Camoufox patches Firefox at the C++ level for undetectable fingerprint spoofing. Combined with a real 4G/5G mobile proxy, your sessions are indistinguishable from real phone users.
Every browser session generates a unique fingerprint — Canvas, WebGL, AudioContext, navigator properties, fonts, and screen resolution are all spoofed consistently. Camoufox patches Firefox at the engine level, not via JavaScript injection.
Each browser session is automatically paired with a real 4G/5G mobile IP. No separate proxy purchase needed. Available countries: DE, GB, FR, ES, PL, US. The TLS fingerprint matches the mobile IP type for maximum stealth.
Full Chrome DevTools Protocol access to every session. Connect with Playwright, Puppeteer, or any CDP client. Navigate pages, execute JavaScript, intercept network requests, and manipulate the DOM programmatically.
Capture full-page screenshots in PNG or JPEG. Execute arbitrary JavaScript in the page context. Extract data, fill forms, click elements, and handle dynamic content — all via the API.
Built on Camoufox — an open-source, Firefox 130+ based browser maintained by daijro with engine-level anti-fingerprinting patches. Canvas, WebGL, AudioContext, navigator, and timezone spoofing are applied at the C++ level, not via detectable JS overrides.
Pay per minute with USDC via the x402 protocol. No API keys, no registration, no monthly subscriptions. AI agents handle the HTTP 402 flow automatically. Settlement on Base (~2s) or Solana (~400ms).
Pay-per-minute with no commitment vs. monthly subscriptions. Mobile proxy included with every session.

Every session gets a unique fingerprint + real mobile IP. Indistinguishable from a real phone user.
Scrape sites protected by Cloudflare, DataDome, and PerimeterX. Each session has a unique fingerprint + real mobile IP, making requests indistinguishable from real users. No CAPTCHA challenges, no IP bans.
Manage multiple accounts on platforms like Instagram, TikTok, Facebook, and X/Twitter. Each account gets a unique browser fingerprint and mobile IP, preventing platform detection and linking of accounts.
Verify ad placements from real mobile user perspectives. See exactly what ads appear for real 4G/5G users in different countries. Detect malvertising, verify geo-targeting, and audit redirect chains.
Monitor competitor prices on Amazon, Walmart, and other retailers. Mobile fingerprint + mobile IP combination bypasses even the most aggressive anti-bot systems used by e-commerce platforms.
Give AI agents full browser control via MCP integration. Claude, GPT, and other LLMs can create sessions, navigate pages, fill forms, take screenshots, and extract data — all autonomously with USDC payment.
Access geo-restricted content and localized search results from 6 countries. See region-specific pricing, availability, and content as a real mobile user in that country would see it.
Most antidetect browsers (GoLogin, AdsPower) override browser APIs via JavaScript injection. Detection scripts can check for:
Camoufox patches Firefox at the C++ level. The JavaScript APIs return spoofed values natively — there are no overrides to detect. CreepJS, FingerprintJS, and BrowserLeaks see consistent, real-looking fingerprints.
Camoufox is open source, maintained by daijro on GitHub. Based on Firefox 130+. Read more: AI Browser Automation: Camoufox & Nodriver (2026) | Best Antidetect Browsers for Proxies (2026)
