A tool for intercepting, modifying, and mocking HTTP requests and responses. Perfect for testing and debugging. NetMock: Powerful HTTP Request Interception and Mocking Tool for Developers NetMock is a professional development tool that empowers developers, QA engineers, and testers to intercept, modify, and mock HTTP requests and responses directly in the browser. Whether you're building frontend applications, testing APIs, or debugging network issues, NetMock provides the tools you need to work more efficiently without relying on external proxy servers or complex setup. Why NetMock? Modern web development requires constant interaction with APIs and backend services. However, during development, you often need to: - Test your application without a fully functional backend - Simulate different API responses and error scenarios - Debug network requests without modifying server code - Test edge cases and error handling - Develop offline-capable applications - Record and replay HTTP requests for consistent testing - NetMock solves all these challenges by giving you complete control over HTTP traffic in your browser, right where you need it. Key Features: 🔍 HTTP Request Interception NetMock intercepts all HTTP requests made by web pages before they reach the server. This allows you to see exactly what your application is sending and receiving, making debugging faster and more transparent. The extension works seamlessly with fetch API and XMLHttpRequest, covering all modern web applications. 🎭 Request and Response Mocking Create custom mock responses with any status code, headers, and body content. Mock responses are returned instantly, eliminating network latency and allowing you to test your application's behavior under various conditions. Perfect for simulating API responses, error scenarios, or testing with different data sets. 📹 Request Recording Record all HTTP requests made by a website and save them for later use. This feature is invaluable for creating mock rules based on real API calls, understanding application behavior, or documenting API interactions. Recorded requests can be easily converted into mock rules with a single click. 🎯 Site-Specific Activation NetMock only activates on websites you explicitly enable, ensuring it doesn't interfere with your normal browsing. This selective activation gives you precise control over when and where mocking occurs, making it safe to use while browsing the web. 💾 Advanced Rule Management Create, edit, and organize multiple HTTP rules with an intuitive interface. Each rule can match requests based on URL patterns, HTTP methods, and request headers. Rules can be activated or deactivated instantly, allowing you to test different scenarios quickly. Group rules by origin for better organization. 🔍 Real-Time Request Logging Monitor all intercepted requests in real-time with detailed information including URLs, methods, headers, request bodies, response status codes, and timing. The logging system helps you understand your application's network behavior and identify issues quickly. 👤 User Accounts and Authentication Secure user accounts with authentication ensure your rules and settings are safely stored and synchronized. Create an account to access premium features and manage your subscription. ⭐ Premium Features Upgrade to Premium for unlimited rules, sites, and ignored URLs. The free tier includes 10 rules, 5 enabled sites, and 5 ignored URLs - perfect for getting started. Premium subscribers get unlimited access to all features for just $2/month or $10/year. 🎁 Promo Codes Support for promotional codes allows you to unlock extended features or trial periods.

This is useful for excluding analytics, tracking pixels, or other third-party requests that aren't relevant to your testing. Use Cases: Frontend Development Develop and test frontend applications without waiting for backend APIs to be ready. Mock API responses to build UI components independently, test different data scenarios, and work offline. API Testing and Debugging Intercept and inspect API calls to understand request/response formats, debug authentication issues, and verify that your application sends correct data to the server. Error Scenario Testing Simulate various error conditions (400, 401, 403, 404, 500, etc.) to ensure your application handles errors gracefully. Test edge cases without modifying server code. Performance Testing Mock responses to eliminate network latency and test application performance under ideal conditions. This helps identify performance bottlenecks in your code rather than network issues. Offline Development Create mock responses for all API endpoints to develop and test applications that work offline or with limited connectivity. QA and Testing QA engineers can use NetMock to test applications with different API responses, simulate server errors, and verify error handling without requiring backend changes. API Documentation Record real API calls to document API interactions and understand how applications communicate with backend services.

ModResponse - Mock and replay API
Mock, modify, and replay API. Easy setup. No proxy needed. No code change required. ModResponse is a powerful and easy-to-use tool for web developers that simplifies the process of modifying, stubbing, and replaying HTTP responses. It requires no extra proxy or code change to be made, allowing you to quickly and conveniently test different scenarios and debug edge cases. With ModResponse, you can modify the API response, return different HTTP status code, add delay to your request, etc. You can also reroute your HTTP request to a different server, allowing you to test your local changes in production domain within seconds, without the risk of breaking production. ModResponse does not require extra proxy or making any code change. It can modify pretty much any HTTP request, not just XHR requests. Simply install it and you are ready to go! ** What can ModResponse do?** - Record and replay HTTP response - Stub HTTP response - Reroute request to a different URLs - Change HTTP response body, status code, and headers - Delay HTTP requests to simulate slow network - Simulate network errors - Advanced filtering by tab, tab group, window, or time - Demo with fake data Want to create perfect data for your product demo? With ModResponse, you can replace the actual API response with a fake one that contains the data you want. No need to change your real data or make code change. - Speed up slow requests Do you have API requests that are taking a long time to finish, and every time you make a small UI tweak you need to wait >10 seconds for the API request to finish to visualize your change? Using replay response, you can record and replay the slow API request. That way, you will only need to wait on the slow API request once. All subsequent requests to be served from the cached response within a few milliseconds. - Develop against edge cases Need to handle a 4XX or 5XX status code from an XHR request, or try out how your UI will behave with a very long string? Using replay response or stub response, you can modify the response body, status code, or response headers to simulate different scenarios that you need to handle. - Develop against unimplemented APIs Are you a web developer who is blocked because an endpoint you depend on is not yet implemented? Using stub response, you can mock the API response so you can start developing against that endpoint. That way, you can develop the frontend while others implement the endpoint (as long as the actual implementation return the response in the same format). - Testing on production domains Do you need to integrate with a third party platform that only works on your production domain? Using proxy request, you can reroute the request from your production domain to localhost or a dev domain, allowing you to test your changes on your production domain without the risk of breaking it. - Debug edge cases Need to test how your app behaves when some resources takes too long to load, or when they fail to load due to network errors? With ModResponse, you can add artificial delay and simulate different network error conditions so you can debug and handle edge cases with ease. ** Other ModResponse features ** - Support having multiple profiles with quick switching between profiles - Export and import profile - Easily share your profiles with others - Dark mode support - Customizable profile badge - Clone profile ...and more!!! "debugger" is required in order for response modification to work. "tabs" permission is required for prefilling the URLs, and for tab filter, tab group filter, and window filter to work. "storage" and "unlimitedStorage" are required to store the response modification. "contextMenus" is used to enable quick pause/unpause by right-clicking on the icon. ** Known issues ** 1, You will see ["ModResponse" started debugging this browser] banner when ModResponse is activated. This is because it uses the debugger API, which is needed for response modification. Due to Chrome's security policy (https://crbug.com/1096262), that banner would show up on all tabs even when a tab is not being modified, and it may still for a few more seconds after ModResponse is paused or disabled. To hide it, you can run chrome with --silent-debugger-extension-api command line switch. 2, Clicking on the "Cancel" button on the ["ModResponse" started debugging this browser] banner will not deactivate ModResponse. To deactivate it, please open ModResponse and click on the "Pause" button. Once paused, the banner should disappear in a few seconds.
