Open-source stealth browser

Owl Browser vs Camoufox

Camoufox is a free, open-source antidetect browser based on a customized Firefox build. It modifies fingerprint data in Firefox's C++ layer, rotates generated fingerprints, and exposes Playwright's automation API. It is licensed under MPL-2.0 and is a popular choice for open-source stealth scraping when budget is the priority.

Frequently asked questions

Is Owl Browser open source like Camoufox?

Camoufox is fully open source under MPL-2.0. Owl Browser publishes a free core called Owl Light on GitHub, while its full commercial engine is licensed. They also differ in browser base: Camoufox is Firefox-based and Owl Browser is Chromium-based.

Why choose Owl Browser over a free tool like Camoufox?

The main reasons are Chromium compatibility, low-latency high concurrency up to 256 contexts, agent-native rendering with an MCP server, and commercial support with active maintenance. If those do not matter and budget is the priority, Camoufox is a capable free option.

Do both tools work with Playwright?

Camoufox exposes the Playwright API directly. Owl Browser provides its own Python and Node SDKs plus a drop-in migration path for teams moving from Playwright and Puppeteer.
