MongoDB Query Builder

• Free online MongoDB query builder — works right in your browser, no installation needed
• Build queries through a visual interface with comparison operators ($eq, $gt, etc.), logical combinations ($and/$or/$nor), array operations ($in/$all), regex matching ($regex), field existence checks ($exists), and type checks ($type), generating MongoDB query statements automatically
• Preview query results against built-in sample data in real time, copy the generated JSON query with one click, and load or edit sample data easily

1. Open the tool page — no download or installation required
2. In the Query Builder, choose the logical relation (All Match / Any Match / None Match), then click "Add Condition" to set the field, operator, and value (enter one array value per line for array operators; regex supports options and case sensitivity)
3. The generated MongoDB query appears in the "Generated Query" panel on the right in real time, and matching sample data is shown in the "Query Result" panel automatically; click "Load Example" for a quick demo, or "Edit Data" to modify the sample data
4. Click "Copy" to copy the generated JSON query to your project with one click

• This tool is completely free and requires no registration or login
• All generation and querying happens locally in your browser — your data is never uploaded
• Query results are simulated in the browser against the built-in sample data, which must be a JSON array; adjust the field names and values to match your actual database
