What it is

Cube Core is an open-source semantic layer that defines metrics, dimensions, joins, and access rules once and exposes them via SQL, REST, and GraphQL APIs. It sits between data sources (Snowflake, BigQuery, Postgres, Presto, Athena) and downstream consumers (BI tools, embedded analytics, AI agents), with a built-in relational caching engine for sub-second latency. Unlike proprietary BI platforms, it's headless and reusable across multiple analytics applications. Monorepo structure: packages/cubejs-api-gateway/ contains the HTTP/WebSocket gateway and request handling; packages/cubejs-backend-native/ is a Rust FFI layer handling auth, routing, and streaming;…

Start here

Read these in order:

• packages/cubejs-client-react/src/types.ts — Foundation: doesn't import anything internally and is imported by 11 other files. Read first to learn the vocabulary.
• packages/cubejs-cli/src/utils.ts — Foundation: imported by 10, no internal dependencies of its own.
• packages/cubejs-playground/src/QueryBuilderV2/hooks/event.ts — Built on the foundation; imported by 9 downstream files.
• packages/cubejs-playground/src/QueryBuilderV2/components/ListMemberButton.tsx — Built on the foundation; imported by 7 downstream files.
• packages/cubejs-playground/src/atoms/index.tsx — Layer 2 — composes lower-level code into reusable abstractions (imported 5×).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/cube-js/cube.git
cd cube
# Verify package.json exists in packages/ subdirectories; assume npm/yarn workspace
npm install  # or yarn install
# For native Rust components, ensure Rust toolchain is installed

Exact setup steps depend on manifest files not shown—verify package.json at repo root and in packages/cubejs-api-gateway/ and packages/cubejs-backend-native/ before running.

Daily commands:

Clone and run npm install in repo root (assumes npm workspaces). Then:

# To run API gateway dev server (if applicable):
cd packages/cubejs-api-gateway
npm run dev  # or similar; verify package.json for actual script

# For native Rust components, build with:
cargo build  # in packages/cubejs-backend-native/

Verification needed: Check actual package.json scripts under each package; no build/dev commands are visible in the provided data.

Key cautions & unknowns

• Scorecard: default branch unprotected (0/10)
• Environment Setup: The Rust native backend (cubejs-backend-native/) requires a Rust toolchain installed alongside Node.js; build will fail if rustc is missing. FFI Boundaries: Python integration via…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
