The short version
- Only Microsoft SQL Server 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; Microsoft SQL Server licensing and on-premises deployment costs are high compared to open-source alternatives, with Enterprise Edition exceeding $60,000 for minimum core requirements
- They diverge on capability: Firebolt covers Sub-second Queries, Microsoft SQL Server covers T-SQL.

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
Microsoft SQL Server
- Licensing and on-premises deployment costs are high compared to open-source alternatives, with Enterprise Edition exceeding $60,000 for minimum core requirements
- Performance monitoring toolset is insufficient for hybrid cloud environments requiring real-time analytics across multiple deployment types
- Heavy I/O resource consumption can saturate disk volumes and degrade performance when processing large transaction workloads
- Always On availability groups with up to 8 secondary replicas are limited to Enterprise edition only; Standard supports only basic availability groups with 2 replicas
- CPU and memory scaling is capped at 4 sockets or 32 cores on Standard edition, limiting deployments requiring higher compute capacity

Questions people ask
- Is Firebolt or Microsoft SQL Server better?
- Neither clearly leads. Firebolt starts at $1.84/hour and Microsoft SQL Server at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Firebolt or Microsoft SQL Server?
- Microsoft SQL Server has a free tier; the other does not. Paid plans start at $1.84/hour for Firebolt and Free for Microsoft SQL Server.
- Does Firebolt or Microsoft SQL Server run on more platforms?
- Firebolt runs on Cloud (AWS, GCP, Azure preview), Docker, Kubernetes. Microsoft SQL Server runs on Windows Server, Linux (RHEL, SUSE, Ubuntu), Docker, Azure.
- Can I use Microsoft SQL Server for free?
- Yes. Microsoft SQL Server has a free tier, so you can try it without paying. Firebolt starts at $1.84/hour.
- What is Firebolt best used for?
- Firebolt is most often used for data analytics teams running gigabyte-to-petabyte datasets with sub-second query requirements, real-time business intelligence platforms requiring acid transactions and snapshot isolation, applications needing vector search on analytical data for similarity queries. Of those, data analytics teams running gigabyte-to-petabyte datasets with sub-second query requirements and real-time business intelligence platforms requiring acid transactions and snapshot isolation are not what Microsoft SQL Server is typically brought in for.
- What can Firebolt do that Microsoft SQL Server cannot?
- Firebolt covers Sub-second Queries, Sparse Indexes, Data Pruning, Decoupled Storage/Compute. Microsoft SQL Server covers T-SQL, ACID Compliance, Advanced Security, In-memory OLTP.
Answered from the vendors’ own pages
Microsoft SQL Server: What is the pricing model for SQL Server?
SQL Server uses core-based licensing with per-2-core pack pricing. Enterprise Edition costs approximately $15,123 per 2-core pack (minimum 8 cores). Standard Edition costs approximately $3,945 per 2-core pack. Developer and Express editions are free. Software Assurance adds 25-35% annually for upgrades and support.
SourceMicrosoft SQL Server: Does SQL Server run on Linux?
Yes. SQL Server 2017 and later run on Linux (Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Ubuntu), Docker containers, and Windows with feature parity including Always On availability groups, Active Directory authentication, and encryption.
SourceMicrosoft SQL Server: Is there a free edition of SQL Server?
Yes. SQL Server Express is free and includes all functionality of Enterprise edition for development and testing, with limits of 4 cores, 1,410 MB memory per instance, and 50 GB per database. Developer edition is also free for non-production use.
SourceMicrosoft SQL Server: Can SQL Server be deployed offline?
Yes. SQL Server can be installed from offline media on machines without internet access. Microsoft provides complete offline installation packages for SQL Server, SSMS, and supporting components, making deployment in isolated or air-gapped environments feasible.
SourceMicrosoft SQL Server: What high availability options does SQL Server provide?
SQL Server offers Always On availability groups (Enterprise only), Always On failover cluster instances, database mirroring, log shipping, and for disaster recovery, failover servers in Azure and Accelerated Database Recovery for faster recovery after failures.
