Bookmark Rot - Broken Bookmarks Checker

Bookmark Rot finds the decay in your bookmark tree and cleans it with an undo for every deletion. WHAT ONE SCAN FINDS - Duplicate bookmarks: the same page saved more than once, matched after tracking parameters are stripped. The oldest copy is kept and the newer copies are pre-selected for removal. - Exact twins: same title and same address saved twice. - Empty folders, including folders that only contain other empty folders. - Near-duplicate folders whose links mostly overlap, with a one-click merge into the first folder (Pro). - Never opened: bookmarks with no visit in your browsing history on or after the day they were saved (Pro, uses the history permission, about 90 days of history). - Link health: every saved link checked and sorted into Dead, Alive, or Unverified (Pro, requires the optional all-sites permission). THREE-WAY VERDICTS, NO GUESSING A link is Dead only when its server answers 404 or 410. It is Alive on a healthy 2xx response. Everything else (blocked, rate-limited, timed out, unreachable, parked, or a DNS failure) lands in Unverified, and nothing in Unverified is ever offered for deletion. EVERY DELETION HAS AN UNDO Each clean is recorded first (title, address, folder, position) in a local restore archive. One click brings a batch back. Chrome does not let extensions restore the original bookmark ID or its original date added, so restore recreates a faithful copy in the same place; the archive view says so in plain words. KEEP THE DUPLICATES YOU MEAN TO KEEP Add an address to your exceptions once and the scanner never flags it again. WEEKLY RE-AUDIT (PRO) Runs the local checks once a week in the background and shows a count on the toolbar icon. The audit never makes a network call. PERMISSIONS, STATED PLAINLY At install: bookmarks, storage, alarms, history. No access to any website. The dead-link sweep asks for all-sites access separately, in a Chrome permission prompt, only when you turn it on. You can revoke it from Chrome's extension settings at any time. When it runs, the extension sends an HTTP request to each bookmarked address and reads the status code plus a small first-bytes sample to detect parked pages. Nothing is sent anywhere else. PRIVACY No account, no analytics, no tracking, no remote code. Settings, the restore archive, exceptions, the license record, and the on-device usage counters stay in your browser's local extension storage. Bookmarks and history are read on your device and never uploaded. FREE AND PRO Free, no account: all Tier 0 checks (duplicates, twins, empty folders), 25 cleans a day, the restore archive, and exceptions. Pro, one payment of $99 (never a subscription): unlimited cleans, the dead-link sweep, never-opened analysis, near-duplicate folder merge, and the weekly re-audit. 14-day refund.
