What is it?
Muffet is a command-line website link checker. Given a starting URL, it crawls the site recursively, scrapes each page, and inspects the links and resources it references so that broken targets can be found before visitors hit them.
It checks multiple HTML tags, including anchors, images, link elements and scripts, and aims for high compatibility with how web browsers interpret pages. Results can be printed as plain text, JSON, or JUnit XML, which makes the tool usable both interactively and in automated pipelines.
Muffet can be installed with the Go toolchain and also run through Docker or as a GitHub Action, according to its project documentation.
