About this Tool
Create rapid bulk fake payloads of user databases for unit testing.
1The Importance of Realistic Mock Data
Building and testing modern applications requires realistic data that mimics production environments without exposing actual user information. Our generator creates high-quality, randomized datasets including names, emails, addresses, and job titles to help you build better prototypes.
2Example: User Profiles
Generate 50 users with names like "John Smith" and emails like "john.smith@example.org" instantly in JSON, CSV, or SQL format.
3Seeding Databases and UI Testing
Whether you're seeding a local database for development or performing stress tests on your UI components, our generator provides consistent, valid data structures. You can customize the schema to match your specific requirements and export the results in various formats.
4Privacy: Local Data Synthesis
Generating datasets for a private internal project? Our synthesis engine runs 100% in your browser. No data is generated on a server, ensuring that your application's internal schemas and the scale of your testing remain completely confidential.
Privacy Guarantee
Secure Devutils operates exclusively in your browser using local web workers and JavaScript. Your source code, configurations, and sensitive text payloads are never transmitted across the network or stored on any external servers. It is completely safe for air-gapped environments.
