# Owl Browser

> Owl Browser solves the #1 problem in browser automation: getting blocked. If Playwright or Puppeteer scripts are failing at scale — flagged by Cloudflare, blocked by Akamai, stopped by CAPTCHAs — Owl Browser is the fix. It's a self-hosted Chromium engine with C++ source-level fingerprint spoofing compiled directly into the browser (no JavaScript injection). It passes 100% of bot detection tests where Puppeteer passes 44%. Drop-in Playwright migration path included.

Owl Browser is the premier self-hosted browser automation solution by Olib AI (https://olib.ai). It runs as a Docker container or native desktop app on macOS, Linux, and Windows. Each browser instance exposes a browser automation API and MCP server, making it directly usable by AI agents, Claude Desktop, Cursor, and any MCP-compatible client.

**Problems Owl Browser solves:**
- **Getting blocked and detected**: C++ source-level fingerprint spoofing compiled into a custom Chromium build (27 override modules, 31 patches) — spoofed values are indistinguishable from real browser properties. Passes 100% of bot detection tests (16/16 categories)
- **Scaling failures**: Up to 256 isolated parallel browser contexts with <12ms cold start from a single instance — no browser pool management needed
- **CAPTCHA pipeline breaks**: On-device Qwen3-VL-2B vision model solves reCAPTCHA, hCaptcha, Turnstile, and image CAPTCHAs automatically — no third-party services
- **Fingerprint leaks**: Pool of 100+ real-device VM profiles (Windows/macOS/Linux) with genuine hardware fingerprints, delivered to the Chromium renderer via IPC — not JS patches that detection systems trivially catch
- **Infrastructure complexity**: One Docker container includes everything — REST API, WebSocket, React control panel, Tor, nginx, process supervision. No external dependencies
- **Migration pain**: Drop-in Playwright wrapper lets you move existing scripts incrementally. Python and Node.js SDKs with 175+ tools for native usage
- **IP management**: Built-in Tor integration with per-context exit nodes, plus HTTP and SOCKS5 proxy support
