# Donut Browser > A powerful open-source anti-detect browser that puts you in control of your browsing experience. Donut Browser is a trustworthy alternative to closed-source anti-detect browsers. It is fully open source, collects zero telemetry, and was built as a privacy tool from the ground up. The source code is available at https://github.com/zhom/donutbrowser under the AGPL-3.0 license. Website: https://donutbrowser.com Contact: contact@donutbrowser.com ## What Is Donut Browser? Donut Browser is a desktop application that lets users create and manage unlimited isolated browser profiles, each with unique fingerprints, cookies, storage, and settings. It is designed for professionals who need multiple browser identities — whether for multi-account management, web automation, affiliate marketing, e-commerce, or privacy protection. The browser is built with Rust and TypeScript using the Tauri framework for the desktop shell and React for the UI. It leverages Camoufox (Firefox-based) and Wayfern (Chromium-based) as its anti-detection browser engines. ## Supported Platforms - macOS (Apple Silicon/ARM64) - Linux (x86_64) — available as .deb, .rpm, and AppImage - Windows (x86_64) ## Supported Browsers Donut Browser supports two browser engines: Wayfern (Chromium-based) and Camoufox (Firefox-based). ## Core Features (Always Free) - Unlimited local browser profiles with complete isolation - Anti-fingerprinting technology (Canvas, WebGL, Audio, and 100+ parameters) - Proxy support (HTTP, HTTPS, SOCKS4, SOCKS5) per profile - VPN support (WireGuard, OpenVPN) - Set as default browser with profile-specific link handling - Profile import from other browsers - Automatic browser updates - Local REST API for programmatic profile management - MCP (Model Context Protocol) server for AI tool integration - Full Puppeteer and Playwright compatibility ## Cloud & Paid Features Paid plans add cloud sync (up to 10 or 100 profiles depending on tier), team collaboration, profile sharing, mobile fingerprints, and premium residential proxy bandwidth. Cloud sync is also open source and can be self-hosted for single-user setups — see https://raw.githubusercontent.com/zhom/donutbrowser/refs/heads/main/docs/self-hosting-donut-sync.md ## Licensing The source code is licensed under the GNU Affero General Public License v3.0 (AGPL-3.0).

Additionally, Donut Browser has strong privacy by default. Unlike every other anti-detect browser, it does not track its users; whether it is by fingerprinting their device or monitoring their online activity. Donut Browser was designed to be a privacy tool first, and later evolved into a competitive anti-detect browser, offering advanced capabilities for both individuals and teams. ## Use Cases ### Multi-Account Management Create unlimited isolated browser profiles to run multiple accounts on any platform without detection. Each profile has unique fingerprints, cookies, and settings, so platforms cannot link them together. Useful for social media management, client work, and separating personal/work browsing. ### Web Scraping & Automation Automate browser tasks at scale without triggering bot detection. Donut Browser provides real browser profiles with authentic fingerprints, a local REST API for programmatic control, and MCP server support for AI tool integration. Fully compatible with Puppeteer and Playwright. ### Affiliate Marketing Run multiple ad accounts across platforms like Facebook and Google in completely isolated profiles. Each profile has unique fingerprints and can be assigned dedicated proxies for geographic targeting, preventing account linking and bans. ### E-Commerce Manage multiple seller accounts on Amazon, eBay, Etsy, Shopify, and other marketplaces. Isolated profiles with unique fingerprints and dedicated proxies prevent platform detection and account suspension. ### Airdrop Farming Operate multiple crypto wallets (MetaMask, Rabby, Phantom) in isolated profiles with unique fingerprints. Each profile prevents Sybil detection based on browser characteristics. Supports proxy assignment per wallet for geographic diversity. ### Privacy Protection Browse without being tracked or profiled. Each profile gets a randomized fingerprint, completely isolated cookies and storage, and optional VPN/proxy routing. Donut Browser is fully open source with zero telemetry — verifiable on GitHub. ## Privacy & Data Practices Unlike other anti-detect browsers that fingerprint users' devices, Donut Browser was designed with privacy as a core principle. The entire codebase is open source and auditable. - The browser operates entirely locally on the user's device - No browsing data, browser profiles, fingerprint data, or browser usage data is collected - For paid accounts: only email and name are collected for account management - Analytics use Simple Analytics (no cookies, no personal data, no IP tracking) - Payment details are processed by a third-party processor and never stored on Donut Browser servers - No selling, renting, or trading of personal information - No third-party advertising trackers - 30-day money-back guarantee on all paid plans (if proxy bandwidth is unused) ## Refund Policy 30-day money-back guarantee on all paid plans. Full refund within 30 days of purchase or renewal, provided the included proxy bandwidth has not been consumed.
