What is a Browser-Based SQLite Viewer?
A browser-based SQLite viewer lets you open, browse, and query SQLite database files (.sqlite, .db, .sqlite3) directly in your web browser without installing any software. Using WebAssembly-compiled SQLite (sql.js), our viewer runs the full SQLite engine in your browser. You can browse tables, view schemas, run custom SQL queries, and export results. Your database files are never uploaded to any server — everything runs locally.

Frequently Asked Questions
How does it work without uploading my database?
We use sql.js, which is SQLite compiled to WebAssembly. The SQLite engine runs entirely in your browser. When you select a file, it is read into browser memory using the File API — no network request is made.
What is the maximum file size supported?
File size is limited by your browser's available memory. Most modern browsers handle databases up to 100-200MB comfortably. For very large databases, a native SQLite client is recommended.
Can I modify the database?
You can run INSERT, UPDATE, and DELETE queries. However, changes exist only in browser memory and are not saved back to the original file unless you explicitly export the modified database.
Why Use DevDeck?
Traditional SQLite viewers require installing desktop software. DevDeck runs SQLite in your browser via WebAssembly — zero installation, zero uploads, complete privacy for your database files.
