Shows its work
Every dead link comes with its reason: HTTP 404, Host not found, Timeout. No black-box score, no guessing why.
Lookmark for Mac
Years of Safari bookmarks quietly rot: sites shut down, pages move, domains lapse. Lookmark checks every one, shows you what broke and why, and helps you rescue or set aside the dead ones. It never deletes a thing.
For Safari on macOS 13 Ventura or later
Every bookmark, checked
Lookmark visits each bookmark, a dozen at a time, and listens to what comes back. A domain that no longer exists is dead. A page that says "not found" is dead. A site that's busy for a minute is not. You choose how strict to be.
Dead only on 404 / 410. Everything else reachable = alive.
Look before you leap
A status code doesn't tell the whole story. Click any dead link and Lookmark opens it right beside the list, so you can tell an honest error page from a domain parked by squatters, or from a site that turns out to be fine.
Rescue from the archive
The Internet Archive's Wayback Machine has been saving the web since 1996. Turn on archive.org restore, and when you select a dead link Lookmark looks up its closest snapshot. If there is one, check Restore and your bookmark points at the saved copy instead, right where it always was.

Your bookmarks are years of your life, so Lookmark treats them that way. Dead links aren't thrown out; they're moved into a Dead Links folder in Safari, where you can look them over and delete them yourself, whenever you like.
Why Lookmark
Lookmark is a small, single-purpose Mac app. It does one job, shows its work, and leaves the final say to you.
Every dead link comes with its reason: HTTP 404, Host not found, Timeout. No black-box score, no guessing why.
Strictness, timeout, which links to move and which to rescue: all yours. Lookmark suggests. It never cleans up behind your back.
No account, no analytics, no typif.ai servers. Lookmark only contacts the sites you bookmarked, plus archive.org when you ask it to.
Coming soon for Mac
Lookmark is almost ready. A native Mac app for Safari's bookmarks, on macOS 13 Ventura or later.
