Cluster.dev started as an in-house SHALB projectOver the years, SHALB has successfully implemented over 100 infrastructures of different complexity. The skills and knowledge we have developed along the way inspired us to create a tool that could help automate a large part of our DevOps services. This is how the idea of Cluster.dev assumed its shape. So, we started Cluster.dev primarily to address our challenges. Soon after, inspired by warm feedback, we decided to open-source it to the world. Currently, we invest in the product our time, hire third-party employees, and engage the open-source community in the development of essential features. After all, we are interested in Cluster.dev enhancement as no one else, as long as it helps tackle our pain points!
