FireCrawl
FireCrawl crawls and convert any website into LLM-ready data. It crawls all accessible subpages and give you clean markdown and metadata for each. No sitemap required.
FireCrawl handles complex tasks such as reverse proxies, caching, rate limits, and content blocked by JavaScript. Built by the mendable.ai team.

Scrape, crawl and extract the web with a single API. Ideal for AI companies looking to empower their LLM applications with web data.\n\nWhat sites work?\n\nFirecrawl is best suited for business websites, docs and help centers. We currently don\'t support social media platforms.\n\nWho can benefit from using Firecrawl?\n\nFirecrawl is tailored for LLM engineers, data scientists, AI researchers, and developers looking to harness web data for training machine learning models, market research, content aggregation, and more. It simplifies the data preparation process, allowing professionals to focus on insights and model development.\n\nIs Firecrawl open-source?\n\nYes, it is. You can check out the repository on GitHub. Keep in mind that this repository is currently in its early stages of development. We are in the process of merging custom modules into this mono repository.\n\n#### Scraping & Crawling\n\nHow does Firecrawl handle dynamic content on websites?\n\nUnlike traditional web scrapers, Firecrawl is equipped to handle dynamic content rendered with JavaScript. It ensures comprehensive data collection from all accessible subpages, making it a reliable tool for scraping websites that rely heavily on JS for content delivery.\n\nWhy is it not crawling all the pages?\n\nThere are a few reasons why Firecrawl may not be able to crawl all the pages of a website. Some common reasons include rate limiting, and anti-scraping mechanisms, disallowing the crawler from accessing certain pages. If you\'re experiencing issues with the crawler, please reach out to our support team at hello@firecrawl.com.\n\nCan Firecrawl crawl websites without a sitemap?\n\nYes, Firecrawl can access and crawl all accessible subpages of a website, even in the absence of a sitemap. This feature enables users to gather data from a wide array of web sources with minimal setup.\n\nWhat formats can Firecrawl convert web data into?\n\nFirecrawl specializes in converting web data into clean, well-formatted markdown. This format is particularly suited for LLM applications, offering a structured yet flexible way to represent web content.\n\nHow does Firecrawl ensure the cleanliness of the data?\n\nFirecrawl employs advanced algorithms to clean and structure the scraped data, removing unnecessary elements and formatting the content into readable markdown. This process ensures that the data is ready for use in LLM applications without further preprocessing.\n\nIs Firecrawl suitable for large-scale data scraping projects?\n\nAbsolutely. Firecrawl offers various pricing plans, including a Scale plan that supports scraping of millions of pages. With features like caching and scheduled syncs, it\'s designed to efficiently handle large-scale data scraping and continuous updates, making it ideal for enterprises and large projects.\n\nDoes it respect robots.txt?\n\nYes, Firecrawl crawler respects the rules set in a website\'s robots.txt file. If you notice any issues with the way Firecrawl interacts with your website, you can adjust the robots.txt file to control the crawler\'s behavior. Firecrawl user agent name is \'FirecrawlAgent\'. If you notice any behavior that is not expected, please let us know at hello@firecrawl.com.\n\nWhat measures does Firecrawl take to handle web scraping challenges like rate limits and caching?\n\nFirecrawl is built to navigate common web scraping challenges, including reverse proxies, rate limits, and caching. It smartly manages requests and employs caching techniques to minimize bandwidth usage and avoid triggering anti-scraping mechanisms, ensuring reliable data collection.\n\nDoes Firecrawl handle captcha or authentication?\n\nFirecrawl avoids captcha by using stealth proxyies. When it encounters captcha, it attempts to solve it automatically, but this is not always possible. We are working to add support for more captcha solving methods. Firecrawl can handle authentication by providing auth headers to the API.\n\n#### API Related\n\nWhere can I find my API key?\n\nClick on the dashboard button on the top navigation menu when logged in and you will find your API key in the main screen and under API Keys.\n\n#### Billing\n\nIs Firecrawl free?\n\nFirecrawl is free for the first 500 scraped pages (500 free credits). After that, you can upgrade to our Standard or Scale plans for more credits.\n\nIs there a pay per use plan instead of monthly?\n\nNo we do not currently offer a pay per use plan, instead you can upgrade to our Standard or Growth plans for more credits and higher rate limits.\n\nHow many credit does scraping, crawling, and extraction cost?\n\nScraping costs 1 credit per page. Crawling costs 1 credit per page.\n\nDo you charge for failed requests (scrape, crawl, extract)?\n\nWe do not charge for any failed requests (scrape, crawl, extract). Please contact support at help@firecrawl.dev if you have any questions.\n\nWhat payment methods do you accept?\n\nWe accept payments through Stripe which accepts most major credit cards, debit cards, and PayPal.\n\n[🔥](/)\n\n© A product by Mendable.ai - All rights reserved.\n\n[StatusStatus](https://firecrawl.betteruptime.com)\n[Terms of ServiceTerms of Service](/terms-of-service)\n[Privacy PolicyPrivacy Policy](/privacy-policy)\n\n[Twitter](https://twitter.com/mendableai)\n[GitHub](https://github.com/mendableai)\n[Discord](https://discord.gg/gSmWdAkdwd)\n\n###### Helpful Links\n\n* [Status](https://firecrawl.betteruptime.com/)\n \n* [Pricing](/pricing)\n \n* [Blog](https://www.firecrawl.dev/blog)\n \n* [Docs](https://docs.firecrawl.dev)\n \n\nBacked by\n\n\n\n###### Resources\n\n* [Community](#0)\n \n* [Terms of service](#0)\n \n* [Collaboration features](#0)\n \n\n###### Legals\n\n* [Refund policy](#0)\n \n* [Terms & Conditions](#0)\n \n* [Privacy policy](#0)\n \n* [Brand Kit](#0)')
