Mock API Generator

The Mock API Generator creates JSONPlaceholder-style responses for frontend development, API client demos, tutorials, and UI states. Instead of waiting for a backend, you can generate realistic posts, users, products, comments, success responses, and error payloads that look like the APIs frontend code usually consumes.

This tool is useful when designing list screens, cards, dashboards, loading states, empty states, and API client examples. Choose a resource, select a response type, set item count or status code, then copy the JSON into your app, tests, documentation, or API Playground request examples.

Everything is generated locally in the browser. The endpoint labels are intentionally mock URLs so you can document how routes should look without pretending to host a real public API. Use it for prototypes, teaching REST concepts, testing response shapes, and preparing fake data before a production API exists.
