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.\n\nAll 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.\n\n---\n\n## Why BotBrowser\n\n> **What makes BotBrowser different:** Cross-platform privacy browser core with unified fingerprint technology that prevents tracking data collection and device linkage.\n\n\u003Ctable cellspacing=\"0\" cellpadding=\"8\">\n  \u003Ctr>\n    \u003Ctd width=\"50%\">\u003Cstrong>High-Fidelity, Always-Current Profiles\u003C\u002Fstrong> including Android WebView, built on the latest stable Chromium so fingerprints always match current browser behavior and trackers cannot key on stale engines\u003C\u002Ftd>\n    \u003Ctd width=\"50%\">\u003Cstrong>Network Stack Parity\u003C\u002Fstrong> with \u003Ca href=\"ADVANCED_FEATURES.md#network-fingerprint-control\">Full-Proxy QUIC\u002FSTUN\u003C\u002Fa> (UDP over SOCKS5) delivers Chromium-level tunneling so geo metadata does not leak and privacy labs maintain clean transport parity\u003C\u002Ftd>\n  \u003C\u002Ftr>\n  \u003Ctr>\n    \u003Ctd width=\"50%\">\u003Cstrong>Advanced Programmatic Control\u003C\u002Fstrong> offers \u003Ca href=\"examples\u002F\">Playwright\u002FPuppeteer integration\u003C\u002Fa> with CDP leak blocking so privacy tooling leaves no telemetry residue\u003C\u002Ftd>\n    \u003Ctd width=\"50%\">\u003Cstrong>Distributed Privacy Consistency\u003C\u002Fstrong> lets you verify privacy protection across multiple browser instances simultaneously \u003Ca href=\"tools\u002Fmirror\u002F\">with Mirror\u003C\u002Fa>, synchronizing input and validating privacy posture in parallel\u003C\u002Ftd>\n  \u003C\u002Ftr>\n  \u003Ctr>\n    \u003Ctd width=\"50%\">\u003Cstrong>Per-Context Fingerprint\u003C\u002Fstrong> enables \u003Ca href=\"PER_CONTEXT_FINGERPRINT.md\">independent fingerprint bundles per BrowserContext\u003C\u002Fa> without spawning new processes, with millisecond-level switching and reduced memory overhead\u003C\u002Ftd>\n    \u003Ctd width=\"50%\">\u003Cstrong>Zero-Overhead Performance\u003C\u002Fstrong> adds \u003Ca href=\"BENCHMARK.md\">no measurable latency\u003C\u002Fa>: Speedometer 3.0 within <1% of stock Chrome, zero fingerprint API overhead across macOS\u002FLinux\u002FWindows, 29% memory savings at scale with Per-Context Fingerprint, and a \u003Ca href=\"BENCHMARK.md#trimmed-build\">Trimmed Build\u003C\u002Fa> (ENT Tier3) delivering 62% lower wall time and 85% faster per-context spin-up on Linux x64\u003C\u002Ftd>\n  \u003C\u002Ftr>\n\u003C\u002Ftable>\n\n### Cross-Platform Fingerprint Protection\n\n- Single profile, every host OS: identical UA, screen metrics, touch surfaces, fonts, and device APIs on Windows, macOS, Linux (ENT Tier1), Android (PRO), and WebView (ENT Tier3) so trackers see the same fingerprint everywhere.\n- Built-in configuration handles touch simulation, device metrics, and locale\u002Ftimezone detection from the proxy IP while still allowing CLI overrides when privacy experiments require them.\n- Quick demos: [▶️ CreepJS Android](\u002F\u002Fbotswin.github.io\u002FBotBrowser\u002Fvideo_player\u002Findex.html?video=antibots-creepjs-creepjs-Android) • [▶️ Iphey](\u002F\u002Fbotswin.github.io\u002FBotBrowser\u002Fvideo_player\u002Findex.html?video=antibots-iphey-iphey-Android) • [▶️ Pixelscan](\u002F\u002Fbotswin.github.io\u002FBotBrowser\u002Fvideo_player\u002Findex.html?video=antibots-pixelscan-pixelscan-Android)\n\n---\n\n## Getting Started\n\n### Quick Start\n\n**Step 1: Download**\n- [Latest release](https:\u002F\u002Fgithub.com\u002Fbotswin\u002FBotBrowser\u002Freleases) for your OS\n- [Demo profile](profiles\u002F) (any `.enc` file)\n\n**Step 2: Launch**\n- **GUI:** Use [BotBrowserLauncher](launcher\u002F) for one-click profile selection and multi-instance management\n- **CLI** (use absolute paths):\n  ```cmd\n  chrome.exe --bot-profile=\"C:\\absolute\\path\\to\\profile.enc\" --user-data-dir=\"%TEMP%\\botprofile_%RANDOM%\"\n  ```\n- macOS\u002FLinux commands follow the same pattern; see [INSTALLATION.md](INSTALLATION.md) for full instructions.\n\n**Step 3: Verify**\n- Visit [CreepJS](https:\u002F\u002Fabrahamjuliot.github.io\u002Fcreepjs\u002F) or your preferred tracking observatory to confirm identical privacy posture.\n- Timezone\u002Flocale\u002Flanguage auto-derive from your proxy\u002FIP; override via CLI only when needed.\n\n\n**[Complete Installation Guide →](INSTALLATION.md)**\n\n### Minimal Playwright Example\n\n```javascript\nconst browser = await chromium.launch({\n  headless: true,\n  executablePath: BOTBROWSER_EXEC_PATH,\n  args: [`--bot-profile=${BOT_PROFILE_PATH}`,\n  '--proxy-server=socks5:\u002F\u002Fusr:pwd@127.0.0.1:8989']  \u002F\u002F or: http:\u002F\u002Fusr:pwd@127.0.0.1:8989\n});\nconst page = await browser.newPage();\nawait page.addInitScript(() => { delete window.__playwright__binding__; delete window.__pwInitScripts; });\nawait page.goto('https:\u002F\u002Fabrahamjuliot.github.io\u002Fcreepjs\u002F');\n```\n\n**Notes:**\n- Use `--user-data-dir` with a unique temporary folder to avoid conflicts with running Chromium instances\n- Prefer `--proxy-server` or [per-context proxies](PER_CONTEXT_FINGERPRINT.md) (ENT Tier1); auto timezone\u002Flocale detection applies in both cases\n- Avoid framework-specific proxy\u002Fauth options (e.g., `page.authenticate()`), which disable BotBrowser's geo-detection and may leak location information\n\nExamples: [Playwright](examples\u002Fplaywright\u002F) • [Puppeteer](examples\u002Fpuppeteer\u002F)\n\n**More options:**\n- Framework-less approach: [`--bot-script`](CLI_FLAGS.md#--bot-script) + [CDP](examples\u002Fbot-script\u002F) (privileged context, earlier hook, fewer artifacts)\n- Docker: [docker\u002FREADME.md](docker\u002F)\n- Full flags: [CLI_FLAGS.md](CLI_FLAGS.md)\n\n\u003Ca id=\"builds\">\u003C\u002Fa>\n## Builds\n\nBotBrowser ships in two builds. Both share the same fingerprint protection model, the same profile format, the same CLI flag surface, and the same CDP commands.\n\n| | Standard Build | Trimmed Build (ENT Tier3) |\n|---|---|---|\n| **Distribution** | Public [releases](https:\u002F\u002Fgithub.com\u002Fbotswin\u002FBotBrowser\u002Freleases) | Enterprise channel only |\n| **Built for** | Long-running and interactive sessions | Short-session, high-concurrency automation |\n| **Browser feature surface** | Full | Tuned for short-session workloads |\n| **Fingerprint protection** | Same | Same |\n| **Per-Context Fingerprint** | Same | Same |\n| **Profile compatibility** | Same | Same |\n\n**Linux x64 benchmark (400 official samples, `1..20 contexts × 10 repeats × 2 builds`)**: Trimmed Build cuts wall time by **62%**, per-context creation by **85%**, first navigation by **38%**, CPU peak by **68%**, PSS peak by **31%** versus Standard, with **100% success rate** and **0 residual processes** for both builds.\n\nTrimmed Build is the right choice when context spin-up dominates total wall time, when CPU peak per context limits density, or when shared memory is the binding constraint. Standard Build remains the right choice for interactive workflows and scenarios that exercise the full browser feature surface.\n\nProduct overview, engineering design, FAQ: [TRIMMED_BUILD.md](TRIMMED_BUILD.md).
