Argo CD vs. Flux - a Detailed Comparison
GitOps has undoubtedly been a hot topic for quite some time now. Ever since the emergence of the popularity of Kubernetes, many organizations that have been adopting Kubernetes come to quickly realize the challenges that come with managing it. This gave rise to the paradigm known as “GitOps”. GitOps has come to be the operating model for Kubernetes in many organizations - to which it has been adopted by Platform Engineers, DevOps Engineers, and SRE teams alike.
When organizations are on their Kuberntes adoption journey, they undoubtedly run into two big players when researching GitOps: Argo CD and Flux. A tale as old as Ford vs Chevy and VIM vs Emacs - the two major players in this space both have a large community, large user base, and seemingly have the same end goal of easing the use of Kubernetes via GitOps. Both projects have reached graduation status in the CNCF and both projects continue to grow.
So, the elephant in the room is the very question that we aim to address: What are the differences between Flux and Argo CD?

In-Depth Look
Trying to summarize the comparison of the two tools in a single blog proved to be too difficult to do. There are just too many nuances that needed explaining and we felt it would be a disservice to edit them out. Therefore, we have collected all the findings of the comparison in an in-depth whitepaper!
