The new snapshot is saved back to your CRM\n6. If a real change is detected, **Slack** notifies your team\n\n## Why Bright Data?\n\n- Bypasses CAPTCHAs, bot detection and geo-blocks\n- Renders JS-heavy pages (SPAs, dynamic content)\n- Reliable for daily monitoring at scale\n\n## Prerequisites\n\n- A [Bright Data](https://brightdata.com) account with a Web Unlocker zone\n- An [Anthropic](https://anthropic.com) API key (any Claude model works)\n- A CRM/DB to store URLs and snapshots (Airtable shown by default)\n- A [Slack](https://slack.com) workspace and channel\n\n## Setup (~10 min)\n\n1. Connect Airtable, Bright Data, Anthropic and Slack credentials\n2. Set the Schedule Trigger interval (hourly, daily\u2026)\n3. Add URLs to your CRM with `Active = TRUE`\n4. Activate the workflow"
