The open-source Camoufox alternative

Camoufox is a well-built open-source anti-detect browser — on Firefox. Clearcote takes the same engine-level, open-source philosophy to a de-Googled Chromium, so your automation blends in with the ~65% of the web that runs Chrome.

What is Camoufox?

Camoufox is an open-source anti-detect browser built on Firefox by the developer daijro. It patches the engine at the C++ level (via a customized Juggler) to inject a coherent fingerprint — canvas, WebGL, fonts, screen, navigator, WebRTC and locale — rather than spoofing from injected JavaScript, and exposes a Playwright-compatible Python interface. It's free, MPL-2.0 licensed, and genuinely respected in the space.

The core difference is the engine. Camoufox presents a Firefox identity; Clearcote presents a Chromium one. Because the overwhelming majority of real browsers are Chromium-based, a Chrome persona sits in a much larger, more ordinary crowd — and many detection models are tuned first and foremost against Chrome. If your targets expect Chrome, a Firefox fingerprint is the rarer thing to explain away.

Why teams pick Clearcote

A Chrome persona, not a Firefox one

Chromium is the majority of the web. A coherent Chrome identity blends into the largest anonymity set and matches what most detection models expect — where a Firefox fingerprint is inherently rarer.

Coherent down to the TLS handshake

Clearcote keeps the network layer consistent with the claimed Chrome version — the JA3/JA4 ClientHello follows the persona, not just the JavaScript. A browser that says Chrome should shake hands like Chrome.

Drop-in for the Chromium ecosystem

Playwright and Puppeteer, Python and Node, a standing CDP endpoint, a Docker image and an MCP server — Clearcote plugs into the tooling most automation already uses, with a one-line launch().

Reproducible and verifiable

Every change is a readable patch and every release is checksummed and signed, so you can verify the binary matches the source — the same open ethos Camoufox shares, on Chromium.

When Camoufox might be the better pick

  • You specifically want a Firefox identity — for targets that expect Firefox, or to diversify away from Chrome.
  • Your stack is already Firefox/Gecko-centric and you don't need Chromium's CDP ecosystem (Puppeteer, browser-use, Crawl4AI, Stagehand).
  • Camoufox is a mature, actively-maintained project — if a Firefox persona fits your use case, it's a solid, honest choice.

FAQ

Is Clearcote a drop-in replacement for Camoufox?

Not literally — Camoufox exposes a Firefox/Playwright-Python interface and Clearcote is Chromium with Playwright + Puppeteer for Python and Node. But both are engine-level and open-source, so the concepts transfer directly. Clearcote's launch() returns a standard Playwright Browser.

Is Camoufox or Clearcote better for bot detection?

It depends on the target. Most detection is tuned against Chrome, and a Chromium persona sits in a far larger crowd — so Clearcote's Chrome identity is usually the safer default. Camoufox is the right tool when you specifically need a Firefox identity.

Are both free and open source?

Yes. Camoufox is MPL-2.0; Clearcote ships readable patches and reproducible builds under a permissive license. Clearcote also offers an optional paid Pro build for teams who want the maintained binary and direct support.
