The short version

  • Only Envoy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Confluent Cloud basic tier caps at 1,500 partitions and 5TB storage per confluent.io pricing page (Aug 2026); Standard clusters start around $385 per month before usage; Envoy licensed under Apache License 2.0 per the project's GitHub repository (envoyproxy/envoy LICENSE); as a CNCF graduated project it has no paid tier or vendor price to compare
