Why it exists

Link checkers either cost a crawler license or turn into a trial after three runs. This one stays in the browser, highlights the problem on the page, and is free.

English site: abl-search.com. Russian site: abl-search.ru. Same product, two domains.

What we will not market

Features that are not in the extension. Google Docs and Sheets support used to be on that list — it shipped, so this page changed too. If something else is missing, the page will change again, not before.
