the DuckDB IDE for Your Terminal. The SQL IDE for Your Terminal. Now with hsql, your agent's favorite sql client. I built this because I work in Data, and I found myself often reaching for the DuckDB CLI to quickly query CSV or Parquet data, but then hitting a wall when using the DuckDB CLI as my queries got more complex and my result sets got larger.
