Website Change Monitor with Claude Code

A check only tells you a page is no longer identical to last time, and the flagged difference is a pointer rather than an account of what happened. The job is to open the live page and read it properly first, because a note written off the comparison alone gets the direction of a change backwards often enough to matter. Reading the source thoroughly before making a claim is the habit Claude Code brings.

Live demo

Watch it work before it's live

Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

Northwind Analytics pricing

Firecrawl monitorhttps://northwindanalytics.com/pricing

The 07:15 check flags the pricing page. The Team tier has gone from 29 euro per seat per month to 39, the words starting at have been deleted from the Business tier, and a row reading unlimited connectors is missing from the comparison table. This address last changed 41 days ago.

  3. Watch pages

    Every address you are watching and what a real change looks like on each: which are pricing, docs or changelogs, what you want called out on each one, and the churn you already know about and want ignored.

  4. Runs on Claude Code

    Preselected for this page — connect your Claude Code account during setup, or switch to NoClick's built-in models with one click.

A considered pairing

Why Claude Code for this agent

The check points, the page tells

The current text is the evidence. Fetching and reading before summarising is what keeps a price rise from being reported to your sales team as a price cut.

History decides the weight

Recent checks on the same address are pulled first, so a page that has been still for six weeks reads very differently from one that shifts every night.

Good to know

Before you fork

How do we see what a note looks like before Slack does?

A Test Run produces a finished note from a staged check: a seat price moving, a page full of cosmetic churn, a vendor deprecation banner. You can read all three and adjust your watched pages notes before a real check ever fires. Nothing in a rehearsal reaches the sites you watch.
