Parser for a complex site in Real time
Technical Challenges (Website Protection Systems)
Web Application Firewall (WAF)
A cloud filter (similar to Cloudflare) is used, which analyzes traffic and blocks suspicious requests using machine learning and behavior analysis.HTTP Header and Browser Fingerprint Verification
The system detects discrepancies in headers (for example, a conflict between User-Agent and header sets typical for real browsers).Automated Browser Detection
The protection recognizes headless browsers (Selenium, Puppeteer, Playwright) by the propertiesnavigator.webdriverand abnormal behavior.JavaScript Challenges and Dynamic Verification
JavaScript code runs on the client, collecting data about the device, OS, GPU, and response time, making emulation difficult.User Behavior Analysis
The system monitors the speed and frequency of requests, mouse movement, click sequences, and other signs of a real user.TLS and Canvas Fingerprinting
A unique connection fingerprint is created based on TLS parameters, OS, graphics card, and browser.IP Blocking and Reputation
Each IP receives a “trust score”; suspicious addresses require CAPTCHA or are blocked.WebSocket Connection Protection
Access to streaming data is only possible after receiving valid parameters from the site, complicating direct connections.

953 5 0 10 days500 USDHello, Slava, I am ready to complete your project.
I have good experience in bypassing website protections against parsing. Captchas, proxies, and special browsers. Extensive experience working with protection as a "black box," where the detection vector is maximally blurred.
I will select optimal services, like anti-captcha, based on the price/quality ratio.
I will provide long-term support at a reasonable price, as such a parser will not last long without constant updates.
You will provide the consumables for developing the parser, and I will provide complete reports, indicating what and where the expenses were incurred.

So far, it's difficult to say anything about your project. Can you send a link to the website and also describe what data needs to be parsed?

- To bypass trust issues with IP, a small microservice can be built that will take an IP from a proxy provider, check the trust score of the address against public databases, and either cancel its rental or pass it to the stealth browser profile.
- Solve captchas through third-party services, like capmonster.
- User behavior through emulating real behavior. For example: moving the mouse to an element along a Bézier curve, entering data with a delay, transparently intercepting responses from the server (instead of initiating own requests), etc.
You did not specify the website, so it is difficult to assess the volume of work in detail. The potential budget ranges from $2,500 to $7,000.

Може його тоді луче не парсити, раз вони нехочуть щоб ті дані так парсилися)
-
Може краще за опис було залишити посилання для аналізу?
-
Стільки погроз замість посилання?
-
У мене був у роботі веб-ресурс, який навіть зі звичайного браузера не всім давав заходити!
Ссилку в студію, бо ті заявки, що дають виконавці ні до чого якщо вони не зможуть! 😉
