Yes! MockerAPI is 100% free with no hidden costs, no credit card required, and no usage limits. We believe in providing free tools for developers.
No signup required! Start testing HTTP status codes or creating mock API endpoints immediately without any registration or authentication.
All standard HTTP status codes from 100 to 599 are supported, including 200 (OK), 201 (Created), 400 (Bad Request), 401 (Unauthorized), 403 (Forbidden), 404 (Not Found), 500 (Internal Server Error), and many more.
MockerAPI is designed for development, testing, and prototyping. While our infrastructure is reliable and powered by Cloudflare's global CDN, we recommend using your own production APIs for live applications.
When creating a mock endpoint, choose from Bearer Token, API Key Header, or Basic Auth. We auto-generate secure tokens for you. Your endpoint will require the authentication header to respond successfully.
Yes! Add a delay parameter (0-60000 milliseconds) to test timeout handling, loading states, and slow network conditions in your applications.
Yes! All MockerAPI endpoints have CORS enabled by default, allowing you to make requests from any domain including localhost, perfect for frontend development.
Mock endpoints are persistent and remain active indefinitely. However, we recommend saving your endpoint URLs as we may implement retention policies in the future.
MockerAPI is a comprehensive HTTP mocking and testing platform designed for modern web developers. Whether you're building a REST API client, testing error handling, or prototyping a new application, MockerAPI provides the tools you need to test HTTP requests and responses without setting up complex backend infrastructure.
Our HTTP Status Code Tester lets you instantly test any status code from informational responses (1xx) to server errors (5xx). Test 200 OK responses, 404 Not Found errors, 500 Internal Server Error conditions, and everything in between. Add custom delays to simulate slow networks and test your timeout handling.
The Mock API Generator creates custom REST API endpoints with your own JSON responses, authentication requirements, and HTTP methods. Support for GET, POST, PUT, DELETE, and PATCH requests makes it perfect for full CRUD application testing. Add Bearer token authentication, API key validation, or Basic Auth to test your authentication flows.
Our HTTP Tester is a powerful httpbin.org alternative that provides 10 inspection endpoints for debugging HTTP requests. Inspect GET, POST, PUT, PATCH, and DELETE requests with full header and query parameter visibility. Test Basic Auth and Bearer token authentication flows, simulate delays, and test any HTTP status code. Perfect for debugging client applications and understanding how your HTTP requests are structured.
Built on Cloudflare Workers and distributed globally via CDN, MockerAPI delivers fast response times from anywhere in the world. All endpoints support CORS by default, making cross-origin requests from your localhost or staging environments seamless.
Perfect for frontend developers who need mock backend APIs, QA engineers testing edge cases, educators teaching HTTP and REST concepts, and API developers prototyping new endpoints. No registration, no API keys, no credit card - just free HTTP mocking tools that work instantly.
Whether you're using curl, Postman, Insomnia, fetch API, axios, or any HTTP client library in Python, JavaScript, Go, Ruby, or PHP - MockerAPI works seamlessly with your development workflow.
