Unlimited isolated profiles
Create unlimited local browser profiles, each with its own cookies, storage, extensions, and fingerprint so sessions stay isolated.
Donut Browser
Free, open-source anti-detect browser for Windows, macOS, and Linux with unlimited local profiles, per-profile fingerprints, proxy and WireGuard support, and local automation interfaces.
Overview
Donut Browser is a free, open-source anti-detect browser for Windows, macOS, and Linux. It is built around unlimited local profiles, with each profile keeping its own fingerprint, cookies, storage, and extensions so browsing identities stay separated on the same machine.
The product is designed for people who need separated browser identities, proxy-based routing, and local automation. The source also describes a desktop app with a local REST API and MCP server, plus Pro and Team upgrades for browser manipulation, profile backup, collaboration, and cloud sync.
Features
Per-profile proxy support
Attach HTTP, HTTPS, SOCKS4, or SOCKS5 proxies to individual profiles, with support for basic auth, IP-allowlist, and dynamic proxy URLs.
WireGuard VPN per profile
Route a profile through WireGuard by dropping in a .conf file so the profile’s country, ASN, and timezone match the network path.
Local automation interfaces
Run browser management from localhost through a REST API and MCP server instead of a cloud dashboard.
Profile organization and handoff
Group profiles, import cookies, import/export extensions, and set Donut as the default browser for specific links.
Optional self-hosted sync
Self-host sync with the optional Docker server and encrypted storage, so profiles, proxies, and groups can stay in sync across devices.
Use Cases
Separated everyday browsing
Keep personal, work, and client identities in separate local profiles so cookies, storage, and fingerprints do not overlap. Each profile can also be set as the default target for links.
Multi-account operations
Manage multiple social, marketplace, or ad-platform accounts from isolated browser identities. The source highlights per-profile proxies, timezone matching, and profile grouping for account work.
Web scraping and browser automation
Drive profiles from a local REST API or MCP server, and on Pro plans connect to a Chrome DevTools Protocol port per profile for Puppeteer, Playwright, or Selenium.
Crypto and Web3 sessions
Use one profile per wallet or account and keep browser state separate for MetaMask, Phantom, Rabby, and Keplr. The privacy page frames this as a way to isolate cookies, fingerprint, and proxy per identity.
Cross-device profile sync
Sync profiles, proxies, and groups across devices with the optional self-hosted Docker sync server when you need the same browser setup in more than one place.
