Deadsniper

Dead link (broken link) means a web page you have previously linked to is no longer available. These dead links have a negative impact on SEO, Security and user experience. This tool, inspired by DeadFinder, makes it easy to hunt them down.

Note that this tool is much more limited in scope, only allowing use with a sitemap and only checking http/https links. For customization and a slower, but broader tool, use DeadFinder.

Usage

Usage: deadsniper [options] <link to sitemap.xml>

Options:
  -h | --help    print this help text
  -V | --version print the version number
  -s | --strict  allow only HTTP 200 response codes
  -t | --timeout set the request timeout in seconds (default 5)

Examples:
  deadsniper https://port19.xyz/sitemap.xml
  deadsniper -V
  deadsniper --strict https://port19.xyz/sitemap.xml
  deadsniper -t 1 -s https://port19.xyz/sitemap.xml

Usage via Github Actions

I recommend you download and run the binary, as building a whole docker container slows things down drastically

steps:
- name: Run Deadsniper
  run: |
    wget -q "https://github.com/port19x/deadsniper/releases/download/v1.4/deadsniper" && chmod +x ./deadsniper && ./deadsniper https://port19.xyz/sitemap.xml

Alternatively, you can use the classical github actions approach at a 10-20s speed cost

steps:
- name: Run Deadsniper
  uses: port19x/deadsniper@master
  with:
    sitemap: "https://port19.xyz/sitemap.xml"
