"[T]ools like Versionista are making it easier still to spot alteration over time." -- The Economist

"Beyond the gotcha value, there are other very useful applications for [Versionista]. You can use it to monitor prices on a product page. You can keep an eye on a competitor's site for changes relevant to your business, or for additions to their news page. -- CNET

"John McCain's campaign published a side-by-side comparison of Barack Obama's Iraq War policy web pages on Tuesday using a new automated online tracking service called Versionista." -- Wired

"Versionista helps to promote accountability by giving activists the ability to see when politicians have changed the language of their campaign promises and policy statements." -- ars technica

Versionista monitors Web sites that you specify for edits. Our Web-based service records every change, clearly highlighting added or deleted words and sentences.

You can view multiple generations of edit histories for every page on a site. At the same time, filtering eliminates information overload by tracking only content that matters.

Comprehensive competitive intelligence

Versionista was designed by PhDs for the rough-and-tumble world of today's Web.

  • Every site edit, version, and deletion is "set in stone" by Versionista on an hour-by-hour basis.

  • Precise historical mapping of a Web site's edits, including "scrubbing" of potentially compromising information, is a competitive advantage to journalists, campaigns, corporations, and activists.

  • Versionista gives a "big picture" visualization of the evolution of a site, particularly one that has multiple editors, bloggers, or outside contributors.

How it works

A side-by-side comparison and multiple other views let you see "before and after" versions of every monitored page. We highlight what text has been added, deleted, or moved. Versionista will keep up to 25 versions per page. You can "rollback" in time to see older versions.

Start tracking sites right now

Yep, you can track a few URLs for free, too.

But, to proceed, you must confirm your e-mail address. We will not share your e-mail address with others, and we will send only occasional announcements and interesting (largely political) comparisons -- see our privacy policy.

Another recent Slate.com piece highlighted more changes to candidates’ Web sites caught by Versionista, noting, particularly, edits on Internet privacy on Obama’s Technology page. This latter edit caused quite a bit of stir online, particularly with a Slashdot reference. The Obama campaign responded as noted in this Wired article.

Palin did actually appear at this New Mexico rally. Not sure, then, why reference to her is removed the day after?

Deletions from Pelosi’s Security page and the removal, from whitehouse.gov, of a link to the Hurricane Katrina section both raise questions of timing.

We didn’t realize until now that the McCain site linked to Versionista again. They were highlighting edits to Obama’s Social Security page.

More notably, another use of Versionista by the McCain site garnered some international press. Their highlight of changes to Obama’s Urban Policy page, and the deletion of reference to a Foreclosure Prevention Fund, was mentioned in The Scotsman, The Press and Journal, and The Spectator.

Slate.com published many, many interesting Versionista edits. If you’re interested to see recent edits to the political sites, check the Slate article for notable before-and-after comparisons. (Note that we have a new logo in Slate… you will be seeing it here as soon as we get the new site design in place.)

The Slate piece was used as a basis for this Dutch article. Perhaps related, we also got another mention in CNET.

Will Tom Ridge be McCain’s VP pick? Or maybe not?

In any case, it is certainly peculiar that former Governor Ridge’s name was removed from a McCain PA rally scheduled for this Saturday!
