PulseWatch tracks third-party vendor and cloud outages and checks your own sites for reachability, latency, TLS grade and domain expiry. It has a web dashboard and a REST API, with a live incident feed. Alerts go to email, in-app, webhook, Slack, Teams, Discord, PagerDuty, Opsgenie, ServiceNow or Datadog.
The free forever plan needs no credit card and includes 1 watchlist, up to 5 vendors, 3 own sites, 3 in-app and email alert rules and 30 days of incident history. Pro is $49/month and Business is $149/month, and Enterprise is by contacting sales. The site says it is not affiliated with the services it monitors, and its footer notes the detection engine is under replay review.
PulseWatch was built after the builder spent client incidents checking vendor outages across too many separate pages.
