Run unlimited accounts in their own browsers.
The free, open-source multi-profile browser. Each profile looks like a separate device, so platforms can't link two accounts to one machine.
Why most multi-account setups get caught
Logging into the same site twice gives you away. Platforms read your device (screen, fonts, GPU, timezone) and tie both accounts to one machine. Clearing cookies and switching to incognito does nothing.
Donut Browser is a multi-profile browser that runs each account in its own isolated browser. Every profile looks like a separate device, so platforms can't link them. Great for running multiple ad accounts, managing multiple stores, or running multiple crypto wallets.
It's free, local, and open source under AGPL-3.0. No profile limits, no telemetry, no subscription; the only ceiling is your hardware. A real MultiLogin, AdsPower, and GoLogin alternative.
One machine, four identities that never link
Click through the profiles. Each one shows a different device fingerprint, canvas hash, timezone, locale, proxy exit and browser to a tracker. Profile A is your real browser, read live in this tab.
Profile A reads the actual fingerprint of the browser you are using right now, so you can see it is genuinely yours. The other profiles carry completely different, internally consistent identities. To any site, they look like four separate people on four separate machines.
Key Features
Unlimited browser profiles, no artificial caps.
Create as many profiles as your machine can handle. Donut never meters profiles or charges per profile, even on the free plan.
Every profile looks like a separate device.
A unique device identity per profile means platforms can't link two accounts to one machine. Pass account-linking checks without spinning up disposable VMs.
Organize profiles your way.
Tag, group, color-code, and search profiles instantly. Keep work, personal, and client accounts cleanly separated inside one dashboard.
Each account has its own location.
Bind any HTTP, HTTPS, SOCKS4, or SOCKS5 proxy to a profile. Geographic identity sticks across sessions, so your IP stays consistent on every launch.
Import from any browser.
Move your existing Chrome, Edge, or Brave sessions into Donut in a click. No re-logins, no new-device security checks.
Sync profiles across machines.
Optional end-to-end encrypted sync keeps profiles available on every device. Your sync password never leaves your machine. Pro plan.
How It Works
Create a Profile
Click "New Profile" to create a Wayfern (Chromium-based) profile. Optionally bind a proxy and add a tag or group. Setup takes seconds.
Automatic Device Identity
Donut generates a unique, realistic device identity for the profile, internally consistent down to fonts and screen size, so the profile looks like a real machine rather than a bot.
Launch and Work
Open profiles from the dashboard. Each runs in its own window with its own session, side by side, with cookies and login state persisting between launches.
