Hey Product Hunt I built Alertum because every uptime monitor I'd used stopped at "it's down" — you'd get paged at 3am and still have to manually dig through logs to figure out if it was DNS, an expired cert, or your API actually falling over. Alertum runs every check from two independent regions (EU + US) and deterministically classifies each failure — DNS failure, cert expired, TLS error, connection refused, assertion failed, response-time threshold — with a confidence score and the actual evidence (status codes, IPs, timing breakdown). No LLM guessing, just rules applied to real telemetry, so the same failure always gets the same diagnosis. Beyond uptime checks, it's one product instead of a stitched-together stack: Multi-step synthetic journeys (logins, checkouts) with the exact failed step surfaced Heartbeat monitoring for cron jobs and background workers On-call scheduling + escalation policies Public/private status pages 10 notification channels (Slack, Discord, Teams, Telegram, webhooks, and more) An AI assistant that summarizes incidents in plain language Free plan is genuinely usable — 25 monitors, SSL/API/website checks, no credit card required. Would love to hear what you'd want monitored that isn't covered yet, or what's confusing in the first 5 minutes of setup. I'll be in the comments all day.
