Catfish: Open Source Web Scraper & Website Accountability Tool
Detect duplicate content, find scraped websites, and identify online identity theft with Catfish, an open source web scraper and website accountability tool.
What is Catfish?
Catfish is a free, open source web scraping and website accountability tool. It allows users to enter a website URL and Catfish will search across the internet to find scraped, duplicated, or otherwise copied content from that site. It works by comparing the entered website against its databases of crawled sites from across the web.
Some key features and uses of Catfish include:
- Detecting website scraping or copying - Enter your own site and find who has stolen or copied your content without permission.
- Finding cases of online identity theft - Enter personal sites/pages and see who may be impersonating you online.
- Uncovering copyright infringements - Provide proof of scraped or illegally shared copyrighted material from your sites.
- Backlink checking - See all over the web that is linking to or has referenced your website or content.
- Researching domain history - Enter a domain to discover what sites it previously redirected to or hosted.
Catfish works by comparing the HTML, CSS, JS, and image files of the entered website against its databases of crawled websites. It looks for matching code, text, links, visual similarity, and other signals to uncover potential scrapes or copies. The tool provides a report of the top matching sites found, allowing further investigation. It provides both free and paid plans to suit different user needs.
