Mock API basics

What is a mock API?

A mock API is a fake backend that responds through real HTTP endpoints while your production backend is not ready yet. Mimicry gives frontend teams a hosted mock REST API with realistic JSON, dynamic Faker data, and shareable URLs that can be used by developers, QA, demos, and tests.

Fast setup

Create a mock REST API in seconds

Type a path, choose the response shape, and your mock endpoint is live. Use simple mocks for generated payloads or CRUD resources when you need persisted records, pagination, sorting, filtering, and relations without writing backend code.

Guide

When to use Mimicry instead of json-server, MSW, or Postman mocks

Use local tools when the mock only needs to run on one machine. Use Mimicry when the team needs a hosted mock API generator with a real URL, no local setup, API keys, realistic data, and behavior that can be shared across frontend, QA, mobile, CI, and product demos.

Tutorial

Test latency, errors, empty states, and realistic data

A useful mock API does more than return the happy path. Mimicry lets you simulate random latency, HTTP failures, empty data, malformed fields, and deterministic JSON so your frontend handles production-like conditions before production exists.
