Cube is a semantic layer for analytics. Metrics, dimensions, joins and access rules are defined once in code and then exposed through SQL, REST and GraphQL APIs to BI tools, custom applications and AI agents. Cube Core is the open-source, headless edition without a user interface, with a built-in cache for fast dashboards, and works with SQL sources such as Snowflake, Databricks, BigQuery and Postgres. Cube Cloud is the managed service, adding chat-based analytics, workbooks, dashboards and embedded analytics.
The client packages are licensed under MIT and the backend packages under Apache 2.0. Cube is developed by Cube Inc., a US company based in San Francisco. If you run Cube Core yourself, you decide where your data resides. Cube Cloud runs on AWS, GCP or Azure; the public documentation does not list the available regions, so ask whether a European region is possible. When the US company Cube Inc. operates the service, it falls under US jurisdiction, including the CLOUD Act.
