Pagewalk
Watch SQLite read its own file, page by page.
How it's built
- Official SQLite WASM in a worker, traced page by page
- Own file-format parser checked against the engine
- Page inspector, bytecode, query plan, writes and splits
- Index Golf: daily puzzle scored by a build-time table
- Lighthouse 1/1/1/1 on the landing page
The official SQLite WASM engine runs your query on a traced in-memory file and draws every page it touches on a map, with a read head, seek trail and B-tree view. Open the file's own bytes (header, hex, bytecode, query plan), split pages in writes mode, then play Index Golf: a daily puzzle where one CREATE INDEX must read the fewest pages, scored by the server from a table computed at build time.
