Deploy and Host Instant mock data API on Railway

Instant Mock Data API is a lightweight, production-ready service for generating fake data on demand. It lets you request exactly the fields you want (for example: firstName, email, latitude) or use presets (user, company, product). It returns JSON by default with optional CSV output, deterministic seeding, and response field filtering.

About Hosting Instant mock data API

This is a Node.js + Express app using Faker to synthesize realistic but fake data at runtime.

Deploy it directly from GitHub on Railway.

Configure environment variables for rate limits and item caps, or disable limits entirely for personal use.

The API is stateless and requires no database or API keys.

Railway handles builds, HTTPS, logs, region, and scaling.

For monorepos, set the Root Directory to the app folder (e.g., mock-data-api).

After deployment, you’ll have instant endpoints like /generate, /user, and /healthz for integration and testing.

Common Use Cases

Frontend prototyping: Build and demo UIs without a backend.

Testing/CI: Seed predictable fake data with ?seed= for automated tests.

Data samples: Produce CSV/JSON examples without handling real PII.
