Unblock

Browser fingerprinting allows websites to identify and track users across devices and sessions without relying on cookies. The W3C and major browser vendors flag it as a privacy threat that regulators are actively working to address. BotBrowser is an open-source, privacy-focused Chromium-based browser core designed to maintain a consistent fingerprint across operating systems. This guide covers its features, setup, validation, and practical use cases.

Traditional proxies hide your IP, but struggle against anti-bot systems like Cloudflare, DataDome, and Akamai. Webmaster unblockers, also known as Site Unblockers, are managed request layers that take a URL and return rendered HTML. This guide explains how they work, when to pick 1 over a proxy or Web Scraping API, and which 5 tools stand out in 2026.

Rank tracker getting blocked is a frustrating problem that SEO teams will certainly run across while they’re collecting search engine rankings. They open their rank tracking dashboard only to find empty SERP positions, error logs, stale data, or unexplained errors, with the rank tracker getting blocked. A rank tracker monitors where each page appears in search engine results pages (SERPs), but today’s anti-bot systems will often stand in the way of the requests, interrupting them before position data can be collected. This guide shows how to diagnose and fix the issues: why blocks happen, how to identify them, and what to do to get valid data.

Most Python scrapers that use Requests stop working as soon as a site is protected by Cloudflare. You might see a 403 error, get stuck in a redirect loop, or land on a "Just a moment..." page that never loads. Cloudscraper solves this problem without needing a headless browser. It builds on Requests, handles Cloudflare's JavaScript challenges, and gives you a working session. This guide explains how to set up Cloudscraper, configure proxies, choose an interpreter, handle CAPTCHAs, parse data, fix common errors, and understand the library's limitations. If you're new to Python scraping, start with the Python web scraping guide first.

When you scrape the web with Puppeteer, you almost always pull in data you want alongside extras you don't need, like images, fonts, and tracking scripts that increase your request count, slow your pages, and drain your proxy bandwidth. In this guide, you'll learn how to block unnecessary requests with request interception and Chrome DevTools Protocol (CDP) so your scraper runs faster and scales more efficiently.

A residential proxy network routes your traffic through real ISP-assigned home IPs. But how routing actually happens, which proxy types you end up using, and how IPs are sourced have a much bigger impact on success rates. This guide breaks down how residential proxy networks work, including ASN-level routing, the different types of IPs, and the protocols they support.

Node Unblocker is an open-source web proxy built on Node.js that allows users to bypass internet censorship, evade network filters, and access restricted content. Whether you are dealing with strict corporate firewalls, educational network restrictions, or geo-blocked websites, Node Unblocker acts as a seamless intermediary to securely route your web traffic.

Cloudflare is a massive global cloud network that sits firmly between your scraper and the data you need, blocking all requests that fail its multi-layered detection system. It powers nearly 21% of all websites globally, meaning that 1-in-5 sites rely on this network. Therefore, knowing how to bypass it is essential for serious scrapers. This practical walkthrough covers detection methods, tools like Puppeteer and Playwright, and both DIY approaches and managed solutions, including proxy strategies and web scraping APIs.

A node-fetch proxy routes your fetch requests through an intermediary server, so the target site sees the proxy's IP instead of yours. It's the standard fix for IP blocks, geo-restrictions, and rate limiting in Node.js scraping. The catch: neither node-fetch nor Node's native fetch supports proxies natively, so you need an external agent library to bridge the gap.

A 500 Internal Server Error means the server encountered a generic internal error while processing your request. It's frustrating because the message is deliberately vague. This guide is for you if you run a website, build or maintain applications, or send programmatic requests, whether you are fixing your own site or dealing with 500s from external targets while collecting data from the web.

Scraping Google can quickly turn frustrating when you're repeatedly met with CAPTCHA challenges. Google's CAPTCHA system is notoriously advanced, but it’s not impossible to avoid. In this guide, we’ll explain how to bypass Google CAPTCHA verification reliably, why steering clear of Selenium is critical, and what tools and techniques actually work in 2026.

CreepJS is a browser fingerprinting audit tool used to test how detectable your automated browser is. If you’re trying to bypass CreepJS or improve browser fingerprinting, it helps you spot inconsistencies across signals like WebGL, fonts, and navigator data. This guide shows what actually gets flagged and how to fix the parts that still give your browser away.

nodriver is a Python package for browser automation and web scraping built as the successor to undetected-chromedriver. It skips the usual WebDriver layer, talks to Chrome more directly than Selenium, and uses an async-first design. In this guide, you'll learn what nodriver is, how it works in Python, and where it fits for scraping JavaScript-heavy pages when basic browser automation starts showing its limits.

If you're scraping with Playwright or Selenium, you've hit this. Your script works on unprotected sites, but Cloudflare, PerimeterX (HUMAN Security), and DataDome detect the headless browser and block it within seconds. Stealth plugins help, but each browser update breaks the patches. Camoufox takes a different approach – it modifies Firefox at the binary level to spoof browser fingerprints, making automated sessions look like real user traffic. This guide covers Camoufox setup in Python, residential proxy integration, real-world test results against protected targets, and when browser-level tools aren't enough.

Web scraping is one of the most effective ways to collect publicly available data at scale, but without the right infrastructure, it often leads to a familiar roadblock: the “Your IP Address Has Been Banned” error. This message means a website has blocked your IP address after detecting automated or unusually frequent requests. Fortunately, IP bans are both fixable and preventable. In this guide, we explain what causes IP bans during web scraping, how to recover when one happens, and the best practices for keeping your scraping operations running smoothly without interruption.

A proxy server sits between your device and the internet and routes your traffic through an intermediary IP. It's core infrastructure for privacy, access control, and large-scale data operations. If you need to locate your proxy address and port, to set up a scraper, debug a failed connection, or audit your network, you'll want to know exactly where each platform stores these details. This guide covers every major OS, browser, and device, step by step.

You're trying to load a website, and instead of the page, you get a blank screen telling you access is denied. No explanation, no obvious reason. That's Error 1005, a Cloudflare security response that blocks your entire network rather than just your IP. This guide breaks down what triggers it, how to diagnose the cause, and what actually works to fix it.

TL;DR: A proxy server acts as an intermediary between your device and the internet, masking your IP address and routing your requests through alternative IPs. Businesses use proxies to bypass geo-restrictions, avoid blocks and CAPTCHAs, scrape web data at scale, verify ads, monitor prices, and maintain online anonymity. With the proxy market projected to reach USD 3.12 billion by 2032, understanding which proxy type fits your needs can make the difference between seamless data collection and constant roadblocks.
