--- ## What Is BotBrowser? BotBrowser is a privacy-first browser core designed to protect users from browser fingerprinting, a technique recognized as a privacy threat by W3C, major browser vendors, privacy regulators, and academic research ([see references](FINGERPRINT_PRIVACY.md)). It keeps fingerprint signals uniform across every platform, preventing tracking systems from collecting and correlating data to identify users. Run the same profile on Windows, macOS, or Linux and the fingerprint posture stays identical each time. All engineering focuses on privacy research, cross-platform tracking-resistance validation, and maintaining protected environments for authorized defensive benchmarking. Review the project [Legal Disclaimer](DISCLAIMER.md) and [Responsible Use Guidelines](RESPONSIBLE_USE.md) before using the software. --- ## Why BotBrowser > **What makes BotBrowser different:** Cross-platform privacy browser core with unified fingerprint technology that prevents tracking data collection and device linkage.| High-Fidelity, Always-Current Profiles including Android WebView and WebKit-family profile consistency, built on the latest stable Chromium so fingerprints stay aligned with current browser behavior and reduce stale-engine correlation risk | Network Stack Parity with Full-Proxy QUIC/STUN (UDP over SOCKS5) delivers Chromium-level tunneling so geo metadata does not leak and privacy labs maintain clean transport parity |
| Advanced Programmatic Control offers Playwright/Puppeteer integration with CDP leak blocking so privacy tooling leaves no telemetry residue | Distributed Privacy Consistency lets you verify privacy protection across multiple browser instances simultaneously with Mirror, synchronizing input and validating privacy posture in parallel |
| Per-Context Fingerprint enables independent fingerprint bundles per BrowserContext without spawning new processes, with millisecond-level switching and reduced memory overhead | Zero-Overhead Performance adds no measurable latency: Speedometer 3.0 within <1% of stock Chrome, zero fingerprint API overhead across macOS/Linux/Windows, 29% memory savings at scale with Per-Context Fingerprint, and a Trimmed Build (ENT Tier3) delivering 62% lower wall time and 85% faster per-context spin-up on Linux x64 |
