Why scaling ad accounts is risky
Ad platforms invest heavily in detecting users who operate multiple accounts. They collect browser fingerprints — Canvas rendering, WebGL output, installed fonts, screen resolution, timezone, and hardware characteristics — and combine them with IP addresses, behavioral patterns, and billing information to link accounts. If two accounts share any of these signals, both can be flagged and banned.
Donut Browser isolates each ad account in its own profile with a unique fingerprint covering over 50 parameters. Assign a dedicated proxy to each profile so the IP matches your target region. All session data — cookies, login state, tracking pixels — persists between sessions, so your warmed-up accounts stay intact.
Unlike closed-source alternatives, the Donut Browser app is open source and does not collect telemetry. Your campaign data, account credentials, and browsing activity stay on your machine. You can verify this by reviewing the app source code on GitHub.
Key Features
Isolated Ad Accounts
Each ad account runs in a fully isolated profile with its own cookies, local storage, cache, and browser fingerprint. Platforms cannot detect that two accounts are managed from the same device. An issue with one account has zero effect on the others.
Proxy Per Profile
Assign a dedicated proxy (HTTP, HTTPS, SOCKS4, or SOCKS5) to each profile. The proxy stays consistent across sessions, so your IP does not change between logins. Match the proxy region to your target audience for geographic consistency.
Built-in Traffic Monitoring
Monitor bandwidth usage per profile and per proxy. Track how much traffic each campaign generates and identify which profiles are most active. Bandwidth data is stored locally — nothing is sent to third parties.
Profile Organization at Scale
Tag and group profiles by ad network, campaign, client, or any other criteria. Filter profiles from the dashboard, bulk-assign proxies, and manage hundreds of accounts without losing track. Notes per profile let you record campaign details.
Cookie Import & Export
Import cookies into profiles to transfer warmed-up sessions from other tools. Export cookies to back up account sessions before making changes. Migrating accounts between devices does not require logging in again.
Campaign Isolation Across Every Major Ad Platform
Run campaigns on multiple ad platforms with complete isolation between accounts. Each account operates in its own profile with a unique fingerprint and dedicated proxy. A disruption to one account never affects the rest.
Meta Ads
Run separate Business Manager accounts in isolated profiles. Each has its own fingerprint, cookies, and proxy. If one account hits a review, your other accounts are unaffected — there is no browser-level connection between them.
Google Ads
Manage multiple Google Ads accounts with independent conversion tracking, billing, and performance data. Each profile keeps its Google session completely separate from the others.
TikTok Ads
Isolate TikTok ad accounts with separate creative libraries, audience data, and campaign history. Test different strategies across accounts without risk of cross-contamination.
Native & Other Networks
Dedicated profiles for Taboola, Outbrain, MGID, Microsoft Ads, Twitter Ads, and any other ad platform. Each runs in complete isolation with its own identity.
