Scrapfly Anti-bot Detector

Use it when

• Your scraper suddenly returns challenge pages and you need to identify which anti-bot vendor (Cloudflare, Akamai, DataDome, PerimeterX, Kasada) protects the site
• Before building a crawler you want to audit a site's CAPTCHA and browser-fingerprinting defenses to choose the right automation stack

What it solves

Not the fit when

• bypassing or automatically solving CAPTCHAs
• headless or CI pipelines - requires an interactive Chrome session
• browsers other than Chromium-based ones
• selector-rot
• geo-block
• rate-limit-throttle
• js-render-not-blocking

Install

Install from the Chrome Web Store (https://chromewebstore.google.com/detail/scrapfly/pdpakdgmjhkfimgaihlgaaiijlbilkca) or clone the repo and load its src/ folder as an unpacked extension via chrome://extensions with Developer mode enabled

Invoke

Navigate to the target site in Chrome, then click the extension icon to see detected anti-bot vendors, CAPTCHAs, and fingerprinting techniques with confidence scores; use the copy button to export detection data
