Why we made Semonto and who we are.

Creating a website and server monitoring service for anyone.

Our story

In 2006, I started a side project with some friends. It was a cool web app idea we had. During its development, our hosting was done by a web hosting provider. We noticed that quite often, our web app was unreachable due to problems at the hosting provider. So I wrote a tool to perform periodical tests on the web app and to save the results. These results were processed every month to establish an overview and convert them into uptime reports.

This tool evolved into Semonto, our Server Monitoring Tool. Based on the same concept, we continued to develop and extend the functionalities. Along the way, we added custom tests, custom alert notifications and SSL validation. We also needed to find a way to monitor non-web servers, which resulted in the creation of PulseChecks.

The team grew as well: It started off with one guy, with some help from a designer. Currently, Semonto is developed by a front-end developer and designer as well. And recently a sales and marketing strategist has joined us. We have a private beta program and some ambassadors who help to continuously improve Semonto and supply us with the feedback we really love.
