Free tool
Online database viewer
This free online DB viewer opens a SQLite database right in your browser. Drop in a .db or .sqlite file to browse its tables and run SQL queries instantly — no install, no account, and nothing is ever uploaded to a server.
Online database viewer
Open a SQLite database in your browser — browse tables, filter columns, and page through rows. Nothing is uploaded.
Drop a SQLite .db / .sqlite file, or click to browse
Your database is opened locally and never uploaded
Your database is opened entirely in your browser with sql.js (SQLite compiled to WebAssembly). The file is never uploaded, and browsing or filtering never changes the original file.
How to open a database file online
- Drop your file. Drag a SQLite
.db,.sqlite, or.sqlite3file onto the box above, or click to browse. - Browse the tables. Every table in the database appears as a button — click one to see its first rows.
- Run SQL. Edit the query box and click Run query to run any
SELECT(or other) statement against the database. - Explore safely. Queries run on an in-memory copy, so nothing you do changes the original file on disk.
What is a SQLite database?
SQLite is the most widely deployed database in the world — it powers phones, browsers, apps, and countless desktop programs. Instead of running a server, a whole SQLite database lives in a single file, usually ending in .db, .sqlite, or .sqlite3. That makes it perfect for shipping data inside an app, but it also means you normally need a desktop program to look inside one. This tool removes that step: it runs SQLite itself — compiled to WebAssembly with sql.js — directly in your browser, so you can open and query a database file anywhere, even on a locked-down work laptop.
Why view a database in the browser?
- Nothing to install. No DB Browser for SQLite, no command line, no admin rights — just open the page.
- Private by design. Your database is read locally and never uploaded, so customer data and app exports stay on your machine.
- Works anywhere. Any device with a modern browser can inspect a database — great for quick checks on the go.
- Real SQL. It's the actual SQLite engine, so your queries, joins, and functions behave exactly as they would in production.
Who uses an online database viewer?
- Developers inspecting an app's local database, a test fixture, or a data export.
- Data analysts peeking at a SQLite dataset before loading it into a bigger pipeline.
- Mobile engineers checking the SQLite file pulled from an iOS or Android app.
- Students learning SQL against a sample database without setting up a server.
- Support & QA reproducing an issue from a customer's database export.
Tips & limitations
- Table previews are capped for performance; add your own
LIMITandWHEREclauses to narrow results. - Edits and inserts run against the in-memory copy and are not written back to your file — this is a viewer, not a saver.
- Very large databases use more memory because the whole file is loaded into the tab; close other tabs if you hit a limit.
- Only SQLite files are supported. To view MySQL or Postgres data, export a table to SQLite or CSV first.
Frequently asked questions
- Is my database uploaded to a server?
- No. The file is opened entirely in your browser using sql.js (SQLite compiled to WebAssembly). It is never uploaded, stored, or logged, so your data stays completely private.
- Which file types can I open?
- Any SQLite database file — commonly .db, .sqlite, or .sqlite3. Files from apps, browsers, and SQLite exports all work.
- Can I run SQL queries?
- Yes. There's a query box where you can run SELECT statements (and joins, aggregates, and SQLite functions) against the database and see the results as a table.
- Will my queries change the original file?
- No. Queries run on an in-memory copy of the database, so the file on your disk is never modified. It's safe to explore.
- Is there a size limit?
- There's no fixed limit, but because the whole database loads into your browser's memory, very large files depend on how much RAM your device has.
- Can I open MySQL or PostgreSQL databases?
- Not directly — this tool reads SQLite files. To inspect MySQL or Postgres data here, export a table to SQLite or CSV and open that.
