A powerful, privacy-focused, browser-based SQLite database management tool that runs entirely client-side with no server dependencies. Build, manage, and export SQLite databases directly in your web browser with complete data privacy and security.

Demo: https://xsukax.github.io/xsukax-SQLite-Database-Builder

xsukax SQLite Database Builder is a comprehensive web application designed for database developers, students, and professionals who need a quick, secure, and efficient way to create and manage SQLite databases. Built with vanilla JavaScript and powered by sql.js (a WebAssembly port of SQLite), this tool provides a full-featured database management interface without requiring any backend infrastructure or database server installation.

The application offers an intuitive user interface for creating table structures, inserting data, browsing records, executing custom SQL queries, and importing/exporting database files—all within the browser environment. Its zero-installation approach makes it ideal for rapid prototyping, educational purposes, data analysis, and situations where traditional database management tools are unavailable or impractical.

This application prioritizes user security and data privacy through its architectural design and implementation choices:

• Complete Client-Side Processing: All database operations execute entirely within the user's browser using WebAssembly technology. No data is ever transmitted to external servers, ensuring absolute privacy and eliminating network-based security vulnerabilities.

• Zero Data Collection: The application does not collect, store, or transmit any user data, analytics, or telemetry. Your database content, queries, and activities remain strictly confidential and never leave your local environment.

• No Server Dependencies: Without backend infrastructure, there are no server-side vulnerabilities, database breaches, or unauthorized access risks. Users maintain complete control over their data at all times.

• Local Storage Only: Databases exist exclusively in browser memory until explicitly exported by the user. This ephemeral approach prevents unintended data persistence and reduces exposure to browser-based attacks.

• Open Source Transparency: The entire codebase is publicly available for audit, ensuring transparency and allowing security researchers to verify the absence of malicious code or hidden data collection mechanisms.

• SQL Injection Prevention: User inputs are properly escaped and parameterized in critical operations, reducing the risk of SQL injection vulnerabilities within the client-side environment.

• No Authentication Required: The absence of user accounts, login systems, or authentication mechanisms eliminates password-related security concerns and reduces the attack surface.

• Intuitive Table Creation: Visual interface for defining table schemas with support for all SQLite data types (TEXT, INTEGER, REAL, BLOB)
• Advanced Column Constraints: Configure PRIMARY KEY, AUTOINCREMENT, NOT NULL, UNIQUE, and DEFAULT values through simple checkboxes
• Data Management: Insert, browse, and manage records with user-friendly forms and tabular views
• SQL Query Execution: Direct SQL query interface with syntax templates for SELECT, INSERT, UPDATE, and DELETE operations
• Database Import/Export:
  • Import existing SQLite database files (.db, .sqlite, .sqlite3)
  • Export databases as binary .db files
  • Export complete SQL scripts for portability and version control
• Real-Time Statistics: View table counts, row counts, and database size information
• Responsive Design: Mobile-friendly interface built with Tailwind CSS

• Zero Installation: No software downloads, installations, or system configurations required—just open the browser and start building
• Cross-Platform Compatibility: Works on any modern browser (Chrome, Firefox, Safari, Edge) across Windows, macOS, Linux, iOS, and Android
• Offline Capability: Once loaded, the application functions without internet connectivity, making it ideal for air-gapped or restricted environments
• Educational Value: Perfect for learning SQL and database concepts without the complexity of traditional database server setup
• Rapid Prototyping: Quickly design and test database schemas before implementing them in production environments
• Lightweight: Single HTML file weighing under 50KB (excluding external libraries) ensures fast loading and minimal resource consumption
• No Vendor Lock-In: Export databases to standard SQLite format compatible with virtually all programming languages and platforms

1. Navigate to the Structure tab (default view)
2. Enter a table name in the "Table Name" field (e.g., users, products, orders)
3. Click "+ Add Column" to add column definitions
4. For each column, specify:
   • Column Name: Identifier for the field (e.g., id, username, email)
   • Data Type: Select from TEXT, INTEGER, REAL, or BLOB
   • Default Value: Optional default value for the column
   • Constraints: Check applicable options:
     • PK: Primary Key (unique identifier)
     • NOT NULL: Require a value
     • UNIQUE: Ensure uniqueness across all rows
     • AI: Auto-increment (for integer primary keys)
5. Click "Create Table" to execute the schema

Example: Creating a users table with id (INT, PK, AI), username (TEXT, NOT NULL, UNIQUE), and email (TEXT).

1. Switch to the Insert Data tab
2. Select your target table from the dropdown menu
3. Fill in the form fields with your data values
4. Click "Insert Data" to add the record
5. Repeat for additional records

Note: Auto-increment primary key fields are automatically excluded from the insert form.

1. Navigate to the Browse Data tab
2. Select a table from the dropdown
3. View all records in a formatted table
4. NULL values are displayed with visual indicators

• Test Queries: Use the SQL Query tab to test complex queries before implementing them in code
• Regular Exports: Periodically export your database to avoid data loss (browser memory is volatile)
• Schema Planning: Design your table structure carefully—altering tables requires SQL knowledge
• Browser Console: Open browser DevTools to monitor for any errors or warnings
