About muffet

muffet is a command-line tool that starts from a URL, crawls the pages of a website and reports links that fail. It is written in Go and checks links concurrently, which keeps runs on larger sites short.

The repository includes a Dockerfile, so it can run in a container as well as a standalone binary. It suits developers and site maintainers who want broken-link checks in a terminal or as a step in a build pipeline.

Strengths

  • Fast concurrent crawling
  • Fits easily into CI pipelines
  • Can run from a Docker image

Limitations

  • Command line only, no graphical interface
  • Focused on links rather than wider SEO or markup checks
