Know the instant a page changes

Set ScreenshotInk to capture a page on a schedule — daily or hourly — and it compares each new capture against the last one, pixel for pixel. When something changes beyond a threshold you set, it flags the difference and can alert you by email, with the changed regions highlighted. You stop finding out about a broken client page from the client.

What it's for

Client site QA

Catch a layout break, a missing hero, or a defaced page before anyone else notices.

Competitor & price tracking

Watch a competitor's pricing or landing page and get told when they move.

Compliance & content

Keep a dated visual archive proving exactly how a page looked over time.

Deploy verification

Confirm a release changed only what it should, by diffing before and after.

How the diff works

Each monitored page builds a visual timeline you can scroll back through. The comparison is a true pixel diff with an adjustable sensitivity, so minor noise (a rotating testimonial, a timestamp) won't spam you, but a real structural change will. Pages that fail to load are flagged too — so monitoring doubles as a lightweight visual uptime check.

From tool to API and agents

Monitoring runs on the same capture engine as the rest of ScreenshotInk, and the comparison is available on demand through the compare_screenshots API and the MCP server — so an AI agent can diff staging against production in a single step.
