# Firebolt Core

Firebolt Core is a free, self-hosted edition of [Firebolt's distributed query engine](https://www.firebolt.io/) available as a [project on GitHub](https://github.com/firebolt-db/firebolt-core). It provides high-performance data warehousing capabilities that can be deployed anywhere from a single laptop to enterprise datacenters.

The product is designed for users who need low-latency, high-concurrency analytics but require self-hosted deployment due to cost considerations, data sovereignty requirements, or existing on-premise infrastructure.
