Donut Browser Review 2026: Free, Local and Open
Donut Browser review: unlimited free local profiles, an AGPL-3.0 app, a Chromium engine with C++ spoofing and Linux packages. Scored 93.0/100.
Donut Browser is an open-source, local-first profile manager on a native Chromium fingerprint engine. It launched in 2025 and is first in our ranking with 93.0 out of 100.
Verdict
The best free antidetect browser, and the best overall for most users. You get unlimited profiles with full fingerprinting at $0, no account, and an app you can audit. The closed engine and paid automation are the trade-offs.
Scores
| Criterion | Weight | Score | Note |
|---|---|---|---|
| Fingerprint engine | 22% | 9 | Chromium fork with spoofing in C++ |
| Local-first privacy | 18% | 10 | Local by default, no account, no incidents |
| Free tier | 14% | 10 | Unlimited local profiles at $0 |
| Open source | 12% | 8 | App is AGPL-3.0; engine is closed |
| Automation and API | 12% | 9 | Local API and CDP; MCP on paid plans |
| Platforms | 10% | 10 | Windows, macOS and Linux, five package formats |
| Profile management | 8% | 9 | Groups, proxies, cookies, extensions, ephemeral profiles |
| Price at scale | 4% | 9 | Local profiles are free at any count |
Engine
Profiles run on its own Chromium-based engine. Fingerprints are patched in C++, not injected with JavaScript, so there are no page-level hooks for toString or descriptor checks to find. Donut Browser used Camoufox (Firefox) before. It moved to its Chromium engine in mid-2026 and removed Camoufox in v0.28.0 in July 2026. Why that matters: Chromium vs Firefox antidetect browsers.
Privacy
There is no account. Profiles stay on your machine. Sync is optional, end-to-end encrypted and self-hostable. There is no known incident. Compare that with the breaches at two cloud vendors.
Free plan and pricing
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Unlimited local profiles, full fingerprinting, proxies, WireGuard, local API |
| Solo | $29/mo | 20 cloud backups, remote MCP, commercial use |
Automation
Donut Browser has a local REST API and exposes CDP for Playwright, Puppeteer and Selenium. It also supports MCP. Browser automation and MCP control need a paid plan.
Platforms
Windows, macOS and Linux. Linux gets AppImage, deb, rpm, Flatpak and Snap. Most rivals ship Linux partly, through Docker, or not at all.
Donut Browser vs Multilogin
Donut Browser wins 5 of 8 criteria, Multilogin wins 1.
Multilogin is older and has proxy traffic and Android cloud phones in one plan. It scores 10 on profile management against Donut Browser’s 9.
