+short_description: Real SQL against DuckDB WASM — runs in your browser
 ---
+# SQL Query Playground
+Write and run **real SQL against a seeded warehouse** — DuckDB compiled to
+WebAssembly, executed entirely in your browser. Nothing is uploaded, no server
+exists: the database, the engine and the results all live on your machine.
+- **55 tested templates** — window functions, cohort queries, funnel metrics,
+  date arithmetic — every template is also executed in CI against the same data.
+- Schema browser for the four-table warehouse (1,000 customers, 5,000 orders,
+  12,663 line items), seeded deterministically.
+- Ctrl+Enter to run; query timing and row counts shown on every execution.
+Not a simulation: every query is parsed, typed and executed by a real DuckDB
+engine. Errors surface as data — the way production pipelines treat failures.
+- Code + template library: [sql-query-builder on GitHub](https://github.com/Reaver1000/sql-query-builder)
+- Built by [David Buchan](https://reaver1000.github.io) — AI, automation and data work
