UPKira

UPKira is uptime monitoring for websites, APIs, online stores, servers and cron jobs. Each failure is confirmed by a second check before an alert goes out through channels such as email, Slack, Discord, Teams or webhooks. It also covers SSL certificate expiry, cron heartbeat pings and public status pages with incident history. The free plan includes 10 monitors with checks every 5 minutes and no credit card required, and paid plans check as often as every 30 seconds.
