Web Scraping API
Move from feasibility checks to hosted extraction and managed execution.
Open pathWeb scraping tool
To find out whether a website is scrapable, paste its URL above: Crawlora's free anti-bot checker runs a live bot-detection test and tells you which anti-bot or WAF vendor protects that page — Cloudflare Bot Management, DataDome, Akamai, PerimeterX, Kasada, Imperva, AWS WAF and more — identified from real response fingerprints, plus a 0–10 difficulty score and the lightest transport that actually got through. Difficulty is per-URL: a homepage is often wide open while a profile, product, or listing page is heavily protected — so check the exact target you intend to scrape, not just the domain.
Quick answer
Paste a URL to check whether that exact page is practical to scrape. Crawlora detects common anti-bot and WAF vendors, returns a 0-10 difficulty score, and names the lightest transport that worked, so you can decide whether plain HTTP, browser rendering, or a managed unblocker is needed.
Use this before you build a scraper — or point an AI agent at a site — to know exactly what you're up against on the precise page you want, not the homepage.

| Anti-bot vendor | Type | Confidence |
|---|---|---|
| Cloudflare | waf | high |
| DataDome | bot_management | high |
Live anti-bot checks on real sites: which vendor protects each URL and the lightest transport that actually retrieved it. Note how a homepage can be easy while a deep page on the same domain is hard.

Easy · 1/10Plain HTTP works — no anti-bot in the way.
Lightest transport that worked: direct HTTP

Easy · 1/10Akamai is present, but the homepage still loads over plain HTTP — vendor present ≠ blocking.

Hard · 6/10Same site as an easy homepage — but this deep profile page only yields to a real headless browser.
Lightest transport that worked: headless browser (JS render)

Enter the specific page you want to scrape — a profile, product, or listing, not just the homepage.
The probe tries plain HTTP, then a browser-impersonation request, then real headless and stealth browsers, stopping at the first one that retrieves the page.
Get a 0–10 difficulty score and band, whether it's scrapeable, the detected anti-bot vendors, and the lightest transport that worked.
Use Crawlora's hosted endpoints or unblocker to retrieve the page at scale with the recommended transport — pay only for what works.
Know before you build whether a target needs a simple HTTP request or a full stealth browser, on the exact page you care about.
The verdict names the lightest transport that worked, so you don't over-pay running a browser when plain HTTP would do — or waste time on HTTP when only a browser gets through.
See which vendor protects a site and the exact header/cookie evidence, useful for security research and competitive analysis.
Difficulty maps to cost: heavier transports cost more, so the score helps you budget a scraping project before you start.
The free checker is for one-off URL planning. Use the diagnostics API when a team needs to preflight target lists, estimate scrape complexity, choose transports, and budget production scraping before building pipelines.
