Website Change Monitor with OpenCode

Most of what this agent does on somebody else's site is defined by what it refuses to do: no forms, no sign ups, no clicking into a checkout, no crawling past the address it was handed. Those limits live in the instructions rather than in the harness, so an open general purpose agent like OpenCode holds them exactly as well as a heavier one. What you tune is the churn list, and that decides how often it stays silent.

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.

What you'll need

Set up in minutes

Using this template drops you into a guided setup. It asks exactly this, nothing else:

  1. Connect Firecrawl

    One sign-in. The agent acts through your account, scoped to what this template uses.

  2. Connect Slack

    One sign-in. The agent acts through your account, scoped to what this template uses.

  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 OpenCode

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

  5. Watch it handle a test run

    A staged conversation against a simulated world — then it’s live.

A considered pairing

Why OpenCode for this agent

A reader, never a visitor

One public address is fetched, the way a browser would fetch it. Nothing signs in, nothing submits, and the rest of the domain is left alone.

Churn named once, gone after

Rotating testimonials, build hashes and a copyright year get described once in your notes and stop arriving. That paragraph decides whether the channel is still worth reading in week three.

Good to know

Before you fork

Is there any risk of it triggering something on a site we watch?

The wired operations read a monitor, read its check history and scrape a page, and none of them submit anything. A page behind a cookie wall or an account is reported as unreadable rather than worked around. If you need to watch something visible only after signing in, this template is not the tool for it.
