "No masking detected" and "No automated behavior detected".

Built for teams that hand work to VAs

Most teams that run many accounts also delegate. Multime's team workspace runs on the owner's computer, not on a vendor server. You create an account for each VA, choose which profile groups they can open and what they can do, and watch an owner dashboard: who is online, which profile each person has open, and an activity log of every action.

A profile can only be open by one person at a time, and VAs don't see the passwords stored in it unless you give them the "See account passwords and 2FA keys" permission. When a VA closes a profile, its cookies and browser data go back to your computer. Your own private workspace stays invisible to them.

What you can automate

Repetitive work is where teams lose hours. Multime includes a no-code automation editor with web actions, waits, loops, Excel and Google Sheets steps, email and 2FA code steps, and schedules. Flows run across many profiles at once with a thread limit you set. Developers can use the local API to open a profile and drive it with Puppeteer, Playwright or Selenium. The window synchronizer mirrors your clicks and typing from one window to others when you need to do the same thing in several profiles.

Honest limits

Multime runs on Apple Silicon Macs (macOS 13 or later) and 64-bit Windows 10 and 11. Intel Macs are not supported. The screen size a profile reports is always your real screen, and media devices, speech voices and font lists are not masked yet. There are no Android or iOS profiles. We list these limits so you can decide with the full picture, and we update them as the engine improves.

No browser can promise that an account will never be restricted. Platforms judge accounts by behavior, payment details, phone numbers and content as well as by the browser. Multime keeps accounts cleanly separated and organized; the platforms' rules still apply.
