Webfreeglobal

Uptime Monitor is a self-hosted, pulse-based uptime monitoring system built with Bun and ClickHouse. Services send heartbeats that trigger alerts when missed, and monitors can be organized into hierarchical groups with dependency-aware notification suppression to avoid alert storms. It offers real-time WebSocket status pages, custom numeric metrics, and multi-channel notifications via Discord, Email, Ntfy, Telegram, and webhooks.
