Donut's Mission
Donut Browser was created with a simple belief: you should have full control over what you share online. Every website you visit collects data about you — your device, your habits, your identity. Most of this happens without your knowledge or meaningful consent. Donut Browser exists to change that.
Why Donut Browser Exists
The modern web treats your data as a commodity. Companies track you across websites, build detailed profiles of your behavior, and link your personal life to your professional activity, your shopping habits to your health searches, and your social media presence to your real identity. Standard browsers offer little protection against this. Private browsing modes are inadequate — they don't prevent fingerprinting, and they don't let you maintain separate identities across different areas of your life.
Donut Browser started as a privacy tool built to solve this problem. It gives you the ability to create completely isolated browser profiles, each with its own unique fingerprint, cookies, and data. You decide whether your work browsing is connected to your personal browsing. You decide what information websites can see about you. You are in control.
Your Data, Your Choice
Every profile you create in Donut Browser is a clean slate. Websites see a unique browser with its own identity — they cannot link it to your other profiles or your real device. This means you can:
- Keep your work and personal browsing completely separate
- Prevent companies from building a comprehensive profile of your online activity
- Choose exactly what each website knows about you
- Maintain different identities for different purposes without cross-contamination
This is not about hiding. It is about having the same right to privacy online that you have offline — the right to share different things with different people.
Transparently Built
The Donut Browser app is open source under the AGPL-3.0 license. The profile manager, local API, MCP server, and sync service are all on GitHub for anyone to inspect and contribute to. There is no telemetry, no advertising, and no data collection.
The browser engines have a different model. Wayfern (Chromium-based) is proprietary — Chromium's permissive license makes it impossible to enforce AGPL, and open-sourcing it would invite others to commercialize the work without contributing back. Camoufox (Firefox-based) is largely open source with some proprietary anti-detection components. In both cases, keeping fingerprint spoofing code closed makes it harder for anti-bot companies to study and build targeted detection against it.
Donut Browser was built for privacy first and foremost, and the core browser with unlimited profiles, proxy and VPN support, and all essential features is free and always will be. It is built and maintained by a single developer with no venture capital and no investors. Your data is never monetized — a privacy tool that profits from your data would be a contradiction.
Paid plans are designed for professionals who use Donut Browser to earn a living — cloud sync, team collaboration, cookie and extension management, and a commercial license. Every subscription directly funds development. If a paid plan is not in your budget, you can still support the project by using it, reporting bugs, and requesting features you find valuable.
Looking Ahead
The long-term vision for Donut Browser is to make data control accessible to everyone, not just technically inclined users. Today, protecting your privacy online requires knowledge that most people don't have. Preventing cross-browser tracking, managing separate identities, and understanding fingerprinting are complex topics.
Donut Browser aims to make these protections trivially easy. The goal is a browser where any person, regardless of technical background, can control what data they share with which companies — and do so without needing to understand the underlying technology. Privacy should be the default, not a skill.
