Gatus
This is a health dashboard to monitor the availability and health of services using various network protocols such as HTTP, ICMP, TCP, and DNS queries. It allows users to define custom health checks for their applications or infrastructure components by evaluating criteria like HTTP status codes, response times, certificate expiration, and response contents. What sets Gatus apart is its proactive monitoring approach, where it can alert users ahead of client impact, traditional metrics-based tools that depend on existing traffic or client requests to detect issues. This makes it an essential tool for operators who want to maintain high service reliability by being immediately informed of potential problems before customers encounter them.
Why Use Gatus?
Many traditional monitoring systems like Prometheus’ Alertmanager, CloudWatch, or Splunk primarily rely on monitoring metrics generated by live traffic or application logs. While these are invaluable for observing trends and spotting errors, they fail to provide warnings when an endpoint or service is down but no client traffic arrives to trigger alerts. With Gatus, users can configure scheduled health checks that independently and actively request service endpoints at defined intervals to ensure they function correctly. This gives teams early notice of outages or degraded performance, providing an opportunity to respond proactively.
For small businesses, Gatus offers a solution because it is easy to deploy and lightweight in resource usage. Its configuration is straightforward and expressive, requiring no deep expertise to start monitoring critical endpoints. Small businesses often lack dedicated monitoring teams or expensive commercial monitoring tools, so having a tool like Gatus that offers both continuous, proactive monitoring and flexible alerting integrates well into their operational workflows. It helps to ensure business-critical services remain up without involving large operational overhead or complex setups. Furthermore, Gatus supports various alert integrations including Slack, Discord, PagerDuty, and email, which are commonly used by small teams, enabling timely communication in case of issues.
Features
It is rich in features that make it versatile and good for both developers and operators. One of its notable features is the flexible condition system. Beyond simple HTTP status checks, users can set conditions based on response times, content in the response body using JSONPath expressions, the IP address of the endpoint, TLS certificate expiry, and DNS query results. This flexibility allows users to customize health checks according to the specific needs of their environments.
Gatus also supports the creation of automated user acceptance tests by defining suites of sequential endpoints with shared context. This enables more complex scenarios, such as testing multi-step authentication flows, API workflows involving chained requests, business process validations across services, and data consistency checks.
Licensing and Community
This is an open-source project hosted on GitHub, licensed under the MIT License. This permissive license allows free use, modification, and distribution with minimal restrictions, favoring adoption by individuals, small businesses, and enterprises alike. The license promotes community contributions and transparency, encouraging users to extend or customize the tool to their specific needs.
The project has an active community around it, providing documentation, examples, and support through GitHub discussions and issues. The repository includes guides for deployment with Docker and Kubernetes, along with many examples of configuration files.

The configuration format is designed to be human-readable and easy to manage, allowing quick addition or changes to monitored endpoints. Gatus can run in Docker containers or directly as a binary, making deployment straightforward on various platforms.
Another strength is its alerting system. It supports numerous notification providers out of the box, including Slack, Microsoft Teams, PagerDuty, Twilio, Discord, and email. Users can fine-tune the alerting behavior by specifying thresholds for failures and recoveries, reminder intervals, and custom alert descriptions. This ensures teams receive meaningful alerts with minimal noise.
From a usability perspective, the dashboard offers a visually pleasing and informative status overview with features such as badges displaying uptime and response times, dark mode for better viewing comfort, and sorting/filtering options to quickly find relevant endpoints. It also offers metrics export for integration with external analysis systems.
Lastly, Gatus is efficient in resource consumption, typical of applications developed in Go, meaning it can run effectively on modest hardware without adding operational cost or complexity.
