🔍 AppDiff
📣 What this app will do for you
This app will take two captures of the same page, before and after an update and turn it into a side-by-side list of what changed. It's your Compare a site before & after an update — built for exactly that job.
Compare a website before and after an update — step by step, from snapshots you supply yourself. Define a journey (sign-in, purchase, lesson completion, file download, or any steps you name), record a baseline you have reviewed, then compare new snapshots against it and see exactly what text appeared, disappeared, or changed, and whether any step's status changed.

What AppDiff is — and is not
- It is a before/after comparison for your own site: named journey steps with expected visible text, reviewed baseline snapshots (URL + visible text + status), and comparison reports showing added lines, removed lines, unchanged lines, status changes, and whether each step's expected text is still present.
- It is not a scanner, crawler, or monitor. It never fetches a live site, never logs in, never stores credentials, and never bypasses a site's protections. Use it only on sites you own or have permission to test.
- It does not parse binary documents (paste the text instead), guess which new line replaces which old line, or catch changes missing from the snapshots you supplied.
- Baselines are only trusted after you review them. A baseline you have not confirmed cannot be compared against, and editing one resets its confirmation.
