MockAPI.io is the easiest way for developers to create mock REST APIs by defining simple data models and resource relations, generating realistic fake data on the fly.

---

🚀 Overview

MockAPI.io is a no-code service that allows developers to quickly set up mock REST APIs without needing to build or deploy a real backend. Users define resources with simple schemas and data generators powered by Faker.js, establish relations between resources, and the platform automatically generates endpoints, supports CRUD operations, pagination, sorting, filtering, and more.

It solves the problem of backend dependencies during frontend development, API testing, prototyping, and learning by providing instant, realistic mock data via a RESTful interface. This accelerates development workflows and enables independent testing.

Built for frontend developers, full-stack teams, indie makers, and students who need fast API simulations. The project was created to simplify mocking REST APIs, making it accessible with minimal setup—no coding required for basic use.

✨ Key Features

• Simple data modeling: Define resource schemas and use Faker.js generators (e.g., name.fullName, image.avatar, date.recent) for realistic fake data.
• Automatic endpoints from relations: Link resources (e.g., users to posts) to auto-generate nested endpoints like /users/{userId}/posts.
• Advanced querying: Built-in support for pagination, sorting, filtering, and customizable responses.
• Collaboration: Share projects with teams (Pro plan). Upcoming: custom endpoints and webhooks.
