Retailers are quietly adjusting the prices you see based on your ZIP code, browsing history, and device type. The FTC calls it "surveillance pricing." New York just became the first state to mandate disclosure when algorithms set personalized prices. As this practice scales globally, proxies and web data collection solutions are emerging as the key tools for both competitive intelligence and regulatory enforcement.

An SSL proxy, often called an HTTPS proxy, is an intermediary server that forwards web requests between a user and a website through an encrypted HTTPS connection. Instead of connecting directly to the destination server, the client routes traffic through the proxy, which helps secure data transmission and manage outgoing requests.

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.

Sony has been quietly testing dynamic pricing on the PlayStation Store, showing different users different prices for the same games. First spotted by a Reddit user and later confirmed through API tracking, the experiment now spans over 190 titles across 70+ regions. Here's what we know so far, how it could affect your purchasing decisions, and what savvy shoppers can do to make the most of it.

Images, video, and audio are harder to collect and clean than text, and much less useful without context. Multimedia scraping helps you collect media, preserve the metadata that gives it meaning, and turn scattered files into training-ready datasets. The hard part is treating each media type differently from the start.

Pokémon card drops in 2026 are basically a shiny encounter with a 1 in 4096 spawn rate – except everyone else has a master ball and you're still throwing regular ones, letting opportunities escape you. Limited releases sell out in seconds, scalpers run automated lineups, and manual shoppers don't stand a chance. This guide gives you the full setup: the right bot, the right proxies, and the tricks to catch 'em all.

Yelp doesn't make scraping easy. The data you need is spread across multiple backend systems (no single endpoint gives you everything), and standard HTTP libraries get blocked before the first response. This guide covers every extraction method with Python, including the TLS impersonation and anti-bot techniques you need to avoid blocks at scale.

A bootstrapped data operation found that their web scrapers crawled to a halt as they tried to scale from 100 to 10,000 URLs. This is a common challenge with sequential processing and exactly why understanding concurrency vs parallelism is key to building efficient, scalable systems. This guide explains both concepts, their key differences, and limitations, so you can quickly decide the best mechanism for your project.

Most scraping APIs treat every request the same – maximum power, maximum cost. But real workloads are mixed: simple HTML pages, JavaScript-heavy targets, and protected sites that need premium proxies. If your pipeline covers all three, you’re paying worst-case prices on every request. We built a scraping API that matches cost to complexity, one request at a time.

Switching from ChatGPT to Claude no longer means starting from scratch. Anthropic’s memory import tool lets you transfer preferences, context, and instructions in under 5 minutes. This guide covers 3 migration paths – from a quick memory import to a full data transfer, plus feature comparisons, export steps, and power tips.

Requests, HTTPX, and AIOHTTP all make HTTP requests, but they differ in how they handle concurrency. Requests is synchronous and has been the default since 2011. HTTPX gives you both sync and async with HTTP/2 support. AIOHTTP is async-only and faster at high concurrency, but has a steeper learning curve. The right choice depends on your async model, whether you need WebSockets or HTTP/2, and how much code you're willing to rewrite. This article covers architecture, performance data, proxy setup, migration paths, and common mistakes in production scraping setups.

TL;DR: A web crawler is a program that systematically navigates the web by following links from page to page. Python is the go-to language for building crawlers thanks to libraries like Requests, Beautiful Soup, and Scrapy. This guide covers everything from your first 50-line crawler to a production-grade Scrapy setup with proxy integration, JavaScript rendering, and distributed architecture. If you've ever had to collect data from hundreds or thousands of pages and done it manually, this is for you.

Scrapy is a powerful web scraping framework available in Python. Its asynchronous architecture makes it faster than sequential scrapers built with Requests or Beautiful Soup, and it includes everything needed for production-ready scraping: spiders, items, pipelines, throttling, retries, data export, and middleware. In this guide, you'll learn how to set up Scrapy, build and customize spiders, handle pagination, structure and store data, extend Scrapy with middlewares and proxies, and apply best practices for scraping at scale.
