What is Uptime Kuma?

Uptime Kuma is an open source, self-hosted monitoring tool that tracks whether your websites, APIs, and services are up and running. Think of it as a self-hosted alternative to Uptime Robot. You install it on your own server (or run it via Docker), configure your monitors, and get notified through Slack, Discord, Telegram, email, or any of 50+ supported channels when something goes down.

The project exploded in popularity since its 2021 launch, racking up over 60,000 GitHub stars. Its appeal is simple: it does one thing really well, looks great doing it, and costs nothing to run.

Key Features

Multi-Protocol Monitoring

Uptime Kuma supports HTTP(S), TCP, DNS, Docker container, ping, and more. You can monitor websites, APIs, game servers, mail servers, and internal services. Each monitor has configurable intervals, retry logic, and accepted status codes. The flexibility covers most monitoring scenarios without needing multiple tools.

Beautiful Status Pages

You can create public or private status pages that show the uptime history of your services. These are clean, modern, and customizable with your own branding. You can group monitors, add custom descriptions, and share the page with clients or users. It looks professional enough to replace paid status page services.

50+ Notification Integrations

When a monitor detects downtime, Uptime Kuma can alert you through Slack, Discord, Telegram, Microsoft Teams, PagerDuty, Pushover, Gotify, email (SMTP), webhooks, and dozens more. Setup is straightforward, and you can assign different notification channels to different monitors.

Certificate Monitoring

For HTTPS monitors, Uptime Kuma automatically tracks SSL certificate expiration. It warns you days before a certificate expires so you never get caught off guard by an expired cert taking down your site.

Docker Integration

If you run Docker, Uptime Kuma can monitor container health directly through the Docker socket. No need to expose HTTP endpoints just for monitoring. It checks container status and alerts you when containers stop or become unhealthy.

Pricing

Uptime Kuma is completely free and open source (MIT license). There are no paid tiers, no premium features locked behind a paywall, and no hosted version. You self-host it on your own infrastructure. The only cost is the server to run it on, which can be as cheap as a $5/month VPS.

Pros

• Completely free with no feature restrictions or usage limits
• Exceptionally polished UI for an open source project
• 50+ notification integrations covering every major platform
• Dead simple Docker deployment (one container, one command)
• Active development with frequent releases and responsive maintainer

Cons

• Self-hosted only, no managed cloud option available
• Single-location monitoring (can only check from where it is installed)
• No built-in incident management or on-call rotation
• SQLite backend may struggle with very large numbers of monitors

Who Should Use Uptime Kuma?

Uptime Kuma is perfect for developers, freelancers, and small teams who want reliable uptime monitoring without paying monthly fees. If you already have a VPS or homelab, running Uptime Kuma costs you nothing extra. Freelancers monitoring client sites get particular value from the status page feature. If you need multi-location monitoring, synthetic checks, or incident management workflows, a paid service like Better Stack or Datadog will serve you better.

Alternatives

Uptime Robot

Uptime Robot is the most popular free uptime monitoring service. It monitors from multiple locations and requires zero infrastructure. The free plan covers 50 monitors at 5-minute intervals. Better for people who do not want to self-host. Worse for privacy-conscious users and those needing custom status pages.

Better Stack

Better Stack (formerly Better Uptime) combines uptime monitoring with incident management, on-call scheduling, and status pages. It is a fully managed service with a generous free tier. Better for teams that need incident workflows. More expensive than self-hosting Uptime Kuma.

Hetrixtools

Hetrixtools offers uptime monitoring from 15+ global locations with blacklist monitoring and server resource tracking. The free plan includes 15 monitors. Better for multi-location checks. Less polished UI compared to Uptime Kuma.

FAQ

How do I install Uptime Kuma?

The easiest way is Docker: run a single command to pull and start the container. It also runs on Node.js directly if you prefer. The setup wizard walks you through creating your admin account.

Can Uptime Kuma replace Uptime Robot?

For most use cases, yes. The main trade-off is that Uptime Kuma monitors from a single location (your server), while Uptime Robot checks from multiple data centers. If single-location monitoring is acceptable, Uptime Kuma is more feature-rich.

Is Uptime Kuma suitable for production use?

Yes. Many companies and developers use it in production. The project is actively maintained with regular security updates. Just make sure to run it on reliable infrastructure and keep backups of the SQLite database.

Does Uptime Kuma support API access?

Not natively through a REST API, but it does expose a Socket.IO interface that you can interact with programmatically. Third-party tools and scripts exist to manage monitors via code.
