What is DB Fiddle?
DB Fiddle is an online SQL playground for experimenting with SQLite, PostgreSQL, and DuckDB in a browser. Pick an engine, write schema and query cells in its notebook-style editor, run them, and inspect the returned results. The public app presents the databases directly in the browser, making it useful for a quick query experiment or a reproducible SQL example without local server configuration.
What stands out
A browser-based SQL notebook that runs SQLite, PostgreSQL, and DuckDB through WebAssembly, so users can write, execute, and inspect queries without configuring a server.
