About edithistory.wiki
edithistory.wiki is a free tool that presents Wikipedia revision metadata with clear coverage limits. Enter an article title to inspect a retrieved revision window, compare source revisions, and follow links to Wikipedia's own history interface for the complete record.
Why Wikipedia edit history matters
Wikipedia is one of the most-read websites on earth, yet most readers never look past the article they landed on. The edit history — a complete log of every change ever made — is one of the most useful records for checking how visible wording, links, citations, and structure changed over time.
Contributor names, timestamps, and edit summaries are evidence about recorded activity. They are not evidence of an editor's authority, an article's accuracy, or the reason a change occurred.
Journalists, researchers, educators, and curious readers can use edit history to verify what changed in a particular comparison. The source history, talk page, and cited materials provide the additional context needed for broader conclusions.
How it works
When you search for an article, edithistory.wiki queries the Wikipedia MediaWiki API in real time. We fetch up to 500 of the most recent revisions for the article and process them to compute:
- A retrieved revision window with timestamps, contributors, and edit summaries
- Activity counts derived from that window
- A direct source comparison and copyable citation when usable revision IDs are available
- Explicit coverage and provenance information
Results are cached in our database for a short period to keep the site fast and reduce unnecessary load on Wikipedia's servers. All underlying data comes directly from Wikipedia and is publicly available under the Creative Commons Attribution-ShareAlike 4.0 license.
Who built this
edithistory.wiki is an independent project built by a small team of developers who believe that Wikipedia's revision data deserves a better interface. It is not affiliated with the Wikimedia Foundation in any way. We built it because we kept wanting to check edit histories ourselves and found Wikipedia's built-in history pages too cumbersome for quick analysis.
The site is free to use. We keep it running through non-intrusive display advertising. If you have feedback or suggestions, we'd love to hear from you.
