1. Open the vendors section
In the dashboard, go to Monitoring and find the Vendors section. The watchlist is a flat-rate add-on ($11.99/mo, $119.90/yr) on top of any paid Monitor plan (Growth or Scale); an account without it, on any tier including Free, sees an upgrade plate explaining the flat price rather than a truncated list.
2. Add the services you depend on
Search the catalog and add each vendor you rely on. With the add-on held, the account can watch up to 100, stated plainly as an internal fairness cap on probe capacity rather than a per-vendor charge: the price is the same flat rate whether you watch one vendor or the full cap. Each tile shows RealUptime's own live probe reading for that vendor and, when we have one, the vendor's own status-page claim shown separately and never merged into our reading.
3. Pick where the alert goes
Alerts route through your account's normal alert rule: email, Slack, a registered webhook endpoint, or the notification channel registry (Discord, Teams, Opsgenie, Zapier). No separate setup: the same channels that page you for your own monitors carry vendor alerts.
4. Know what triggers an alert
Only a probe-confirmed measured event: when our own probes open, reopen, or close an outage on a watched service, from named regions, at a named time. A user report, a social-media spike, or the vendor's own status-page claim never opens an alert on its own: that is exactly the never-falsify rule the rest of RealUptime Outages holds to.
