The Wayback Machine is a free tool that’s been quietly archiving the entire internet. By simply entering a URL, users can travel back to see exactly how a website looked on a specific date in the past, even if the site has since been deleted or significantly altered. This makes it an essential tool to recover lost information or verify the historical context of online content. For example, see the archived front page of this website.
Similar to Wayback Machine, archive.today is another archive which stores snapshots of web pages and allows you to retrieve them.
