Better Stack

Better Stack (formerly Better Uptime) combines uptime monitoring, status pages, and incident management into a polished platform. Its pricing starts at $29/month for the Team plan, with higher tiers needed for advanced features like multi-region monitoring, longer data retention, and more monitors.

Uptime Kuma is the standout open source uptime monitoring tool — it provides HTTP, TCP, DNS, Docker, and keyword monitoring with a beautiful real-time dashboard, notification integrations (Slack, Discord, Telegram, email, webhooks), and public status pages. It's one of the most popular self-hosted monitoring tools, with 60,000+ GitHub stars. OpenStatus offers a modern, open source status page and monitoring platform with edge-based monitoring from multiple global regions, synthetic monitoring, and a clean public status page builder.

Uptime Kuma's notification flexibility is a key advantage. It supports 90+ notification services out of the box — far more than Better Stack's built-in integrations. Whether your team uses Slack, Discord, Microsoft Teams, PagerDuty, or a custom webhook, Uptime Kuma connects to it.

The self-hosting setup is trivial — Uptime Kuma runs as a single Docker container and monitors start sending alerts within minutes. For teams monitoring 20-50 endpoints (websites, APIs, databases), self-hosted Uptime Kuma provides comprehensive monitoring at the cost of a $5/month VPS. The same monitoring scope on Better Stack requires the Team plan or higher, costing $29-85/month.
