  description: 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.
