Why running multiple stores is risky
E-commerce marketplaces use sophisticated detection systems to enforce their one-account-per-seller policies. They collect browser fingerprints, track device identifiers, monitor IP addresses, and analyze behavioral patterns. If the platform determines that two seller accounts belong to the same person, both can be suspended — along with any pending payouts.
Donut Browser runs each store in a fully isolated profile with a unique browser fingerprint covering over 50 parameters. Each profile has its own cookies, local storage, and cache. Assign a dedicated proxy to each profile to match the store's target region. The profiles have no shared data — the marketplace has no way to connect them.
Your store credentials and browsing data stay on your machine. The Donut Browser app is open source with zero telemetry, so there is no risk of your marketplace session data being sent to third parties. You can inspect the app source code on GitHub to verify this.
Key Features
Isolated Seller Profiles
Each store runs in a fully independent profile with its own cookies, local storage, cache, and browser fingerprint. Marketplace session data from one store never touches another. If one store is reviewed or suspended, the others are completely unaffected.
Unique Fingerprints Per Store
Each profile generates a unique fingerprint covering Canvas, WebGL, AudioContext, screen dimensions, fonts, User-Agent, and dozens more. The fingerprints are internally consistent and match real device configurations, so the marketplace sees a normal seller — not a tool.
Regional Proxy Assignment
Assign a proxy from the store's target market region to each profile. The marketplace sees traffic from the expected location every session. Supports HTTP, HTTPS, SOCKS4, and SOCKS5 proxies with authentication.
Team Access Control
Share specific store profiles with virtual assistants or team members via the Team plan. VAs access only the stores assigned to them, without seeing your other stores. Profile locking prevents session conflicts when multiple people work on the same account.
Cookie Import & Session Transfer
Import cookies to migrate existing store sessions from other browsers or tools without logging in again. Avoid triggering marketplace security checks that fire when a seller account is accessed from a new device.
Operational Isolation for Every Major Marketplace
Run each store in its own isolated environment with unique fingerprints and dedicated proxies. If one store encounters issues, your other stores continue operating without disruption — protecting your revenue and business continuity.
Amazon
Isolated Seller Central sessions with unique fingerprints. An issue with one account never affects the others.
eBay
Separate seller accounts with independent feedback scores and listing histories across niches or regions.
Etsy
