The Internet Archive presents The Official Wayback Machine Extension. With the power of the Wayback Machine, you can go back in time to see how a website has changed and evolved through the history of the Web!

Functions include seeing the oldest or newest version of a website, or a calendar of every past archive. There's also the "Site Map" feature that will draw a pie graph of the past history of pages of a site.

The toolbar button shows you how many snapshots of the website you're visiting are in the Wayback Machine, and the date of the latest snapshot in the popup window.

You can right-click, then "Open in Wayback Machine" in the context menu. Try it while over a link.

Whenever you encounter a "dead link" (a.k.a 404 Not Found) page, this extension will automatically provide a link to a saved version in the Wayback Machine.

Most features work without requiring an account, but if you do create an account, you'll be able to archive any website easily with just a single tap of a button.

Convenient 3rd-party functions for searching for Related Tweets, Alexa, and Whois for looking up domain names, as well as sharing links on social media websites.

It's a Safari extension to access

As the blurb explains nothing, here’s what this does:

For years I've kept a bookmark of a bit of Javascript that takes the current URL and opens it in the Wayback Machine at This will show the archives that they’ve saved of that specific web page, which can be a lifesaver. E.g. I've downloaded installers from shareware I've bought from a developer that’s gone out of business and no longer has a download page. Or you can just look at what looked like in 1996.

This Wayback Machine app installs a Safari extension that gives you a little button with several more options, like directly see the most recent version archived, the first version archived, or to tell them to take a snapshot of that page right now.

The disadvantage is that it wants an login, which 1Password informs me I made for some reason 10 years ago, so I guess that worked out well in my case.

The UI response could use a bit more snappiness, but once you click a button it seems to be doing its stuff in the background and will eventually open the page for you.

I'll keep the Javascript bookmark around, but this is nice to have in Safari as well.

This Safari extension is incredibly useful, and honestly makes browsing the web pretty fun. You could probably imagine it allows you to quickly view older snapshots of websites, but one of the features I really love is being able to quickly archive any website. There's a little red number above the icon that will tell you how many times the site has been archived, and if you click it, it'll tell you the last time it was archived. I love this feature, because now whenever I find a website that either isn't archived at all or hasn't been in a long time, I just archive it! Makes me feel a little more accomplished even if all I'm doing is using the Internet like a lazy bum. I personally haven't experienced any of the issues the other reviewers are mentioning - maybe they've been patched, or maybe I'm just lucky. All in all, this extension is useful and fun, so I reccomend it.

So glad that it has an Safari version extension!

I used it on Chrome a lot, but recently I prefer safari more and I happen to find this extension available on App Store. What a great tool!
