history

Project history and usage

Muffet is a website link checker written in Go by raviqqe. The GitHub repository was created in 2018, and the project site describes it as a fast link checker for static websites that recursively scrapes and inspects pages.

Project history

Its technical emphasis is speed and CI-friendly output. The documentation lists support for browser-like link discovery across tags such as `a`, `img`, `link`, and `script`, along with text, JSON, and JUnit XML output. That places Muffet in the same operational niche as broken-link checkers used by documentation sites, static-site projects, and release pipelines: run it against a base URL, fail or inspect output when broken references appear, and integrate the result into GitHub Actions, Docker, or other automation.

How it is used

For package managers, Muffet is a compact developer-tool package: one executable, MIT licensed, installable through Go or Homebrew, useful when a site needs link validation without a larger crawler framework.
