Donut Browser

What is Donut Browser?

Donut Browser is an open source anti-detect browser designed to help you separate browser identities. Instead of sharing the same fingerprint, cookies, and settings across all sessions, it creates isolated local profiles so each profile can appear as a distinct device.

Its core purpose is to support workflows that require multiple identities and reliable automation, including web scraping/testing and multi-account management where fingerprint and session isolation matter.

Key Features

• Unlimited local profiles with unique identity per profile: Each profile has its own fingerprint, cookies, and settings so sessions are isolated from one another.
• Browser profile management via local REST API (available to all users): Programmatically manage profiles, proxies, and settings through an API.
• Proxy support (HTTP/SOCKS5) per profile: Route traffic through different proxies depending on the profile.
• VPN support (WireGuard, OpenVPN): Use VPNs to support IP isolation as part of the browsing configuration.
• Open source with zero telemetry: The site states the browser collects zero telemetry, stores data locally, and is open source.
• Automation-oriented integration options: Donut Browser’s Pro plan includes a browser manipulation API and MCP support, and supports connecting to Puppeteer, Playwright, or Selenium.
• Chromium and Firefox engines with fingerprint spoofing: You can choose a Chromium-based engine (Wayfern) or a Firefox-based engine (Camoufox) with advanced fingerprint spoofing.

How to Use Donut Browser

1. Download Donut Browser for your platform (macOS, Windows, Linux, including Apple Silicon).
2. Create multiple local profiles inside the browser, one for each identity you want to isolate.
3. Configure networking per profile by setting a proxy (HTTP/SOCKS5) and/or VPN support (WireGuard/OpenVPN) as needed.
4. For automated workflows, use the local REST API to manage profiles programmatically; for deeper automation and AI-tool integration, use the Pro features described on the site.
5. (If applicable) Set a profile as your default browser within Donut Browser so your regular browsing uses the selected identity.

Use Cases

• Multi-account management for web platforms: Run separate accounts with isolated cookies, storage, and fingerprint so switching identities doesn’t rely on log-out/into incognito alone.
• Web scraping and automation at scale: Use isolated profiles to reduce correlation across runs, while controlling proxies per profile.
• Affiliate marketing workflows: Manage multiple campaign identities with separate browser profiles and network routing.
• E-commerce operations across stores: Keep store-specific sessions isolated, including per-store proxy/IP selection.
• Privacy-oriented separation of work and personal browsing: Maintain distinct browser identities for different contexts so trackers and fingerprints aren’t shared across profiles.

FAQ

• Is Donut Browser open source? Yes. The site describes it as open source.

• Does Donut Browser sync data to the cloud? The page states it has zero telemetry and that data is stored locally. It also describes a Pro plan feature called Profile Synchronizer for Wayfern (and cloud profile backup in the pricing section), but specific details beyond that statement aren’t provided.

• What browsers are supported? The page states you can choose between a Chromium-based engine (Wayfern) and a Firefox-based engine (Camoufox).

• How do I automate profile management? The site states a local REST API is available to all users for managing profiles, proxies, and settings programmatically. It also notes that Pro unlocks additional browser manipulation capabilities and integration support.

• What networking options are available? Donut Browser supports HTTP/SOCKS5 proxies and VPN support for WireGuard and OpenVPN.

Alternatives

• Regular browsers with incognito/private mode: These provide basic session separation, but the site notes fingerprints can still be shared across tabs/sessions, so identity isolation is typically weaker.
• Headless browser frameworks alone (e.g., Puppeteer/Playwright/Selenium): Automation frameworks can run scripts, but the page positions Donut Browser as focusing on real browser engines and fingerprint spoofing rather than plain headless operation.
• General proxy/VPN rotation tools: Tools that rotate IPs help with IP isolation, but they don’t inherently provide per-profile fingerprint and cookie/storage isolation like Donut Browser’s local profiles.
• Other anti-detect/browser profile managers (category alternative): Similar products in this category focus on managing multiple browser identities; differences are typically in supported engines, automation integration depth, and how profiles are managed.
