**Tool:** [SQLite Query Explainer](https://tools.simonwillison.net/sqlite-query-explainer)
Julia Evan's, in [Learning a few things about running SQLite](https://jvns.ca/blog/2026/07/17/learning-about-running-sqlite/):
Maybe one day I’ll learn to read a query plan.
Big same.... which inspired me to have Fable build this interactive explain tool, which runs SQLite in Python in Pyodide in Web Assembly in the browser and adds a layer of explanation to the results of both EXPLAIN and EXPLAIN QUERY PLAN.
Approach with caution, since I don't know enough about SQLite query plans to verify the results myself, but it seems cromulent enough to me.
