10 Best Website Uptime Monitoring Tools in 2023

Better Stack Team
Updated on January 4, 2023

The attention span of a modern customer is getting smaller every day, and with the number of distractions that our interconnected world offers, it is getting rather ruthless out there. Statistically, one in nine customers who visit your web during any outage or downtime will never come back. That's almost a 10% loss if downtimes occur frequently enough. Luckily, there is a ton of software and tools to monitor your webpage uptime and performance.

What is Uptime?

Before we dig into the list, we need to understand some key terms. Uptime represents the time during which your website and its contents are fully operational and available. It is measured in percent of the time, meaning that if your web is available 99% of the time, you are looking at more than 7 hours of downtime each month.

Downtime, as the word suggests, is the time when a part of or your entire service fails to operate. This causes disruptions and loss of potential clients. Each downtime should be properly registered, evaluated, and informed upon, and that's where uptime monitors come in.

However, monitoring goes far beyond this bipolar of on/off system. Your website can be online and still perform poorly. It might be because of a location-related issue, slow-loading times and bad optimization, or failures during peak hours. All this data is crucial for success and could potentially decide whether you will break through or not. Deciding to work with external website monitors allows you to prevent failure, where others have already failed, and instead, prevent getting there in the first place.

Now, let's take a look at the synthetic monitoring toolbox and specifically at the best website uptime monitoring solutions in 2023.
