What is it?

SuperSonic is an open-source platform for analytics that pairs a natural-language query interface, where business users ask questions and receive charts, with a headless semantic layer, where analytics engineers define metrics, dimensions and their relationships. The semantic model serves both paths: the LLM-based Text2SQL pipeline uses it for context retrieval to reduce hallucinated fields, and the same model is exposed through a Headless BI query API.

The pipeline is split into components: a knowledge base that indexes schema elements, a schema mapper that matches query terms against it, semantic parsers and correctors that combine rule-based and LLM-based logic, and a translator that produces executable SQL. Chat plugins for third-party tools and chat memory for few-shot recall are also included. Access control covers dataset, column and row levels, and custom components can be added through Java SPI.

The project is written in Java and can be run with Docker Compose or from a prebuilt binary that starts as a standalone service.

Key features

  • 01Natural-language querying with automatic chart visualization for business users.
  • 02Headless semantic layer for defining metrics, dimensions and entity relationships.
  • 03Hybrid rule-based and LLM-based semantic parsing and correction.
  • 04Dataset, column and row-level access control.
  • 05Multi-turn conversation, input auto-completion and post-query recommendations.
  • 06Extensible through Java SPI and third-party chat plugins.

Use cases

  • Letting non-technical staff ask questions of company data in plain language.
  • Building a governed semantic model that both dashboards and an LLM query against.
  • Adding a natural-language API on top of an existing metrics layer.
  • Prototyping Text2SQL pipelines with rule-based and LLM components.
