SQLite is a self-contained relational database kept inside one file. You encounter it within smartphones, web browsers, and IoT firmware. Because no server runs, the format travels easily across systems. Despite the simplicity, it accepts standard SQL commands. Understanding its structure empowers you to inspect, debug, and migrate data quickly.

This manager lets you load any SQLite file directly in your browser, explore schemas, run queries, and export results. It removes the need for desktop clients or command-line tools. You keep full control while staying productive on any device. Session data never leaves your machine, guarding sensitive information at work.

You drag a database file onto the drop zone and the interface instantly lists tables, views, indexes, and triggers. Click a table to preview rows or write a query in the editor. Export CSV snapshots for reporting or share sanitized datasets with teammates. The workflow saves time during audits and bug hunts.

Files are processed locally in your browser; nothing is uploaded.

FAQ:

Find quick answers to common questions.

Does the tool work offline?

The interface loads required assets once. Afterwards you can inspect databases without an internet connection.

Is my data ever transmitted?

No. All processing occurs inside your browser sandbox; nothing leaves your computer.

How large a database can I open?

Performance remains smooth up to roughly 100 MB. Very large files may stress your device’s memory.

Can I edit and save records?

You can run INSERT, UPDATE, or DELETE statements. Use Export DB to download the modified file.

Does the editor support formatting?

Yes. Press Ctrl+B to beautify highlighted SQL for better readability.

Troubleshooting:

Resolve frequent issues quickly.

  • File fails to load: Confirm the extension is .db or .sqlite and size is below 100 MB.
  • Query freezes: Refresh the page to free memory, then run smaller statements.
  • Missing tables: Remove filter text; hidden items may match your search term.
  • CSV exports blank: Ensure your query returns rows before exporting.
  • Accidental edits: Click Undo in history to restore the previous state.
