Firebolt

Firebolt is an open-source analytical database for engineers who need fast SQL analytics and control over where workloads run. It suits teams moving between local development, self-managed cloud clusters and a managed service, especially when open lake storage matters. Its strongest case is flexible, low-latency analytics; AWS-only managed hosting and several integration boundaries narrow the fit.

Overview

Firebolt uses Postgres-compatible SQL and is designed for sub-second queries under high concurrency. The same product can run as a zero-dependency single binary on a laptop or scale to clusters of hundreds of nodes in your cloud. That range serves both developers who want a lightweight starting point and platform teams that require their own infrastructure, but self-managed deployments also leave operations, upgrades and capacity decisions with you.

Deployment choices include the single binary, a Helm chart, a Kubernetes Operator and a fully managed service. Separate storage and compute, streaming ingestion, and support for Apache Iceberg and DuckLake make it suitable for lake-oriented architectures based on open storage standards rather than a closed storage layer.

Key features

Managed compute is charged per second and can scale to zero, start and stop automatically, and scale automatically with demand. Those controls are useful for intermittent or changing workloads because idle compute need not remain running. Object storage is billed separately at $0.0264 / GB·mo, so total managed cost depends on retained data as well as query activity. The managed service includes $200 in free credits, giving new deployments room to evaluate usage before compute charges become the deciding factor.

AI functions include AI_QUERY, AWS_BEDROCK_AI_QUERY and AI_EMBED_TEXT, alongside HNSW vector indexes and VECTOR_SEARCH. An MCP Server and a preview Firebolt Agent extend the database toward AI-assisted applications, though the Agent is not presented as a finished capability. Traditional analytics tooling is well covered: Looker, Tableau and Power BI can connect, as can Postgres-compatible clients and Go, JDBC, .NET, Node.js, Python, Rust, SQLAlchemy and REST API applications.

Data-platform integrations include dbt Core, Airflow 2.x, Confluent Kafka, Apache Iceberg catalogs, Databricks Unity Catalog, Snowflake Open Catalog and AWS Glue. The boundaries matter: the native dbt adapter is for dbt Core, Airflow 3.x is unsupported, and Delta Lake has no native support. Teams standardising on those technologies should verify that their existing pipelines do not depend on the missing versions or format.

Security and governance features include SOC 2 Type II, ISO 27001, ISO 27018, HIPAA support, GDPR alignment, MFA, role-based access control, encryption in transit and at rest, plus audit logs and metrics in the managed service. These provisions make Firebolt more credible for regulated or centrally governed environments, while self-managed customers remain responsible for operating their chosen deployment.

Pricing

Firebolt Core

Firebolt Core costs nothing, billed free forever, and is self-hosted with no usage limits. It is the clearest option for developers, experiments and teams that want complete control without a license bill. The important commercial restriction is that Core cannot be used to build a hosted SaaS competing with Firebolt’s managed service, so it is unsuitable as the database behind a competing multi-tenant offering. The plan supports hybrid deployment, separate storage and compute, data-lake use and streaming ingestion, but self-hosting still carries infrastructure and operational work.

Managed service

The managed service uses usage-based compute billing per second, with $200 in free credits. Scale-to-zero and automatic start, stop and scaling can limit waste for elastic workloads; object storage remains a pass-through charge of $0.0264 / GB·mo. Choose this route when avoiding cluster operations is worth variable billing. Choose Core instead when predictable infrastructure ownership, unlimited free usage and self-management are more important.

Platforms

Firebolt is available through its API, Linux deployments, self-hosting and the web. Self-managed Firebolt is generally available on AWS and GCP and in preview on Azure. The fully managed service is currently offered only on AWS, making self-management the practical path for teams committed to GCP or Azure.

Who it's for

Firebolt fits engineering and data-platform teams building high-concurrency analytics, lakehouse workloads or streaming pipelines that benefit from Postgres-compatible SQL and open storage. It is also a good match for organisations that want to begin with a local binary and later move to Kubernetes or managed compute. Look elsewhere if you require native Delta Lake, Airflow 3.x or dbt adapters beyond dbt Core, or if a managed service in GCP or Azure is essential.

Pros and cons

Pros

• Flexible deployment: A single binary, Kubernetes tooling and managed hosting cover development through large clusters.
• Fast concurrent analytics: Sub-second query design targets demanding interactive workloads.
• Open lake compatibility: Apache Iceberg, DuckLake and separated storage and compute suit open data architectures.
• Elastic managed billing: Per-second compute, scale-to-zero and automatic scaling align cost with variable demand.
• Broad connectivity: Major BI tools, programming languages and catalog platforms are supported.

Cons

• Managed AWS constraint: The fully managed option does not currently cover GCP or Azure.
• Ecosystem gaps: Airflow 3.x, native Delta Lake and dbt adapters beyond dbt Core are not supported.
• Operational burden on Core: Self-hosted users run the infrastructure themselves.
• SaaS restriction: Core cannot power a hosted service competing with Firebolt managed service.
• Storage is extra: Managed users pay object-storage pass-through charges in addition to compute.

Verdict

Choose Firebolt if you need fast, concurrent analytical SQL with the freedom to run a free self-hosted binary, operate your own cloud cluster or use elastic managed compute. Its open-storage support and broad tooling strengthen the case for modern lake architectures. Look elsewhere when AWS-only managed hosting, missing Delta Lake or Airflow 3.x support, or the Core plan’s competing-SaaS restriction conflicts with your platform strategy.
