What UptimeKit is

UptimeKit is free, open-source monitoring and status-page software available through web, API, or self-hosted deployment. It checks HTTP/HTTPS, TCP, ICMP Ping, DNS, keywords, and HTTP JSON endpoints, and automatically tracks certificate expiration for HTTPS monitors. Users can publish public or private status pages with custom domains and password protection, organize monitors with groups and tags, and create, update, or resolve incidents from the dashboard or integrations. Alerts can go to Discord, Telegram, ntfy, Prometheus AlertManager, Apprise, or custom webhooks. Organizations support team invitations and role-based access. The system is designed for distributed, multi-region monitoring with separate dashboard and worker services and can keep time-series history. Docker Compose deployment requires Docker Engine; PostgreSQL is a prerequisite, while ClickHouse is optional for local deployment. The repository identifies the MIT License.
