Wayback Delta Analyzer
Websites change constantly — content is removed, contacts disappear, links break. The Wayback Delta Analyzer captures the current state of any page and compares it against the most recent Wayback Machine archive, surfacing everything that changed.
OSINT Applications
Deleted contact information, removed employee pages, changed company descriptions, and broken links all provide intelligence. Content removal often indicates something the organization wants to hide.
- CDX API
- The Wayback Machine's index API that returns a list of all archived snapshots for a given URL.
📜 Wayback Delta Analyzer — FAQ
How far back does it compare?
It fetches up to 20 snapshots from the Wayback Machine and compares the live page against the most recent archive. The timeline shows all available snapshots.
Why are some links shown as removed/added?
Links are compared by exact URL. Minor changes (trailing slashes, parameter order) will appear as removals/additions even if the destination is the same.
Does it work on JavaScript-rendered pages?
The live page capture reads the rendered DOM. The archived version depends on what the Wayback Machine captured — it may not include JS-rendered content.
Can I compare two specific archive dates?
Currently it compares live vs most recent archive. Multi-snapshot comparison is planned for a future update.
What if the page has never been archived?
The tool will report no snapshots found. Consider triggering an archive.today snapshot first for future comparisons.
