12 Best Website Uptime Monitoring Tools & Services [2023 Reviews]

Uptime is the metric that measures perhaps the most critical aspect of your business, its availability. If you think about it, having a website that does many really cool things, paying tons of money on ads to bring people to it, and even spending all those hours on making your website look great won’t amount to anything if it doesn’t work. Furthermore, according to a study made by Google, even a one-second delay in loading your site can cause conversions to go down by 20 percent. Luckily there are many ways to track your uptime, from open-source to closed-source, free to enterprise-grade, and pretty much anything in between. To help you get started, in this post, I’ll review some of the best uptime monitoring tools available today.
