AI makes updating your site easy. Knowing what changed is harder.

Something changed that you didn't expect

A link disappeared. A section shifted. A page looks different from what you intended.

Something didn't change that you asked for

You gave a clear instruction. It looked done. Then you open the page and realize the change is incomplete, or only applied in one place.

The code looks right. The page might not.

Your assistant shows you the lines it changed, not how every page looks now. A small edit to a shared component can change pages you never opened.

How it works

See what changed after every AI update.

  1. Capture your baseline

    Enter your URL. Sitepager captures your site so you can see what changes after your next update.

  2. Make your changes

    Your team, agency, or AI agent makes the change. Keep working the way you do.

  3. Run Sitepager again

    Set it up once to run automatically, or run it yourself after every update. Get notified by email or Slack (early access) when results are ready.

  4. Review what changed

    See what's new since your baseline. Review the changes and new issues that need attention.

    Repeat after every website update →

  1. Fix the broken link from the latest Sitepager scan of staging.

  2. Reading Sitepager results… Read Sitepager results

  3. Found it. One broken page:

    /others/changelog returned 404.
    Linked from /about · “More AI models | Read more”

    The changelog page is at /other/changelog, so this looks like a typo.

  4. That’s a one-line change on /about. Want me to make it?

  5. Yes, then publish to staging and check again.

  6. Updating the link on /about…

    Done. The link on /about now points to /other/changelog. Publishing to staging now.

  7. Publishing…Published to staging

  8. Running the Entropy Staging scan… Entropy Staging scan complete

  9. All clear. The broken link on /about is fixed.

How we use Sitepager on our own site

“Our site runs on Astro and I make most changes with AI. I stopped clicking through pages after every update. Each deploy starts a Sitepager scan, and I just review what changed.”
