Why Uptime Kuma?

With over 11 unique features, open-source code and free of cost nature, Uptime Kuma is one of the best monitoring tools available out there. It gets continuous improvements and can monitor simple websites to more complex environments involving Docker Containers, SQL Databases and game servers.

Monitoring Uptime

Monitoring uptime for any network service is now a breeze, Uptime Kuma can monitor HTTP and HTTPS URLs, TCP Ports and HTTP(s) Keywords, HTTP and HTTPs JSON queries, Databases, Ping IP addresses or Domain Names, DNS records, Steam Game Servers and even Docker Containers.

Beautiful Ping Charts

Who doesn’t love looking at a chart for a better view of the data they have. The Ping monitoring data collected by Uptime Kuma is visualized beautifully by being displayed in a chart that is interactive, fluid and easy to understand. These charts are available for every monitored host you have added.

Short Monitoring Intervals

Uptime Kuma supports very short 20-second monitoring intervals. This means that it can check any hostname, IP, website, Web App, DNS record or Keyword every 20 seconds. This is enterprise-grade monitoring and mostly enough to alert you for any short periods of downtime your infrastructure may be experiencing.

SSL Certificate Monitoring

TLS/SSL Certificate monitoring is now available for your domains or apps. You can check if the URL is reachable via HTTPS or not and if there are any anomalies or incorrect HTTP status codes being sent along with any SSL expirations coming up so you can renew the TLS certificates in a timely manner.

Beautiful UI/UX

If a beautiful dashboard and simplicity are what you are after then look no further. Uptime Kuma offers the sleekest of user interface experiences you will ever come across on a monitoring tool. It is modern, fancy, reactive and very responsive to your instructions.

Receive Notifications

You can receive notifications on the monitored services you have with over 95+ different channels. You can setup Email (SMTP) alerts, Telegram or Signal alerts, Slack Channel alerts, Discord notifications, Splunk, SendGrid, Twilio and even Pushover. Missing a notification for a service, network, app or website is now old school.

Host Multiple Status Pages

Uptime Kuma allows you to create multiple status pages for specific services or domains. Status pages allow you to set communications between you and your customers in an event of a health issue on your systems, current incidents, outages and any real-time information you can provide as an update.

API Keys

If you have a Prometheus Metrics Endpoint and would like to access it you can do so in Uptime Kuma with the use of API keys. By default API keys are not used and only basic HTTP authentication method is used for securing access to the Prometheus metrics endpoint. Once an API key is added the basic HTTP authentication method is disabled.

Multi-Language support

Do you know what would be helpful? Having a network or web monitoring tool in your preferred language. Uptime Kuma is available in over 20+ languages such as English, French, German, Irish, Japanese and Portuguese. It is still being translated to more languages.

Strong Security

Let’s be real for a minute, no one wants their most critical networks, websites, apps or backends being compromised right at a very core component of the infrastructure and servers? Right. Uptime Kuma supports two-factor authentication requiring two forms of identification so it can ask for two forms of access IDs to allow you to login.

Dark and Light Mode

Dark mode lovers, you need to be here. Uptime Kuma offers a beautiful dark mode and light mode interface which you can toggle to Light, Dark and Auto and it will change based on what it can detect on your system theme. You can now treat your eyes to beautiful ping charts in dark mode.

Proxy Support

We know you are not always at your desk at home office and even some tools have to be accessed remotely to help mitigate or investigate an outage or downtime. With Uptime Kuma, you can setup a proxy and access it over the public internet with popular services like Cloudflare, Caddy, HAProxy, Traefik, Apache and Nginx.
