Top 10 Fake CRUD APIs for Testing and Building Frontend Applications
In the dynamic world of web development, having reliable and ready-to-use APIs is crucial for testing applications, especially during frontend development. Fake CRUD APIs simulate real-world API interactions, providing developers with a sandbox environment to test functionalities without setting up a backend. Below, we explore the top 10 fake CRUD APIs that are perfect for testing APIs and building frontend applications.
1. SimpleCRUDAPI.com
If you're searching for a robust, real-database-backed API that supports advanced validation and real-time data insertion, SimpleCRUDAPI.com is your top choice. This platform is built to provide a seamless testing experience with real-world functionality, including the ability to validate and insert data into a database.
Key Features:
- Full CRUD Support: List, create, show, edit, and delete resources with ease.
- Validation Rules: Enforce data validation rules similar to those found in production-ready APIs.
- Real Database: Unlike many fake APIs, SimpleCRUDAPI works with real database interactions, making testing more realistic.
- Fast and Reliable: Optimized for speed, ensuring quick responses even with complex queries.
Example Usage:
The API is simple to use with fetch requests. Here’s an example of retrieving a single todo item:
fetch('https://simplecrudapi.com/api/todos/1')

.then(json => console.log(json))
.catch(error => console.error(error));
Whether you're building a React app, testing Vue components, or integrating with Tailwind, SimpleCRUDAPI offers a professional-grade environment for developers to test their projects effectively.
2. JSONPlaceholder
JSONPlaceholder is one of the most popular fake APIs among developers. It mimics a complete RESTful service, allowing you to test CRUD operations. With resources like posts, comments, todos, and users, JSONPlaceholder is versatile and supports a wide range of use cases.
Example Resources:
-
https://jsonplaceholder.typicode.com/posts -
https://jsonplaceholder.typicode.com/users
Why Use It?
- Zero setup: Plug and play API.
- Highly scalable for testing large datasets.
- Supports real-time response simulation.
Example Usage:
fetch('https://jsonplaceholder.typicode.com/posts/1')
.then(response => response.json())
.then(data => console.log(data));
3. MockAPI
MockAPI stands out as a customizable tool for generating fake APIs. You can define your schema, configure response types, and even set up delays to mimic real-world API latency.
Key Features:
- Create nested resources for more realistic data structures.
- Supports RESTful operations.
- Provides UI for easy API setup.
Example:
fetch('https://mockapi.io/projects/12345/resource')
.then(response => response.json())
.then(data => console.log(data));
4. Reqres.in
Reqres.in is ideal for testing authentication, user management, and basic RESTful operations. It supports static and dynamic responses, making it a great choice for frontend developers who want to test user flows like login and signup.
Use Cases:
- Mock user data for frontend testing.
- Simulate API errors for robust error handling.
Example Usage:
fetch('https://reqres.in/api/users/2')
.then(response => response.json())
.then(data => console.log(data));
5. FakeREST
For developers looking for more control over their fake APIs, FakeREST is a fantastic tool. It allows you to generate fake APIs from a JSON file or create one from scratch using their intuitive editor.
Key Features:
- Ability to host your fake API locally or in the cloud.
- Customizable endpoints and responses.
Example Usage:
fetch('https://fakerestapi.azurewebsites.net/api/v1/Books')
.then(response => response.json())
.then(data => console.log(data));
6. DummyJSON
DummyJSON provides an extensive collection of resources, including products, users, and posts. It is particularly useful for testing eCommerce applications and dynamic dashboards.
Highlights:
- Predefined datasets for faster prototyping.
- Supports real-time data manipulation.
Example:
fetch('https://dummyjson.com/products/1')
.then(response => response.json())
.then(data => console.log(data));
7. Faker.js API
Faker.js is a JavaScript library for generating fake data, but its API offering takes it to the next level. The Faker.js API can simulate realistic names, addresses, and even payment details.
Why Use It?
- Ideal for testing form validations.
- Generates dynamic, human-like data for demos.
Example:
fetch('https://fakerapi.it/api/v1/users')
.then(response => response.json())
.then(data => console.log(data));
8. TypiCode Fake Store API
If you're developing an eCommerce site, the TypiCode Fake Store API is tailored for you. It provides a dataset of products, categories, and carts that mimic a real-world online store.
Features:
- Simulates product filtering and sorting.
- Includes cart and checkout flows.
Example Usage:
fetch('https://fakestoreapi.com/products')
.then(response => response.json())
.then(data => console.log(data));
9. Mockaroo
Mockaroo is a comprehensive API simulation tool that lets you create custom datasets. It’s particularly powerful for developers who need specific data structures for testing.
Features:
- Rich data type support (e.g., names, dates, and custom fields).
- On-demand dataset generation.
Example:
fetch('https://api.mockaroo.com/api/dataset?key=YOUR_API_KEY')
.then(response => response.json())
.then(data => console.log(data));
10. Beeceptor
Beeceptor is a fake API and request bin combined. It not only provides you with mock endpoints but also lets you inspect incoming requests, making it a great tool for debugging.
Key Features:
- Real-time request logging.
