Website Monitoring & Visual Change Detection

Create a monitor with a URL and a frequency. ANEARST captures a baseline immediately, then checks the page on the schedule and stores the visual difference. Email alerts fire on change, failure, and recovery when Resend or SMTP is configured. HTTPS webhooks use HMAC signatures.

Scheduled checks, baseline, and visual diffs run on this server.

Email me when a change, failure, or recovery is detected. Delivery needs SMTP or Resend; the change is always stored.

Scheduled checks run automatically. Failed captures do not consume credits. Register an HTTPS webhook in the workspace to receive the same events.
