About VulcanSQL

VulcanSQL is a data API framework that lets data professionals expose analytical data as RESTful APIs by writing SQL. It targets AI agents and data apps that need controlled access to databases, data warehouses or data lakes, replacing much of the hand-written API code that normally sits between the two.

The README frames the problem as slow and error-prone custom API development, the complexity of integrating diverse data sources, and the work of making APIs secure and compliant with regulations such as GDPR and HIPAA. VulcanSQL aims to standardize the approach so APIs follow consistent conventions. Its topics list integrations with BigQuery, DuckDB, PostgreSQL, Snowflake, ClickHouse and ksqlDB.

It is written in TypeScript and released under Apache-2.0. Typical users are analytics engineers and data teams who want to share data with stakeholders or feed it into AI agents without building a service from scratch; documentation is at vulcansql.com.
