  DuckDB is an in-process, MIT-licensed analytical SQL database with no external
  dependencies. It runs as a library embedded in the host application (CLI, Python,
  Node.js, R, Java/JDBC, Go, Wasm, etc.) and does not expose a network REST API.

      DuckDB ships as a library with first-class bindings for Python, R, Java (JDBC),
      Node.js, C/C++, Go, Rust, Swift, Julia, and the browser via DuckDB-Wasm. There is
      no network REST API; clients call DuckDB in-process. Extensions like httpfs allow
      DuckDB itself to act as an HTTP/S3 client.
