Side by side
DANM vs Flannel
Both stand on container networking software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

DANM offers substantial network and tenant-management controls for self-managed Kubernetes clusters. Its manual deployment and stated Kubernetes compatibility should fit the operator’s environment before adoption.

Flannel provides container networking with several backend choices and documented Kubernetes and Docker environments. Teams should account for its privileged host access, lack of native network-policy enforcement and latest-release-only security fixes.
