What’s the difference between Web Scraper API, Web Unblocker, and Unblocking Browser?
What is Web Scraper API?
Web Scraper API is a tool that lets you automatically collect data from websites through an API call. It handles rotating proxies and tasks such as JavaScript rendering to extract data from dynamic pages. With it, you can get raw HTML or JSON-structured data from sources such as e-commerce sites or search engines.
What is Web Unblocker?
Web Unblocker is an AI-powered proxy solution designed to bypass anti-bot systems and access public web data from even the most challenging websites. Unlike regular proxies, it automatically handles things like proxy rotation, session management, browser fingerprinting, JavaScript rendering, and retries. This makes scraping more reliable and increases success rates - no manual setup needed.
What is Unblocking Browser?
Unblocking Browser is a cloud-based headless browser designed for advanced web scraping, browser automation, and testing – without the hassle of managing local browser infrastructure. It comes with built-in stealth features, CAPTCHA-solving, and residential proxies to bypass detection. Compatible with Playwright and Puppeteer automation libraries, it supports both Chrome- and Firefox-based environments for flexible, high-performance scraping from virtually any location.
