A full SQLite workbench that never sees your data.
From a file to a query in three steps.
No install, no sign-up, no server. Everything below happens in your browser tab.
- 01
Open or create a database
Drag in a .db / .sqlite / .sqlite3 file, click “New database” for a blank one, or load the sample to see it in action. Your file is read locally and never leaves the tab.
- 02
Write and run SQL
Type a query in the editor — autocomplete suggests tables and columns from the live schema. Hit Run (or ⌘↵) and results stream back from the Web Worker without freezing the page.
- 03
Inspect, refine, export
Browse tables in the sidebar, preview rows and schema, tweak your query, then export the database to a .db file. Your work also auto-saves on-device, so a refresh never loses it — everything stays on your device the whole time.
The desktop SQLite client, without the desktop.
Everything you expect from DB Browser for SQLite or the sqlite3 shell — plus a privacy model those tools can't offer, because there is no server in the loop.
On-device engine, on-disk storage
The official SQLite WebAssembly build (sqlite3-wasm) runs in a background Web Worker, and your database lives on-device in the Origin Private File System — so it survives refresh and reload. Nothing of yours is sent to a server: not your database, not your queries, not your results. Inspect the Network tab for zero egress, and note the engine is self-hosted with no third-party CDN.
A real SQL editor
CodeMirror with SQLite syntax highlighting, schema-aware autocomplete (tables and columns suggest as you type), multiple statements, ⌘↵ to run, and a library of starter templates.
Browse, edit, export
Click any table to preview its rows and schema, then double-click a cell to edit it inline, add or delete rows, and sort or filter — no SQL required. Ask the built-in AI to write SQL from plain English, load a database straight from a URL, and export the whole table or any query to CSV.
CSV in, SQLite out
Drop a CSV and it becomes a typed SQLite table in one click — headers become columns, types are inferred, and you can import a whole folder on Pro. Turn spreadsheets into queryable databases instantly.
OPFS on-disk persistence
Your database is written straight to the browser's Origin Private File System through the official sqlite3-wasm SAH pool, so edits survive refresh and reload automatically. No manual save, no re-upload, and no COOP/COEP headers required — close the tab, come back tomorrow, and your work is still there.
The core editor is free forever — open files, run unlimited queries, import CSV, and export your database. Pro removes the convenience limits for people who live in their databases.
- Open larger databases — lift the free file ceiling
- Batch CSV import: drop a whole folder at once
- Unlimited browser workspaces & saved scripts
- Export your full query history
