SQLite Query Explainer

Simon Willison's Weblog reports on a new interactive tool that explains SQLite query plans. Julia Evans once wished she understood how to read them, and it inspired Willison to build a browser-based explainer that runs entirely in WebAssembly.

It's not a verified expert tool, but it's useful for developers trying to understand their database performance.
