When Was This Website Published? is a Chrome extension that lets you find out the publication date of the webpage you are currently browsing. If you've ever read an article or blog post online and wondered when it was published—especially when no date is shown—this tool provides an easy solution. Simply click the extension icon, and it will show you the most accurate estimate of when the website or page was first archived.

This extension leverages the Wayback Machine's extensive web crawl data to gather historical web snapshots. While it strives for accuracy, availability depends on archival records, so results may vary. It's a handy tool for digital researchers, online readers, or anyone curious about a webpage's age.

User reviews

Users appreciate this Chrome extension for accurately finding website publication dates, especially when not readily available, making it invaluable for academic and work-related referencing. It's praised for its simplicity, reliability, and ability to handle older or obscure sites. Suggestions include adding features like displaying the site's age in a more striking way, offering a floating window for easier access, and including last update dates to enhance usability.

Pros

Provides accurate website publication dates even for older or obscure sites.
Extremely useful for academic referencing and work projects.
Simple and easy to use without needing to inspect HTML code or run commands.
Works reliably as promised and saves time.
Helps find publication dates when not provided by the author.

Cons

Lacks display of website age (e.g., 'xx months old') alongside the publication date.
No floating window option to show website age without clicking the extension.
Does not show date of last update, which some users find useful.

Recent reviews

Exactly what i was looking for. Search results are filled with older non relevant articles. Until they find a cure for it this extension will be helpful. But could you add "xx months old" or something along with the actual date. Knowing the exact age would be more striking. Also if there could be an option for floating windows that automatically tells the age of a website without always need to clicking on the extension.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
