UptimeMonke: Uptime Monitor

UptimeMonke watches your websites and APIs around the clock and tells you the moment something breaks — before your customers do. Sub-minute checks. Multi-channel alerts. No subscriptions. WHY UPTIMEMONKE DOWN BEFORE YOUR USERS NOTICE Continuous HTTP, SSL, TCP, DNS and ICMP checks run on a global edge fleet. When a monitor fails, alerts go out immediately over the channels your team already lives in — Slack, Discord, custom webhooks and email. EVERY CHECK TYPE, OUT OF THE BOX • HTTP(S) and API monitors with keyword and status-code assertions • SSL certificate expiry warnings at 30, 14 and 7 days • TCP port and DNS record monitoring • ICMP ping • Cron heartbeats — get alerted when a scheduled job stops calling home INSTANT, DEPENDABLE ALERTS Notifications land in Slack, Discord, custom webhooks and email. Alert contacts are verified before they can receive anything, so nobody can spoof a channel and page your team. BRANDED PUBLIC STATUS PAGES Publish a clean status page with 90-day uptime history and a live incident feed. Keep customers informed during an outage instead of answering support tickets. BUILT FOR DEVELOPERS • Response-time and latency charts across 24h, 7d, 30d and 90-day windows • Full incident log with resolved outages and their causes • Cross-region confirmation guards against false alarms • Hardened against SSRF and cloud metadata attacks — safe even for internal targets FREE, FOREVER Every feature works on a free account: all check types, sub-minute intervals, public status pages and alerting. There is no paid plan. An optional one-off donation buys extra check capacity for heavier workloads — and running out never stops your monitoring. Install UptimeMonke and know the second your site goes down.
