Better Stack (Uptime)
Uptime monitoring and incident management service that alerts teams when websites or services go down
Uptime Kuma
Self-hosted uptime monitoring with a fancy reactive interface
Easy-to-use self-hosted monitoring tool for tracking uptime across HTTP, TCP, ping, DNS, Docker containers, and more with 90+ notification integrations.
Overview
Overview
Uptime Kuma is a self-hosted monitoring solution designed for teams and individuals who need reliable uptime tracking without depending on third-party services. Built with Vue 3 and powered by WebSocket communication, it delivers a responsive, real-time interface for monitoring infrastructure health.
Capabilities
Monitor diverse endpoints including HTTP(s), TCP ports, ping targets, DNS records, Docker containers, and Steam game servers. Track keyword presence, query JSON responses, or receive push-based health checks. The platform supports 20-second check intervals and displays certificate information, ping charts, and historical data through an intuitive dashboard.
Notifications reach your team through 90+ services including Telegram, Discord, Slack, email, and Pushover. Create multiple status pages mapped to custom domains, enable two-factor authentication, and configure proxy support for complex network topologies.
Deployment
Deploy via Docker with a single command or install directly on major Linux distributions, Windows 10+, and Windows Server 2012 R2+. The application requires Node.js 18/20.4+ and runs on port 3001 by default. PM2 process management is recommended for non-Docker deployments to ensure background operation and automatic restarts.
Highlights
Monitor HTTP(s), TCP, ping, DNS, Docker containers, and 10+ endpoint types
90+ notification integrations including Telegram, Discord, Slack, and email
Multiple customizable status pages with domain mapping support
Real-time WebSocket-powered UI with 20-second check intervals
Pros
- Comprehensive protocol support covering most monitoring scenarios
- Extensive notification service integrations out of the box
- Simple Docker deployment with persistent volume storage
- Active development with 75,000+ GitHub stars and strong community
Considerations
- Does not support FreeBSD, OpenBSD, NetBSD, or platform-as-a-service hosts like Replit
- Network file systems (NFS) are explicitly unsupported for data storage
- Minimum 20-second check intervals may not suit high-frequency monitoring needs
- Non-Docker installation requires manual dependency management and PM2 configuration
