Description
Detects HTTP errors (404, 4xx, 5xx, CORS) and shows a recovery overlay with Wayback Machine, Google search, and domain diagnostics. Every broken link is a dead end — until now. 404Found automatically detects when a page fails to load and overlays a clean recovery panel directly on the broken page. No new tabs, no copy-pasting URLs, no manual searching. Just instant options to get you where you were trying to go. What it does The moment you hit an error, 404Found analyses it and shows you the best path forward: 🗄 Wayback Machine — Instantly checks the Internet Archive for the last saved version of the page. If it was ever crawled, you can read it in one click. 🔍 Smart Google Search — Parses the broken URL into readable search terms and pre-builds a Google query so you can find the content that moved. 🏠 Homepage shortcut — One click back to the site's root, so you can navigate from a working starting point. 🌐 Domain health check — Tells you whether the whole site is gone or just this specific page, so you know whether to keep looking. 🔴 Server error recovery — For 500, 502, 503 and 504 errors, it checks whether the site is down for everyone, surfaces the official status page, and lets you reload with a single click. 🔒 Access error guidance — For 401 and 403 pages, it checks whether a public archived version exists so you can still read the content. Why install it Broken pages are invisible speed bumps in your workflow. 404Found turns a frustrating dead end into a five-second recovery. Whether you're a developer chasing down broken links, a researcher following old citations, or just someone who clicked a link that no longer works — 404Found gives you back the content you were looking for. Entirely private. No accounts, no servers, no tracking. Everything runs locally in your browser.
