Know which docs screenshots are out of date before your users do.
StaleSnap finds every screenshot in your product documentation, captures the matching screen of your live app on a schedule and flags the ones that no longer match, with a visual diff of what changed.

What StaleSnap does
Every release changes a label, a menu or a layout somewhere. Screenshots in help centers and guides quietly drift out of date, and nobody notices until a customer gets confused. StaleSnap checks them for you.
Finds every screenshot
Point StaleSnap at your public documentation. It crawls the pages and lists every image, and you can ignore diagrams, logos and paths that are not product screenshots.
Maps images to app screens
Link each screenshot to the screen of your app it shows. StaleSnap suggests likely paths and locates the screenshot inside the full screen automatically, even when it was cropped or taken at another zoom.
Captures your live app
A headless browser signs in with a demo account you provide and captures each screen in the same state as your docs: theme, time zone, locale and viewport.
Compares like a reviewer
Block-based structural similarity tolerates compression and anti-aliasing but catches a renamed button or a moved menu. Mark dynamic areas such as dates or charts to ignore them.
Dashboard and email alerts
See stale screenshots side by side with the fresh capture and a highlighted diff, and get an email when a check finds screenshots that went out of date.
Built with security in mind
Demo-account passwords are encrypted at rest and only decrypted for a capture. Captures run in a separate, isolated browser service. Accounts support two-factor authentication.
