Mock Data Factory

Describe your schema, get realistic fake data instantly

The Problem

Writing realistic mock data by hand is tedious and unrealistic

Current Solutions (Not Great)

Faker.js (limited), hand-write, copy from production (risky)

Who Needs This

Frontend devs, API developers, testers

Describe your data in plain English or paste a JSON schema, and get hundreds of realistic, contextually-aware mock records. Emails match names, dates make sense. Export as JSON, CSV, or SQL inserts.

Honest Take

Useful developer tool but Faker.js covers most cases. The AI advantage is contextual awareness (matching emails to names, realistic addresses) which Faker doesn't do well. Good as a quick web tool. Monetization is tricky since devs expect free tools. Consider a VS Code extension or CLI integration for better adoption.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Mock Data Factory' using WebInfer for AI inference. UI: input area accepts either plain English ('users with name, email, and signup date') or JSON schema. Use generateObject to create realistic mock data matching the schema. Options panel: number of records (1-100), locale (US, UK, EU, etc.), output format (JSON, CSV, SQL INSERT, TypeScript types). For large batches, use streaming with progress indicator. Generated data should be contextually realistic (e.g., email matches name, dates are sensible). Preview table view with syntax-highlighted code view toggle. Copy and download buttons. Save schemas as templates for reuse (localStorage). 'Generate related data' for foreign key relationships (e.g., users and their orders).
