UPKira

UPKira keeps an eye on your websites, APIs, servers and scheduled jobs so you hear about outages before your customers do. Checks run as often as every 30 seconds, and every failure is confirmed by a second check before an alert goes out, which cuts down on false alarms. Alerts arrive by email, Slack, Discord, Microsoft Teams or webhook when something goes down and again when it recovers, with the downtime recorded. UPKira also tracks response times, server CPU and memory, heartbeat pings from cron jobs and SSL certificate expiry. Hosted public status pages keep users informed during incidents, and agencies can monitor many client sites from one account. The free plan includes 10 monitors with no credit card required.
