katana Command Examples

A fast crawler focused on execution in automation pipelines offering both headless and non-headless crawling. See also: gau, scrapy, waymore. More information: https://github.com/projectdiscovery/katana.

• Crawl a list of URLs:

katana -list {{https://example.com,https://google.com,...}}

• Crawl a [u]RL using headless mode using Chromium:

katana -u {{https://example.com}} {{[-hl|-headless]}}

• Use subfinder to find subdomains, and then use [p]a[s]sive sources (Wayback Machine, Common Crawl, and AlienVault) for URL discovery:

subfinder {{[-dL|-list]}} {{path/to/domains.txt}} | katana -passive

• Pass requests through a proxy (http/socks5) and use custom headers from a file:

katana -proxy {{http://127.0.0.1:8080}} {{[-H|-headers]}} {{path/to/headers.txt}} -u {{https://example.com}}

• Specify the crawling strategy, depth of subdirectories to crawl, and rate limiting (requests per second):

katana {{[-s|-strategy]}} {{depth-first|breadth-first}} {{[-d|-depth]}} {{value}} {{[-rl|-rate-limit]}} {{value}} -u {{https://example.com}}

• Find subdomains using subfinder, crawl each for a maximum number of seconds, and write results to an output file:

subfinder {{[-dL|-list]}} {{path/to/domains.txt}} | katana {{[-ct|-crawl-duration]}} {{value}} {{[-o|-output]}} {{path/to/output.txt}}
