Summary

Spice.ai OSS is an open-source SQL query and AI-inference engine built in Rust for developers. Its SQL API queries structured and unstructured data across databases, data warehouses, and data lakes. Data can be materialized in DuckDB, SQLite, or PostgreSQL, in memory or on disk, with results caching included. The AI compute engine offers an OpenAI-compatible API for local and hosted inference, search, memory, evaluations, and observability. Search options include vector, BM25 full-text, and hybrid methods exposed through SQL table-valued functions. Spice lists more than 40 data connectors, including PostgreSQL, MySQL, S3, Snowflake, Databricks, and DuckDB. It also documents integrations with SQL and BI clients such as DBeaver, JetBrains DataGrip, Apache Superset, Tableau, and Microsoft Power BI. Monitoring options include Prometheus-compatible metrics, OpenTelemetry metric export, and Zipkin tracing. Spice runs as a binary, container, Kubernetes workload, or managed app on Spice Cloud. The software is free under Apache 2.0 and can be self-hosted. Listed operating system support includes macOS with Apple Silicon, Linux on x86_64 or aarch64, and Windows 10 or later with WSL.

Who it is for

It suits developers who need SQL access across varied data sources alongside AI inference capabilities. Its deployment options include self-hosted binaries, containers, and Kubernetes workloads.

What is good

SQL API queries structured and unstructured data.
Supports more than 40 data connectors.
Offers vector, BM25, and hybrid search.
Free under Apache 2.0.

What to know first

Windows support requires WSL.
