+Run SQL queries against a SQLite database in your browser and see exactly how SQLite executes them: the tool runs your query, then annotates every line of both `EXPLAIN QUERY PLAN` and the low-level `EXPLAIN` bytecode output with plain-English descriptions of what the query planner and virtual machine are doing. Load the built-in example database — 170,000+ rows with indexes, a view and 22 example queries illustrating patterns like covering indexes, nested-loop joins, temp b-tree sorts, automatic indexes and recursive CTEs — or open your own SQLite file, which is inspected via `sqlite_master` to show its schema first. Bytecode instructions are cross-linked, so jump targets are clickable and hovering a register or cursor highlights everywhere else it is used. Powered by Python's `sqlite3` module running in Pyodide, so no data leaves your machine.
