Simon Willison introduces an interactive web-based tool that runs SQLite queries in the browser via Pyodide and annotates EXPLAIN output with plain-English descriptions. Inspired by Julia Evans' reflections on learning query plans, the tool aims to demystify SQLite's query planner and bytecode execution for developers.
Background
Understanding SQLite query plans is often difficult for developers due to the complexity of the EXPLAIN and EXPLAIN QUERY PLAN outputs. This tool leverages WebAssembly to bring server-side database analysis capabilities directly to the client side.
