QStudio is a free, modern SQL editor supporting over 30 databases, including MySQL, PostgreSQL, and DuckDB. It offers features such as server browsing for easy viewing of tables, variables, functions, and configuration settings; SQL syntax highlighting; code completion; the ability to query servers directly from the editor; and built-in charts for data visualization. QStudio runs on Windows, Mac, and Linux, providing particularly good support for kdb+, Parquet, PRQL, and DuckDB. Additional functionalities include data pivoting similar to Excel, exporting data to Excel or CSV, and AI-powered tools like Text2SQL for generating queries from plain English, Explain-My-Query for code walkthroughs, and Explain-My-Error for debugging assistance. Simply send the query you want and select the chart type to draw a chart. Send queries straight from within the editor to any of your servers. All data structures are handled perfectly.
