Mock API Response Generator
Generate realistic mock API responses with custom schemas and random data
All processing happens in your browser. No data is sent to any server.
Why This Tool
Frontend developers and testers often need realistic API responses before the backend is ready. This tool generates mock JSON responses with realistic fake data based on a schema you define — names, emails, dates, IDs, and more.
How It Works
Define your response schema (field names, types, and optional constraints). The tool generates realistic sample data matching your schema. Copy the mock response or download it as JSON.
