Most uptime monitors just say down. Alertum runs dual-region (EU+US) checks and deterministically classifies every failure — DNS failure, cert expired, TLS error, connection refused, assertion failed — with confidence scores and real evidence, not guesses. It also bundles synthetic journeys, heartbeats, on-call scheduling/escalation, and status pages in one product, skipping the Checkly + PagerDuty + Statuspage stack. Free tier included; paid plans start at €7.99/mo.
