Firebolt review
A flexible lakehouse database with autoscaling SQL, streaming, vector search, and AI functions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Firebolt is an open-source analytical database for engineers building real-time analytics, AI applications, and ELT workflows. It supports PostgreSQL-compatible SQL and can run as a single binary on a laptop or as a distributed cloud cluster. Managed and self-hosted deployment options, object-storage architecture, and workload isolation make it suited to teams that need a hybrid approach across batch and streaming data.
Pricing is usage-based. The published managed-service rate is $0.92 per hour for a compute-optimized S engine, billed monthly, with compute billed per second. That plan includes scale to zero and auto scaling, while the displayed compute rate excludes storage. Firebolt Core is free forever and self-hosted. This model fits teams that want to align compute use with workloads, but teams seeking a straightforward flat monthly warehouse package may prefer another option.
Firebolt’s strongest differentiator is the combination of lakehouse access and built-in AI capabilities. It can query Apache Iceberg and other data-lake files, ingest Kafka streams with exactly-once delivery, provide native vector search with HNSW indexes, and run SQL-based AI functions and embeddings. Connectivity includes REST, JDBC, SDK, and the Postgres wire protocol, with integrations for AWS Glue, Databricks Unity Catalog, dbt, BI tools, Airflow, LangChain, and Amazon Bedrock. Choose Firebolt when engineering control, open-source deployment, streaming, and AI workloads matter; choose an alternative if your priority is a simpler managed experience.
Firebolt pros and cons
- Where it wins
- Separate compute and storage with autoscaling and scale-to-zero
- Iceberg queries and exactly-once Kafka streaming ingestion
- Native vector search and SQL-based AI functions
- Where it doesn't
- The $0.92/hour managed compute rate excludes storage
- Free Core is self-hosted rather than managed
- Usage-based pricing may not suit teams seeking flat monthly costs
