Last Update Checker is a free Chrome add-on developed by Anton Pernisch. This handy tool scans websites and all their resources to find out exactly when a page was last updated, down to the second. Whether you're a professional who needs the most current information or simply curious about the timeliness of an article, Last Update Checker has you covered.

In its current alpha state of development, Last Update Checker scans the OpenGraph protocol within a website's code. This means it can provide you with the most recent update information available. Although it is still a work in progress, the extension promises additional functionalities in the future.

If you find this tool useful and want to support its development, there is a tip jar available through Anton Pernisch's PayPal account.
