About

Monitor websites for content changes and get Slack alerts only when something real updates.

Most monitoring tools fail on JavaScript-rendered pages or get blocked by anti-bot. This template uses Bright Data Web Unlocker to scrape any URL, Claude AI to detect visible content changes (ignoring timestamps, build IDs, and HTML noise), and Airtable to store the URL list and history.

What you need:

Airtable account (the template includes the base structure)
Bright Data account with Web Unlocker zone
Anthropic API key (Claude)
Slack workspace

How it works:

Pulls active URLs from your Airtable base
Scrapes each page with Bright Data Web Unlocker
Compares the new HTML to the last stored version
If different, Claude summarizes what changed in plain English
Airtable stores the new snapshot, timestamp, and change summary
Slack alerts only on real content changes (skips first runs and structural noise)

Use cases:

Track competitor pricing pages
Monitor product launches and feature updates
Watch regulatory or policy pages
Detect copy or messaging changes on key sites
Track job postings or product availability

Why Bright Data Web Unlocker: Handles JavaScript rendering, CAPTCHAs, and anti-bot challenges in a single API call. Works on sites where Visualping, Distill, and other monitors fail.

Recommended schedule: every 24 hours.
