How to Scrape Websites with OpenClaw — Web Data Extraction Guide

Web scraping is a killer use case for OpenClaw. Unlike traditional scraping scripts that break whenever a site changes its HTML, OpenClaw can use browser automation to handle dynamic pages, CAPTCHAs, and login-gated content — and it understands context, so it extracts what you actually want rather than raw HTML.

Two Approaches: web_fetch vs. Browser

OpenClaw has two web extraction tools. Pick the right one:

• web_fetch — Fast, lightweight, for static HTML pages. Good for news sites, docs, simple data
• browser tool — Full Chromium instance. For JavaScript-heavy SPAs, login-required pages, or sites with anti-scraping measures

Simple Web Fetch Scraping

For straightforward pages, just describe what you want in a cron task:

openclaw cron add \
  --name "hex-competitor-pricing" \
  --schedule "0 9 * * 1" \
  --agent main \
  --task "Fetch the pricing pages of these 3 competitors: [urls]. Extract: plan names, prices, key features per plan. Compare against our pricing and flag if any competitor has changed their pricing since last week. Post findings to #competitive in Slack."

Browser-Based Scraping

For pages requiring JavaScript or interaction:

openclaw cron add \
  --name "hex-product-hunt-scrape" \
  --schedule "0 8 * * *" \
  --agent main \
  --task "Use the browser tool to open producthunt.com. Find today's top 5 launched products. For each: extract the product name, tagline, upvote count, and product URL. Save to a daily-launches.json file in the workspace."

Monitor a Competitor's Blog

openclaw cron add \
  --name "hex-competitor-content" \
  --schedule "0 10 * * 1-5" \
  --agent main \
  --task "Check the blog RSS feed or /blog page of [competitor URL]. Find any posts published in the last 24 hours. For each new post: extract the title, main topic, and key takeaways. Post a brief summary to #competitive in Slack."

Job Board Monitoring

openclaw cron add \
  --name "hex-hiring-signals" \
  --schedule "0 11 * * 1-5" \
  --agent main \
  --task "Search [competitor] careers pages for new job postings. Flag any roles related to: AI, automation, developer tools, or platform engineering. These are hiring signals — post findings to #competitive with direct links."

Data Cleaning and Structuring

One of OpenClaw's superpowers over traditional scrapers: it can understand the content and clean it up. Ask it to:

• "Extract all prices and normalize to USD"
• "Find the author, date, and summary for each article"
• "Identify the main CTA on this landing page"

Handling Anti-Scraping Measures

For sites with rate limiting: add delays to your task prompts. For sites blocking headless browsers: use the browser tool instead of web_fetch. For login-required content: use browser automation with stored credentials in .env.

"Scrape the data from [url]. If you get blocked or see a CAPTCHA, 
wait 30 seconds and try again. If still blocked after 2 attempts, 
post an alert to Slack and skip."
