npm version GitHub Actions FOSSA Status

Cube is the semantic layer for building data applications. It helps data engineers and application developers access data from modern data stores, organize it into consistent definitions, and deliver it to every application.

Learn more about connecting Cube to data sources and analytics & visualization tools.

Cube was designed to work with all SQL-enabled data sources, including cloud data warehouses like Snowflake or Google BigQuery, query engines like Presto or Amazon Athena, and application databases like Postgres. Cube has a built-in relational caching engine to provide sub-second latency and high concurrency for API requests.

For more details, see the introduction page in our documentation.

Why Cube?

If you are building a data application—such as a business intelligence tool or a customer-facing analytics feature—you’ll probably face the following problems:

  1. SQL code organization. Sooner or later, modeling even a dozen metrics with a dozen dimensions using pure SQL queries becomes a maintenance nightmare, which leads to building a modeling framework.
  2. Performance. Most of the time and effort in modern analytics software development is spent providing adequate time to insight. In a world where every company’s data is big data, writing just SQL queries to get insight isn’t enough anymore.
  3. Access Control. It is important to secure and govern access to data for all downstream data consuming applications.

Cube has the necessary infrastructure and features to implement efficient data modeling, access control, and performance optimizations so that every application—like embedded analytics, dashboarding and reporting tools, data notebooks, and other tools—can access consistent data via REST, SQL, and GraphQL APIs.

We no longer needed a dedicated DevOps team; instead, we actively participated in the industrialization and deployment of our applications through Plural. Additionally, it allowed us to quickly gain proficiency in Terraform and Helm.

Walid El Bouchikhi
Data Engineer at Beamy

I have neither the patience nor the talent for DevOps/SysAdmin work, and yet I've deployed four enterprise-caliber open-source apps on Kubernetes... since 9am today. Bonkers.

Sawyer Waugh
Head of Engineering at Justifi

This is awesome. You saved me hours of further DevOps work for our v1 release. Just to say, I really love Plural.

Case StudyHow Fnatic Deploys Their Data Stack with Plural

Fnatic is a leading global esports performance brand headquartered in London, focused on leveling up gamers. At the core of Fnatic’s success is its best-in-class data team. The Fnatic data team relies on third-party applications to serve different business functions with every member of the organization utilizing data daily. While having access to an abundance of data is great, it opens up a degree of complexity when it comes to answering critical business questions and in-game analytics for gaming members.

To answer these questions, the data team began constructing a data stack to solve these use cases. Since the team at Fnatic are big fans of open-source they elected to build their stack with popular open-source technologies.
