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.
1. Sematext Synthetics

Updown is a simple tool that monitors the uptime of your website by sending an HTTP request at a predetermined interval that goes down to 15 seconds. Whenever the website isn’t responding, you will get notified via email or SMS. The checks are run from the 8 monitoring nodes, and besides uptime, it does SSL testing, status pages, and performance reports.
For pricing, updown.io went with a simple scheme that allows you to select the number of websites to monitor and the frequency of the checks. For intervals at 15 seconds, every website you track will cost you 2.34 Euros/month.
Picking an uptime monitoring solution is not very difficult, but it does require you to sit down and figure out what you want to achieve. If your goal is just to monitor your uptime, then a one-purpose tool will suffice. However, there is more to monitoring than just uptime. You also need to monitor your APIs, Apdex score, or SSL certificates, in which case you probably need something more complex than a one-trick pony that tells you when your website is down.
Luckily there are monitoring tools like Sematext Synthetics, an end-to-end front-end visibility platform. With a sweet pricing point, starting at just $2 per monitor for a month and highly configurable pricing plans, Sematext will let you understand what is happening behind the scenes. Try it now for 14-days, with no commitment.
