Which file types can I open?

Any SQLite 3 database: .db, .sqlite, .sqlite3, .db3, and extensionless SQLite files. That covers Django, Rails, Laravel and Expo dev databases, Chrome/Firefox profile databases, iOS and Android app databases, Signal/WhatsApp exports, Fossil repos and countless desktop apps that store their data in SQLite.

Can I run any SQL, or just SELECT?

Any SQL SQLite understands — SELECT, JOIN, GROUP BY, CTEs, window functions, PRAGMA, and writes like INSERT, UPDATE, DELETE, CREATE TABLE. Writes apply to the in-memory copy; click “Save .db” to download the modified database. Your original file on disk is never touched.

How do I export query results to CSV?

Run your query and click CSV. You get a properly escaped, Excel-friendly CSV of exactly the rows the query returned — no need to install the sqlite3 CLI and remember .mode csv. There's a JSON export too.

How big a database can it handle?

Free users can open databases up to 10 MB and see 500 result rows per query. Pro removes the file-size cap (you're then limited only by your device's RAM, since the file is held in memory) and shows up to 5,000 rows per query.

Does it work offline?

Once the page and the WebAssembly engine have loaded, yes — everything runs locally. That makes it usable on an air-gapped laptop or when reviewing a client database you're not allowed to send anywhere.

How is this different from DB Browser for SQLite?

It's the same idea without the install. DB Browser is a great desktop app, but on a locked-down work machine, a colleague's laptop, or a Chromebook you often can't install anything. This runs in a tab and gives you the essentials: schema, row counts, ad-hoc SQL and CSV export.

What happens to BLOB columns?

They're shown as a size placeholder rather than dumped as binary noise, so wide tables stay readable. In CSV and JSON exports they're written the same way.

Open and query a SQLite database

Open any SQLite database (.db, .sqlite, .sqlite3) in your browser, browse tables, run SQL queries and export results to CSV or JSON. No install, no upload.

Drop a SQLite database here

.db, .sqlite, .sqlite3, .db3 — opened locally, never uploaded

Free plan: databases up to 10.00 MB and 500 result rows. Pro removes both limits.

What people use it for

Inspect a Django, Rails or Laravel dev database without installing the sqlite3 CLI.
Open an app's .sqlite file from a phone backup and read the tables inside.
Run an ad-hoc SQL query against a client database on a machine where you can't install software.
Export a single table — or a filtered query — straight to CSV for Excel or Google Sheets.
Check a schema, column types and row counts before writing a migration.
Look inside a Chrome or Firefox profile database (history, cookies, local storage) to debug something.
Quickly verify that a database dump you received actually contains the rows you expected.

This free online SQLite browser lets you open a .db file and run SQL queries in your browser — no install, no signup, and no upload. Drop in any SQLite database (.db, .sqlite, .sqlite3, .db3) and you immediately get the table list with row counts, the column names and types, and an editor where you can run any query SQLite supports.

It's the fastest way to view a SQLite database online when you can't install DB Browser for SQLite, DBeaver or the sqlite3 command line — a locked-down work laptop, a Chromebook, or someone else's machine. Because a full SQLite engine is compiled to WebAssembly and runs inside the tab, your file is read from disk and never leaves your device, so it's safe for production dumps, customer tables and anything else covered by an NDA or GDPR.

Beyond browsing, you can convert SQLite to CSV or JSON in one click: write a SELECT, filter and join however you like, then download exactly those rows for Excel, Google Sheets or a data pipeline. Writes work too — run UPDATE, INSERT or CREATE TABLE against the in-memory copy and save a modified .db file back to your computer, leaving the original untouched.

How it works

1
Open your database
Drag in a .db, .sqlite or .sqlite3 file. It's read locally into a WebAssembly SQLite engine — nothing is uploaded.
2
Browse or query
Click a table to preview its rows, or write your own SQL and hit Ctrl/⌘ + Enter. Errors come back with SQLite's exact message.
3
Export the results
Download the current result set as CSV or JSON, or save the whole database back out as a .db file if you changed anything.

Frequently asked questions

No. The tool loads a real SQLite engine (SQLite compiled to WebAssembly) inside your browser tab and opens the file straight from your disk. Nothing is sent to a server, which is the whole point — production database dumps usually contain customer data you must not paste into a random online viewer.
