About 12happy
12happy is a hosted uptime-monitoring service for websites, APIs, and servers. It checks endpoints using HTTP(S), keyword, ping, and TCP port checks, and offers heartbeat monitoring for scheduled jobs on paid plans. It confirms detected failures from a second location before sending alerts and distinguishes slow responses from downtime. Notifications include email, Slack, Telegram, and Android push, with SMS, signed webhooks, escalation policies, and maintenance windows on paid plans. Teams can publish public or password-protected status pages with incident updates and 90 days of uptime history. Teams get role-based access, audit logs, scoped API keys, and two-factor sign-in; agencies can manage clients in separate workspaces. Plan limits and check intervals vary by plan.
