Spice.ai OSS vs Starburst Galaxy

Spice.ai OSS is a free, 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 engine provides an OpenAI-compatible API for local and hosted inference, search, memory, evaluations, and observability. Search methods include vector, full-text BM25, and hybrid approaches exposed through SQL table-valued functions. Spice lists over 40 data connectors, including PostgreSQL, MySQL, S3, Snowflake, Databricks, and DuckDB, and documented client integrations include DBeaver, JetBrains DataGrip, Apache Superset, Tableau, and Microsoft Power BI. It can run as a binary, container, Kubernetes workload, or managed app on Spice Cloud. The Apache 2.0-licensed software is self-hostable as a binary or Docker image. Listed operating systems are macOS with Apple Silicon, Linux on x86_64 or aarch64, and Windows 10 or later with WSL.

Starburst Galaxy is a managed cloud analytics platform built on Trino. It lets teams query data across sources in one SQL query without copying it, with availability on AWS, Google Cloud and Microsoft Azure. Starburst lists more than 50 data sources, including Amazon S3, Snowflake, Redshift, BigQuery and Azure Blob. Galaxy can stream from Kafka or load CSV, JSON and AVRO files into Iceberg. Its LakeOps service automates Iceberg table compaction, snapshot expiry and orphan-file removal; AIDA converts natural-language questions into governed insights through a customizable interface or MCP. Security provisions include fine-grained RBAC and ABAC, encryption, data classification and private connectivity. Starburst describes Galaxy as SOC 2 Type II certified and HIPAA-ready. A free plan allows up to three clusters for ad hoc queries in standard execution mode. Usage charges vary by plan and cover items such as compute, ingestion and private-link data transfer. A 30-day trial includes Enterprise features and $500 in compute resources. Starburst recommends Galaxy for organizations without resources to manage complex data clusters.
