Briefpanel

Briefpanel is website change monitoring for teams that watch competitor, supplier or market pages. You paste a URL and describe what matters, and it identifies the items on the page, such as products, plans, jobs or listings, and re-checks them on a schedule. Each change is recorded as added, modified or removed, with the old and new value of the field that moved. Alerts go to email, push, Slack or Discord, and a REST API and MCP expose the same data. Pricing is pay per page read with no subscription.
