Wayback Machine Checker

This checker asks the Internet Archive when a website or page was first saved in the Wayback Machine. It also finds the latest snapshot. If you pick a date, it finds the one closest to that day too, and each comes with a link.

The first archived date is a quick history check. A shop that claims 20 years in business but was first captured last spring deserves a closer look. The same goes for a domain you plan to buy, since old snapshots show what it was used for before. Keep in mind that the archive only holds what its crawlers or visitors chose to save. A gap does not prove a site was offline, and the first capture can come years after a site went live.

Snapshots can also rescue content. If a page you cited has changed or vanished, the capture closest to the day you read it is often still there. Enter the full page URL, not just the domain, to find that exact page. Dates are shown in UTC, the time zone the archive uses.

Your browser sends the URL to the Internet Archive's public availability API. The tool makes two or three small requests: one for the latest capture, one for the earliest and one for your date. Each request returns a single snapshot, so the tool cannot count how many captures exist. The API may skip captures it cannot use and return one further away, and it can be slow or briefly return nothing when the archive is busy. For every capture, open the calendar link under the results. To check what a site sends today, try the Security Headers Checker or the SSL Certificate Checker.
