Scores combine evidence from multiple detection methods. | | **Category Badge** | Color-coded badge: CAPTCHA, Anti-Bot, or Fingerprinting | | **Detection Methods** | Expandable details showing which methods triggered (DOM, cookies, headers, etc.) | ## Key Features ##### Multi-Layer Detection Four detection methods working together for maximum accuracy: - **DOM Inspection:** Scans HTML elements for CAPTCHA widgets - **Network Monitoring:** Analyzes HTTP headers and cookies - **JavaScript API Hooks:** Intercepts fingerprinting attempts - **Window Properties:** Detects injected security objects ##### Optimized Performance Built for speed with minimal browser overhead: - **12-hour caching:** Results cached per domain - **LRU pattern cache:** 60-80% faster pattern matching - **Early-exit detection:** Stops once match found - **~80% cache hit rate:** Typical performance metric ##### Detection History Track detections across all your browsing sessions: - **Session tracking:** View all past detections by website - **Filtering:** Search by domain or technology type - **Export:** Save results as JSON for analysis - **Configurable retention:** Set history limit in settings ##### Advanced Capture Tools Specialized tools for deep analysis of specific services: - **reCAPTCHA:** Extract sitekey and selectors - **Akamai:** Capture sensor data for analysis - **Imperva:** Extract challenge parameters - **Shape Security:** Analyze protection layers ##### Customizable Rules Tailor detection to your specific needs: - **Rules Editor:** Create custom detection patterns - **Import/Export:** Share rules with your team - **URL Blacklist:** Exclude specific domains from detection - **JSON-based:** Easy to modify and extend ##### Privacy-First Design Your data stays private: - **No data collection:** Zero telemetry or analytics - **100% local processing:** Everything runs in your browser - **No external requests:** No data sent to external servers - **Open source:** Fully auditable code on GitHub ## Common Use Cases ##### Web Scraping & Data Extraction **Scenario:** You're planning to scrape a website and need to know what security challenges to expect. **How Antibot Detector Helps:** - Quickly identify which anti-bot systems are protecting the site - Determine if CAPTCHAs are present (and which type) - Detect fingerprinting techniques that may block automated browsers - Plan your scraping strategy based on detected technologies > **Pro Workflow:** Use Antibot Detector to identify challenges, then use [Scrapfly's ASP feature](https://scrapfly.io/docs/scrape-api/anti-scraping-protection) to bypass them automatically without writing custom code. ##### Security Research & Penetration Testing **Scenario:** You're auditing a website's security posture as part of a penetration test. **How Antibot Detector Helps:** - Catalog all security layers protecting the application - Identify potential gaps in bot protection coverage - Document security technologies for reports - Compare security implementations across different pages ##### Competitive Analysis **Scenario:** You want to understand what security technologies competitors are using. **How Antibot Detector Helps:** - Quickly survey security stacks across multiple competitor sites - Identify industry trends in anti-bot adoption - Export historical data for trend analysis - Benchmark your own security against competitors ##### Learning & Education **Scenario:** You're learning about web security and want to understand how anti-bot systems work in practice. **How Antibot Detector Helps:** - See real-world examples of security technologies in action - Understand which detection methods reveal each technology - Compare different implementations across websites - Learn by examining the open-source detection logic ## Troubleshooting ##### Extension Icon Shows No Detections **Possible Causes:** - The website genuinely has no detectable anti-bot technologies - Detection hasn't completed yet (wait a few seconds after page load) - Extension is disabled or not properly loaded **Solutions:** 1. Refresh the page and wait 3-5 seconds for detection to complete 2. Verify the extension is enabled at `chrome://extensions` 3. Check the browser console for errors (F12 → Console tab) 4. Try a known-protected site like [nike.com](https://www.nike.com) (has Akamai) or [ticketmaster.com](https://www.ticketmaster.com) (has Cloudflare + Queue-it) ##### Detection Seems Slow or Delayed **Explanation:** First-time detection on a domain takes longer because the cache is empty. Subsequent visits to the same domain will be much faster (typically <1 second) due to 12-hour caching. **Expected Performance:** - **First visit:** 2-4 seconds (building cache) - **Cached visits:** <1 second (instant results) - **Cache hit rate:** ~80% for typical browsing patterns **Note:** Complex pages with many scripts may take slightly longer on first detection. ##### Extension Won't Load / Shows Errors **Common Issues:** - **Chrome Version:** Ensure you're using Chrome 88+ (Manifest V3 requirement) - **Folder Deleted:** The extension folder must remain in its original location - **Permissions:** Check file permissions allow Chrome to read the extension files - **Conflicting Extensions:** Other extensions may interfere (try disabling temporarily) **Reset Steps:** 1. Remove the extension from `chrome://extensions` 2. Delete and re-download/re-extract the extension files 3. Follow the [installation steps](#installation) again carefully 4. Check Chrome console for specific error messages ##### False Positives or Missing Detections **Why This Happens:** - Anti-bot services constantly evolve their implementations - Some services use conditional loading (only appear for suspicious traffic) - Detection rules may need updates for new service versions **How to Help:** 1. **Report false positives:** [Open a GitHub issue](https://github.com/scrapfly/Antibot-Detector/issues) with the URL and detected technology 2. **Report missing detections:** Include the URL and which technology you know is present 3. **Contribute rules:** Submit a pull request with updated detection JSON files *Detection accuracy improves with community contributions!* ## Frequently Asked Questions ##### Is Antibot Detector really free? Yes! Antibot Detector is **100% free** for personal and non-profit use under the [NPOSL-3.0 License](https://opensource.org/licenses/NPOSL-3.0). **Commercial use** (e.g., using it as part of paid services or within a company) requires a separate commercial license. Contact for commercial licensing inquiries. ##### Does it collect or send any data? **Absolutely not.** Antibot Detector is designed with privacy as a core principle: - ✅ **100% local processing** - all detection happens in your browser - ✅ **No telemetry** - zero analytics, tracking, or data collection - ✅ **No external requests** - doesn't communicate with any external servers - ✅ **Open source** - you can audit the entire codebase on [GitHub](https://github.com/scrapfly/Antibot-Detector) Your browsing data and detection results never leave your computer. ##### Will it work on Firefox, Edge, or Safari? Currently, Antibot Detector is **Chrome-only** (and Chromium-based browsers like Edge, Brave, Vivaldi). **Why Chrome-only?** The extension uses Chrome's Manifest V3 API, which provides the best security and performance. While technically possible to port to Firefox, it would require significant adaptation due to Firefox's different extension architecture. **Community contributions welcome:** If you're interested in porting to Firefox, feel free to fork the repo and submit a pull request! ##### Can I use this for commercial scraping projects? **License Requirement:** Commercial use requires a separate license. However, **Antibot Detector is best used as a reconnaissance tool**, not for production scraping. **Better Solution for Commercial Scraping:** - Use Antibot Detector to **identify** what protection a site uses - Use [Scrapfly's API](https://scrapfly.io/) to **bypass** those protections automatically - Scrapfly handles Cloudflare, DataDome, PerimeterX, Akamai, and more out-of-the-box This workflow (detect → bypass with Scrapfly) is much more reliable than trying to build custom bypass logic for each anti-bot system. ##### How accurate is the detection? Detection accuracy varies by technology type: | Category | Typical Accuracy | Notes | |---|---|---| | CAPTCHA | **95%+** | Very high accuracy due to distinctive DOM elements and scripts | | Anti-Bot | **85-90%** | Good accuracy, but some services use obfuscation | | Fingerprinting | **80-85%** | Harder to detect passive fingerprinting; works best for active techniques | **Confidence scores** help you gauge reliability - higher scores (80%+) indicate very reliable detection. ##### Can I add custom detection rules? Yes! Antibot Detector supports custom detection rules through the built-in **Rules Editor**: 1. Click the extension icon → **Settings** 2. Navigate to **Rules Editor** 3. Create a new JSON rule file or edit existing ones 4. Use the **Import/Export** feature to share rules with your team **Rule Structure:** Detection rules are JSON-based and specify patterns for cookies, DOM elements, URLs, headers, and more. **Contribute:** If you create rules for a new anti-bot service, please consider [submitting them as a PR](https://github.com/scrapfly/Antibot-Detector/pulls) to help the community! ##### How often is the extension updated? Antibot Detector is actively maintained with updates based on: - **New anti-bot services:** Rules added as new technologies emerge - **Service updates:** Existing rules updated when services change their implementations - **Bug fixes:** Issues reported by the community are addressed promptly - **Performance improvements:** Ongoing optimizations to detection speed **Stay updated:** Watch the [GitHub repository](https://github.com/scrapfly/Antibot-Detector) for release notifications, or check the [Releases page](https://github.com/scrapfly/Antibot-Detector/releases) for changelog details. **Auto-updates:** If you installed from the [Chrome Web Store](https://chromewebstore.google.com/detail/scrapfly/pdpakdgmjhkfimgaihlgaaiijlbilkca), updates are automatic. For manual installations, re-download the latest release and reload the extension. ## Related Resources ### Blog Posts [ **How to Know What Anti-Bot a Website Uses** Learn detection techniques and manual inspection methods ](https://scrapfly.io/blog/posts/how-to-know-what-anti-bot-website-uses) [ **How to Bypass Cloudflare Anti-Scraping** Complete guide to bypassing Cloudflare protection ](https://scrapfly.io/blog/posts/how-to-bypass-cloudflare-anti-scraping) [ **How to Bypass DataDome Anti-Scraping** Techniques for overcoming DataDome bot detection ](https://scrapfly.io/blog/posts/how-to-bypass-datadome-anti-scraping) [ **How to Bypass PerimeterX (HUMAN) Anti-Scraping** Methods for dealing with PerimeterX protection ](https://scrapfly.io/blog/posts/how-to-bypass-perimeterx-human-anti-scraping) [ **How to Bypass Akamai Anti-Scraping** Understanding and bypassing Akamai Bot Manager ](https://scrapfly.io/blog/posts/how-to-bypass-akamai-anti-scraping) ### Testing Tools [ **Canvas Fingerprint Tester** Test and analyze canvas fingerprinting techniques ](https://scrapfly.io/web-scraping-tools/canvas-fingerprint) [ **WebGL Fingerprint Tester** Examine WebGL-based fingerprinting methods ](https://scrapfly.io/web-scraping-tools/webgl-fingerprint) [ **Audio Fingerprint Tester** Test audio context fingerprinting detection ](https://scrapfly.io/web-scraping-tools/audio-fingerprint) [ **WebRTC Leak Tester** Check for WebRTC IP leaks and tracking ](https://scrapfly.io/web-scraping-tools/webrtc-leak) ### Scrapfly Products [ **Anti-Scraping Protection (ASP)** Automatically bypass anti-bot systems detected by Antibot Detector ](https://scrapfly.io/docs/scrape-api/anti-scraping-protection) [ **Scrapfly API** Complete web scraping API with built-in anti-bot bypass ](https://scrapfly.io/) ### Install & Download [ **Chrome Web Store** One-click install with automatic updates (recommended) ](https://chromewebstore.google.com/detail/scrapfly/pdpakdgmjhkfimgaihlgaaiijlbilkca) [ **GitHub Releases** Download for manual installation ](https://github.com/scrapfly/Antibot-Detector/releases) ### Source Code & Development [ **GitHub Repository** View source code, contribute, and report issues ](https://github.com/scrapfly/Antibot-Detector) [ **Contribution Guide** Learn how to contribute new detectors and improvements ](https://github.com/scrapfly/Antibot-Detector/blob/main/CONTRIBUTING.md) **Need Help?** If you have questions or need assistance with Antibot Detector, [open an issue on GitHub](https://github.com/scrapfly/Antibot-Detector/issues) or reach out to .
