Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Argo CD

  • Licensed under Apache License 2.0 per the project's GitHub repository (argoproj/argo-cd LICENSE); as open source software it has no paid tier or vendor price to compare
  • The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
