# WebURLTracker

> Website change monitoring with visual and text diffs, region targeting, and alerts.

WebURLTracker watches a public URL or a signed-in page in Chrome. You pick the region that matters. Later checks store a screenshot and a text diff. Alerts go to email, Slack, Teams, Discord, Telegram, or a webhook.

Do not send private or localhost URLs. Monitor URLs are SSRF-checked. Captures stay in the workspace. Signed-in sessions stay in the Chrome extension.
