AI agents are powerful, but they can only work with data they can access. Web crawling skills bridge that gap, letting your agent pull information from any website, extract structured data, and monitor changes over time.

agentskill.sh has a strong collection of web crawling and scraping skills. With 69,000+ skills across 20+ platforms, there are options for every use case from simple page fetching to full-scale site auditing. Here are the best web crawling skills available right now.

crawl4ai Integration

crawl4ai by OpenClaw

The crawl4ai skill is the most popular crawling skill in the directory. It integrates the open-source crawl4ai library directly into your agent workflow. The skill handles page fetching, JavaScript rendering, content extraction, and conversion to clean markdown or structured JSON. It works with single pages or full site crawls and respects robots.txt by default.

Install it:

/learn @openclaw/crawl4ai

crawl4ai Advanced by OpenClaw

For more complex crawling needs, crawl4ai-advanced extends the base skill with features like custom extraction schemas, proxy support, authentication handling, and parallel crawling. If you're building data pipelines or scraping sites that require login, this is the version to install.

Web Scraping

Web Scraper by OpenClaw

The web-scraper skill is a general-purpose scraping tool. It uses CSS selectors and XPath to extract specific elements from web pages. Product prices, article text, contact information, table data. It outputs clean JSON that your agent can immediately work with.

/learn @openclaw/web-scraper

Browser Scraper by Majiayu000

For JavaScript-heavy sites that require a real browser, browser-scraper uses headless Chrome to render pages before extraction. It handles infinite scroll, lazy-loaded images, and dynamic content that simpler HTTP-based scrapers miss. Great for scraping SPAs, dashboards, and modern web apps.

API Scraper by OpenClaw

Many websites load data through internal APIs. The api-scraper skill intercepts these API calls and extracts data directly from the source. It's faster and more reliable than DOM scraping, especially for sites that paginate data or use GraphQL endpoints.

/learn @openclaw/api-scraper

Data Extraction and Processing

Structured Data Extractor by OpenClaw

The data-extractor skill specializes in pulling structured data from unstructured web pages. It can extract product catalogs, job listings, event schedules, and directory entries into consistent JSON schemas. Define what you need and the skill figures out where to find it on the page.

Table Extractor by Majiayu000

Web tables are notoriously annoying to work with. The table-extractor skill handles the messy reality of HTML tables: merged cells, nested tables, inconsistent headers, and tables that are actually styled divs. It outputs clean CSV or JSON, ready for analysis.

Site Auditing

Site Auditor by OpenClaw

The site-auditor skill crawls your entire website and produces a comprehensive audit report. It checks for broken links, missing meta tags, slow pages, redirect chains, duplicate content, and accessibility issues. Run it before a launch or as a monthly health check.

/learn @openclaw/site-auditor

SEO Crawler by OpenClaw

For SEO-focused auditing, seo-crawler analyzes your site structure, internal linking, heading hierarchy, canonical tags, and schema markup. It produces actionable recommendations prioritized by impact. Pair it with the search skills to also monitor your rankings.

/learn @openclaw/seo-crawler

Content Monitoring

Page Monitor by Majiayu000

The page-monitor skill watches web pages for changes. It tracks price changes, stock availability, content updates, and new listings. Your agent can check monitored pages on a schedule and alert you when something changes. Useful for competitor monitoring, price tracking, and news watching.
