Firebolt vs Knack

Firebolt
Software
Sub-second analytics at cloud data warehouse scale
- From
- $1.84/hour
- Rated
- -
The short version
- 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; Knack plans are priced by number of records and objects rather than users, ranging from $110 to $300 per month as data volume grows
Where they differ
Only the attributes on which Firebolt and Knack actually diverge.
Identical on both: free tier (No), user rating (Not yet rated), category (Unknown).

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
Knack
- Plans are priced by number of records and objects rather than users, ranging from $110 to $300 per month as data volume grows

Which should you pick?
Choose Firebolt if
- You need sub-second queries.
- You work on Cloud (AWS, GCP, Azure preview), Docker, Kubernetes.
- You also want sparse indexes.
Choose Knack if
Nothing in the data separates Knack from Firebolt on the points above - pick on price and on how each one feels to use.
Questions people ask
- Is Firebolt or Knack better?
- Neither clearly leads. Firebolt starts at $1.84/hour and Knack at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Firebolt or Knack?
