Docker Swarm : There is no GUI.
Kubernetes : Highly scalable and scales fast.
Docker Swarm : Highly scalable and scales 5x faster than Kubernetes.

Docker Swarm : Docker swarm cannot do auto-scaling.
Kubernetes : Manual intervention needed for load balancing traffic between different containers and pods.
Docker Swarm : Docker swarm does auto load balancing of traffic between containers in the cluster.
Rolling Updates & Rollbacks
Kubernetes : Can deploy rolling updates and does automatic rollbacks.
Docker Swarm : Can deploy rolling updates, but not automatic rollback.
Kubernetes : Can share storage volumes only with the other containers in the same pod.
Docker Swarm : Can share storage volumes with any other container.
