FireCrawl is an open-source project developed by Mendable.ai that allows you to crawl all accessible subpages of any website without needing a sitemap. It then converts this content into clean, formatted Markdown documents. It's especially useful for data scientists, machine learning engineers, content creators, and market analysts looking to extract valuable information from website content. FireCrawl can handle content rendered dynamically with JavaScript, offers API services, supports self-hosting, and integrates with various developer tools and frameworks.
