Bluewave vs Uptime Kuma: A Real-World Comparison for Monitoring Uptime and Beyond

In today’s digital landscape, service reliability isn’t just a technical requirement—it’s a business imperative. Whether you’re running a small personal blog or managing enterprise-level infrastructure, knowing when your systems are down is critical. This is where uptime monitoring tools come into play, providing visibility into service availability and performance.

This article examines two popular self-hosted monitoring solutions: Uptime Kuma and BlueWave Uptime. We’ll explore their features, deployment processes, strengths, and limitations to help you make an informed decision for your monitoring needs.

Understanding Uptime Monitoring

Before diving into the comparison, let’s clarify what uptime monitoring is and why it matters.

Uptime monitoring is the process of continuously checking whether a service, website, or application is operational and accessible. It provides critical insights into:

• Service availability
• Response times
• Performance trends
• Potential bottlenecks
• Historical reliability data

Effective monitoring enables teams to:

• Respond quickly to outages before users report them
• Meet service level agreements (SLAs)
• Identify patterns in system failures
• Build trust with customers through transparent status reporting
• Make data-driven infrastructure decisions

Now, let’s examine our two contenders.

Error Handling

BlueWave Uptime implements standardized error handling. Errors are returned in a consistent format:

{
  "success": false,
  "msg": "No token provided"
}

For developers extending BlueWave Uptime, errors should be structured with the following parameters:

Example error handling implementation:

const myRoute = async(req, res, next) => {
  try {
    const result = myRiskyOperationHere();
  }
  catch(error) {
    error.status = 404;
    error.message = "Resource not found";
    error.service = "serviceName";
    next(error);
    return;
  }
}

Note: Errors should be handled by middleware, not at the controller level.
