# SQLite Query Explainer > Source: > Published: 2026-07-18 17:19:10+00:00 **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](https://github.com/simonw/tools/pull/299#issue-4919268017) 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.
