What is Charles Proxy: Traffic Inspection, Debugging, And Web Scraping Guide

Charles Proxy (or simply Charles) is an HTTP debugging proxy that acts as a man-in-the-middle between the computer and the internet, which developers and QA teams use to monitor, inspect, and modify data flow. In web scraping, it allows users to intercept, decrypt, and manipulate network traffic to extract data. This guide covers setup, core features, SSL handling, practical use cases, scraping workflows, troubleshooting, and notable alternatives of Charles Proxy.

Elixir Web Scraping: A Practical Step-by-Step Guide

Elixir web scraping solves one of the hardest problems in high-volume data collection: concurrency without thread overhead. The BEAM virtual machine (Erlang's runtime) runs each HTTP request as a lightweight process, not an OS thread, so you can fetch thousands of pages concurrently. If a process crashes, the supervisor restarts it automatically. This guide builds a complete Elixir scraper from scratch, covering static pages, paginated targets, JavaScript-heavy sites, and anti-bot countermeasures.

Playwright XPath: How to Locate and Interact With Elements

If you're building a Playwright scraper and not using Xpath, you're probably leaving your most precise location strategy on the table. Think of the DOM as a tree of nodes, and an XPath expression as the specific zip code to reach any node. In this article, we'll explain XPath fundamentals, how to construct XPath expressions, and how to interact with elements, including real-world examples.

Top Python Scraping Libraries: Overview, Comparison, and How to Choose the Right One

Python has the richest scraping ecosystem of any language. That breadth is exactly why making a choice is harder than it should be. This article continues from our Python web scraping guide, focusing on the selection problem: 8 libraries across 4 categories, what each one does best, where it breaks down, and how to choose the right one for the job.

Wait for Page to Load in Beautiful Soup: Why It Fails and How to Fix It

Waiting for a page to load when using Beautiful Soup is a common challenge in web scraping, especially when your scraper returns empty results because the page renders content via JavaScript. This happens because Beautiful Soup is a parser, not a browser, so it can’t execute JavaScript or wait for dynamic content to load. To handle this, you can use browser automation tools like Selenium or Playwright, a lightweight option like requests-html, or a Web Scraping API for production-grade workflows.

How to Fix SSLError in Python Requests: Causes and Solutions

An SSL error means the TLS handshake failed: your application encountered an SSL certificate it couldn't verify, so the connection was rejected. This issue commonly shows up during web scraping or when integrating with external APIs. In this guide, we'll explain what this error means, its causes, and walk you through the right fix for each.

How to Use a Cloudflare Scraper for Data Extraction

Cloudflare protects over 20% of all websites, and its anti-bot system can shut your scraper down in seconds. A Cloudflare scraper is any tool or script that gets past those defenses to pull data from protected sites. This guide breaks down how Cloudflare spots bots, why most scrapers fail, and how to scrape with Decodo's Web Scraping API.

Wait for Page to Load in Playwright: A Practical Guide to Every Waiting Method

Modern web apps don’t load everything at once, so running scripts too early leads to missed data, broken actions, and flaky results. In this guide, you'll learn how to handle waiting in Playwright, including how it behaves in a headless browser environment, covering auto-waiting, selectors, network events, timeouts, custom conditions, and error handling across dynamic pages.

undetected_chromedriver: Guide to Avoid Detection Online

Standard Selenium ChromeDriver is blocked by most protected websites in the first few requests. Anti-bot services like Cloudflare, DataDome, and HUMAN (formerly PerimeterX) can detect automation flags, WebDriver properties, and browser fingerprint gaps before the first page finishes loading. The undetected_chromedriver library patches ChromeDriver to reduce these detection signals and works as a drop-in Selenium WebDriver replacement. This guide shows what actually gets flagged, how the patches work, and how to fill the gaps with proxies and behavioral techniques.

How to Scrape Shopify Stores: Complete Developer Guide

Most Shopify stores have a built-in JSON endpoint for product data: prices, variants, inventory, images. Web scraping Shopify means requesting /products.json, paginating, and getting the catalog as JSON. But the endpoint is limited to 250 products per page, and some merchants disable it. This guide covers both: the JSON approach for stores that have it, and the fallback for stores that don't.

How to Scrape All Text From a Website: Methods, Tools, and Best Practices

Bulk text extraction has become an inseparable part of modern-day existence, with real-world cases including building datasets for LLM training, archiving, content analysis, and RAG systems. However, extracting all text is far more complex than scraping a single page, so we’ve prepared a step-by-step guide to discover pages, extract clean text, remove unnecessary elements, and export structured datasets into proper formats. The tools we use are Python, Beautiful Soup, Playwright, and Decodo proxies.

Crawl4AI Tutorial: Build Powerful AI Web Scrapers

Traditional scrapers return raw HTML. Turning that raw data into structured AI-ready data takes 50%+ extra engineering time, and pushing it directly into an LLM quickly becomes expensive at scale. Crawl4AI was built for that gap: Playwright rendering, automatic Markdown conversion, and native LLM extraction in one open-source framework. This guide takes you from a basic page crawl to production-ready structured data extraction.

How to Scrape Glassdoor: Tools, Methods, and Tips

Every Glassdoor scraping tutorial that uses Selenium or Playwright fails for the same reason: Cloudflare anti-bot protection fingerprints the TLS connection and blocks non-browser traffic. Glassdoor has internal API endpoints that return the same structured JSON that the frontend uses, without rendering a page. Because these endpoints accept standard HTTP calls, you can bypass Cloudflare by calling them with Python and curl_cffi for browser-grade TLS fingerprinting, plus Decodo residential proxies for IP rotation. This guide covers 4 complete scrapers for reviews, jobs, interviews, and company profiles.

How to Store Data in Sqlite: The Complete Guide From First Table to Production-Ready Database

SQLite runs inside every Android and iOS device, Python's standard library, and most embedded systems on the planet. The entire database lives in a single file, with no network layer, daemon, or config files to manage. That zero-overhead model makes it the default choice for web scrapers, mobile apps, CLI tools, and data pipelines that need structured storage without server complexity. This guide covers the full lifecycle: schema design, inserts, queries, security, and debugging.
