DevStand is a developer-experience tool aimed at Kubernetes-based application development, focused on visually authoring and validating Kubernetes manifests and Dockerfiles from within an IDE. It sits in the same general space as Lens, Monokle, and Headlamp, emphasizing a GUI-first workflow over editing raw YAML.
Information about the project is limited and the upstream is not heavily maintained. If you are evaluating tooling in this area, the more actively developed alternatives are Monokle (for manifest editing and validation), Lens or Headlamp (for cluster navigation), and Tilt or DevSpace (for in-cluster inner-loop development).
