The short version

  • Only Confluent Cloud has a free tier, so it costs nothing to try first.
  • Each has a real cost: Confluent Cloud requires understanding of eCKU (Elastic Confluent Unit) billing; Firebolt compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop

Where each one falls short

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

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
  • Minimum commitment recommended for cost optimization

Firebolt

  • Compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop
  • Storage pass-through charged at $0.0264/GB monthly on compressed data; uncompressed storage could exceed this
  • Azure deployment currently in Preview status; production recommendations unclear
  • Vector indexes limited to float arrays; other data types require alternative indexing strategies
  • Free tier credits ($200) limited; no perpetual free tier for production use
