help LinkChecker FAQ

What does LinkChecker check on a website?

LinkChecker crawls a website and checks internal and external hyperlinks for errors. It can identify broken URLs, redirects, and outdated links, then produce a report for review.

Is LinkChecker a browser extension or a command-line tool?

LinkChecker is an open-source tool available through command-line and web-based use. It is written in Python and is intended for crawling sites recursively rather than checking only the page currently open in a browser.

Can LinkChecker test external links as well as internal links?

Yes, it can verify both internal and external hyperlinks. External sites may limit requests or change their responses, so a reported failure should be reviewed before removing a link.

Does LinkChecker crawl an entire website automatically?

It can crawl recursively from a starting URL, following links according to its configuration. Large sites should be limited with suitable scope and exclusions so the scan does not create unnecessary traffic.
