What is a SQLite file?

SQLite is a self-contained relational database stored as a single file. It powers iOS, Android, Firefox, Chrome, in-flight entertainment systems, and uncountable desktop apps. Extensions you'll see in the wild: .db, .sqlite, .sqlite3, .db3.

Can I run arbitrary SQL against my database?

Yes — sql.js ships the full SQLite engine compiled to WebAssembly. SELECT, JOIN, CTEs, window functions, JSON1, FTS, math functions: all of it works. Hit Cmd/Ctrl+Enter in the query box to execute.

No. The database is loaded into a WASM heap inside your tab. Nothing leaves your device. Closing the page discards the in-memory copy.

Why are some rows shown as '[N bytes blob]'?

SQLite columns can hold raw BLOB data (images, encrypted payloads). We summarize them by byte length instead of dumping unprintable bytes into the cell.

Does it work on mobile?

Yes. The schema panel collapses above the query editor on small viewports, and the results table scrolls horizontally with a sticky row index.

About SQLite

.db / .sqlite database file.

SQLite is the database that's everywhere — browsers, phones, planes, satellites. sql.js compiles the canonical SQLite engine to WebAssembly so you get a real query planner running entirely inside the tab. Drop in a .db, .sqlite or .sqlite3 file: we enumerate user tables from sqlite_master, count rows on each, and open the first table for inspection. Edit the query box, hit Run (or Cmd/Ctrl+Enter) and execute arbitrary SELECTs against your database. Results render in the editorial table chrome and export to CSV. BLOB columns are summarized by byte length so the viewport stays sharp on mobile.
