A Full Database in Your Browser

Sometimes you just need to test a complex JOIN or window function. Instead of spinning up a Docker container, this tool boots a real SQLite engine (sql.js) locally via WebAssembly. Your data never leaves your machine.

How to use this tool

  1. Click 'Load Demo Data' to populate the database with a sample table.
  2. Write standard SQLite queries in the editor.
  3. Click 'Run Query' to view the results in the table below.

Frequently Asked Questions

Is the data saved when I refresh the page?
No, the database runs in memory. If you refresh, all data is lost. Make sure to export your DB if you want to keep it.
Can I load an existing database?
Yes, use the Import DB feature to load an existing .sqlite file into the WASM engine.
