Web scraping JavaScript-heavy sites requires a crawler that executes JS rendering and supports CSS or LLM-based extraction. Crawl4AI handles JS execution, multi-URL pipelines, and returns clean Markdown or JSON for downstream tasks.
Batch processing multiple URLs to generate markdown requires configurable crawl pipelines. Crawl4AI supports multi-URL batch crawling with per-session BrowserConfig and per-crawl CrawlerRunConfig, delivering markdown, JSON, links, and media metadata outputs.
Yes, CSS selectors enable deterministic web scraping without relying on LLM-based extraction. Crawl4AI supports CSS-based deterministic extraction alongside optional LLM-based extraction, giving you control over structured data retrieval methods.
Yes, Crawl4AI provides both CLI and Python SDK interfaces for web scraping automation. The CLI handles quick tasks while the Python SDK enables automation for building end-to-end data pipelines, batch processing, and session management.
Configuring browser sessions and crawl settings for batch web scraping uses per-session BrowserConfig and per-crawl CrawlerRunConfig. These settings control JS execution, content filtering, session management, and output delivery of markdown, JSON, and media metadata.
Web scraping returns unstructured content instead of clean markdown when content filtering and markdown generation are not applied. Crawl4AI includes content filtering and markdown generation during crawling to ensure outputs are clean and structured for downstream pipelines.
