It sits between your scraper and the target site, and it exposes a REST API that looks a lot like a normal HTTP request.<\/p>\n\n\n\n<p>Under the hood, it drives a real Chrome browser through Selenium with an undetected driver. That matters because Cloudflare&#8217;s checks look at browser behavior, not just headers.<\/p>\n\n\n\n<p><strong>\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435 \u0441\u0446\u0435\u043d\u0430\u0440\u0438\u0438 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u044f \u0432\u043a\u043b\u044e\u0447\u0430\u044e\u0442:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/nodemaven.com\/ru\/blog\/web-scraping\/\">Scraping sites<\/a> protected by Cloudflare&#8217;s managed challenge or JS challenge<\/li>\n\n\n\n<li>Grabbing a clearance cookie to reuse in a lightweight HTTP client afterward<\/li>\n\n\n\n<li>Automating access to sites that block plain requests libraries like requests or httpx<\/li>\n<\/ul>\n\n\n\n<p><strong>Good to know:<\/strong> FlareSolverr is a proxy layer, not a full scraping framework. You still write your own scraping logic. FlareSolverr just hands you the HTML once the challenge is out of the way.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-flaresolverr-works\">How FlareSolverr works<\/h2>\n\n\n\n<p>The flow is straightforward once you see it laid out.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Incoming request.<\/strong> Your script sends a POST request to FlareSolverr&#8217;s local API with a target URL.<\/li>\n\n\n\n<li><strong>Browser launches.<\/strong> FlareSolverr opens a Chrome instance (or reuses one from an active session).<\/li>\n\n\n\n<li><strong>Cloudflare challenge.<\/strong> The browser navigates to the URL and waits while Cloudflare runs its checks.<\/li>\n\n\n\n<li><strong>Cookies issued.<\/strong> Once the challenge clears, Cloudflare sets a clearance cookie in the browser.<\/li>\n\n\n\n<li><strong>Session handling.<\/strong> If you used a session, the browser and its cookies stay alive for reuse.<\/li>\n\n\n\n<li><strong>HTML returned.<\/strong> FlareSolverr sends back the final page HTML, headers, cookies, and the user agent it used.<\/li>\n<\/ol>\n\n\n\n<p>That last part matters. If you reuse the cookies in a different HTTP client, you need to match the user agent FlareSolverr reports, or Cloudflare throws the challenge again.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-should-you-use-flaresolverr\">When should you use FlareSolverr?<\/h2>\n\n\n\n<p>FlareSolverr is not the right tool for every scraping job. It is slower and heavier than a plain HTTP client because it runs a full browser per request or session.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Good fit<\/strong><\/td><td><strong>Poor fit<\/strong><\/td><\/tr><\/thead><tbody><tr><td>Sites behind Cloudflare&#8217;s JavaScript or Managed Challenge<\/td><td>Sites with no bot protection at all<\/td><\/tr><tr><td>Low to medium volume scraping jobs<\/td><td>High volume scraping that requires thousands of requests per minute<\/td><\/tr><tr><td>Obtaining a Cloudflare clearance cookie for reuse in subsequent requests<\/td><td>Sites protected by hard CAPTCHAs such as hCaptcha or reCAPTCHA<\/td><\/tr><tr><td>Occasional access to protected pages or stubborn API endpoints<\/td><td>Real time or latency sensitive workflows<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>For large scraping jobs, a lighter approach (<a href=\"https:\/\/nodemaven.com\/ru\/blog\/rotating-proxy\/\">\u0440\u043e\u0442\u0430\u0446\u0438\u043e\u043d\u043d\u044b\u0435 \u043f\u0440\u043e\u043a\u0441\u0438<\/a> plus a lean HTTP client, only falling back to FlareSolverr for challenged requests) usually performs better than routing everything through a browser.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-installing-flaresolverr\">Installing FlareSolverr<\/h2>\n\n\n\n<p>Docker is the recommended install path.
