About SignalWatch
SignalWatch monitors public URLs for content changes and downtime, then delivers a unified text diff by email, Slack, Discord or an HMAC-signed JSON webhook. CSS selector, ignore regex and minimum-change filters cut noise. REST API and dashboard included. Free tier: 3 monitors at 15 minutes; Pro $12/mo; Business $29/mo. Public pages only — no JS rendering or logged-in sessions.
