What Makes This Online SQL Compiler Unique?

Line-by-Line Gutter Execution

Unlike standard tools where you must highlight text or run a whole multi-query file, SQLite Studio attaches a small circular ▶ button to every statement in the editor gutter. Click it to run that line instantly.

Interactive ER Diagram

Visualizing relationships between primary keys and foreign keys is effortless. An auto-updating diagram renders connected table cards with draggable layout and click-to-query shortcuts.

100% Private Client-Side Sandbox

Your queries and proprietary data are never transmitted to any third-party server. Everything executes locally in your browser memory and persists across refreshes using IndexedDB.

Pre-Loaded ERP Sample Data

Don't waste time typing CREATE TABLE and INSERT statements from scratch. We ship with a complete e-commerce/ERP database (`customers`, `suppliers`, `products`, `orders`, `order_items`) ready to query.

Start Writing SQL Queries in Seconds

Experience the full dual split-screen editor with sortable spreadsheet results, multi-tab query editing, and SQLite import/export.
