The short version

Only QuestDB has a free tier, so it costs nothing to try first.
Each has a real cost: Firebolt compute billed per second on Arm-based processors; small instances still incur measurable costs during idle periods despite auto-stop; QuestDB open-source edition lacks high-availability, distributed architecture, and enterprise security features
They diverge on capability: Firebolt covers Sub-second Queries, QuestDB covers High Throughput Ingestion.

Where each one falls short

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

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

QuestDB

Open-source edition lacks high-availability, distributed architecture, and enterprise security features
Enterprise edition pricing not published; requires contacting sales for custom quote
Ingestion limit of 20M rows/sec platform-dependent; may not scale to extreme throughput requirements
