For Any Website

Built-In Cloudflare Bypass in Net::HTTP

A-Parser's built-in Net::HTTP scraper collects data from websites and supports automatic bypass of Cloudflare challenges using Chrome.

JA3, JA3N, JA4, JA4H, and Akamai Fingerprints

Some websites analyze connection and request parameters to distinguish scrapers from regular browsers. A-Parser's built-in HTTP client reproduces the TLS and HTTP/2 fingerprints of Chrome for Windows and Android.

  • JA3, JA3N, and JA4. Reflect TLS client parameters during connection establishment.
  • JA4H. Describes the HTTP request: its method, protocol version, and headers.
  • Akamai. Reflects HTTP/2 connection settings and pseudo-header order.

This makes A-Parser requests look like Chrome requests in terms of connection parameters, helping avoid blocks during data collection.

How It Works

Choose How to Handle CAPTCHAs

Bypassing CAPTCHA challenges during web scraping: connect a compatible solving service or use an automatic method if your scraper supports it.
Connect a CAPTCHA-Solving Service

Choose a compatible service, enter your key, and save the settings to a preset. Then use it in a built-in or custom JS scraper.

Use Automatic Methods

Cloudflare Turnstile can be solved without a CAPTCHA-solving service: in Auto mode, A-Parser uses a browser. This method is available in scrapers that support Util::Turnstile. Automatic bypass of Yandex SmartCaptcha is also available in Wordstat scrapers.
