Katana – Crawling and Spidering Framework

>Katana is a Fast and Customizable Crawling and Spidering Framework by the [ Developers of Nuclei, Subfinder, and HTTPx ] ProjectDiscovery. Katana can crawl multiple domains and subdomains simultaneously. The crawling experience is made better by its crawling modes i.e. Standard and Headless. The level of customization provided by Katana in scope, rate limiting, filters, outputs, and modes is what makes it the best for crawling.
