SignalWatch

Website change and downtime monitor with instant webhooks

Webfreemium

SignalWatch monitors public URLs for content changes or downtime and sends a webhook the moment a page drifts or fails, aimed at operators tracking competitor pricing, status pages, or changelogs without building their own crawler. It includes a dashboard and REST API, with a free tier covering a few monitors at 15-minute intervals.
