FAQ
How is link reachability judged and how accurate is it?
Due to CORS the browser cannot read cross-domain status codes. Probes use fetch in no-cors mode: an opaque response means reachable, an error or 8 second timeout means unreachable. Exact codes stay unknown, so verify before deleting.
Which links are skipped without a probe?
Links that are not http or https, such as javascript links, in-page anchors and empty links, are skipped. Checking runs 6 at a time with an 8 second timeout per link, so keep the page open until it finishes.
