About this site

A field guide to scraping the modern web.

What is webscraping.space?

webscraping.space is a focused, no-fluff blog about web scraping. The practice of programmatically extracting data from websites. We publish practical tutorials and field notes covering the full lifecycle of a scraper: fetching pages, parsing HTML, dealing with JavaScript-rendered content, surviving anti-bot defenses, and running reliably at scale.

Who is behind it?

Written by a small group of engineers who have spent years building production data pipelines that lean on scraping when no API exists. We have been blocked, fingerprinted, honeypotted, and rate-limited. The guides here are the lessons that survived.

What we cover

• Fundamentals: HTTP, the DOM, CSS and XPath selectors, the request/response cycle.
• Python: requests, httpx, BeautifulSoup, lxml, Selectolax.
• Node.js: undici, cheerio, Playwright, Puppeteer.
• Anti-bot: TLS/JA3 fingerprinting, Cloudflare, PerimeterX, CAPTCHAs, proxies.
• Scaling: queues, concurrency, caching, dedup, polite rate limits.
• Ethics and law: robots.txt, terms of service, public data, and when not to scrape.

Our scraping principles

1. Respect robots.txt unless you have a clear, ethical reason not to.
2. Rate-limit yourself more strictly than the target ever will.
3. Prefer official APIs and bulk datasets over scraping when they exist.
4. Do not scrape personal data you do not need.
5. Cache aggressively. Never re-request what you already have.

How we test

Every code sample is run against a local fixture or a sandbox target before publication. Where a post depends on a live third-party site, we mark it with the date tested and re-verify quarterly. Scrapers rot. We try not to ship rotten ones.

Stay in the loop

The easiest way to keep up is the RSS feed. Drop it into your reader of choice. We also publish a sitemap for the crawlers.
