Sharing an internal tool that accelerated my development work 10-fold, especially with API debugging. Thought fellow developers here might find it useful. As a developer, I often have trouble reproducing errors at the client end. https://intercept.rest lets me debug and monitor API requests and responses. It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined. Been a long time lurker here and…

Hey HN! We’ve open-sourced Requestly (https://github.com/requestly/requestly) - A network debugging proxy for web & mobile apps. Requestly intercepts all HTTP(s) requests & responses and provides full control to developers to modify the request/response like rewriting request URL to hit different environment or returning different response for APIs/scripts. In addition to HTTP(s) interception & modification capabilities, Requestly also offers Mock Server [0] & recording the browser sessions [1] with video, console logs, & network logs stitched together. We use…

Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…

Hi HN, I built this after using Requestly, Mokku, Mockiato, Tweak, and Mockoon. Each one either paywalled the features I actually needed, required a separate server running on my machine, or just didn't fit the way I work. The browser is already open. DevTools is already open. I wanted the mocking to live there too, not in a separate app I have to remember to start. So roughly a month ago, I started building my own tools. It intercepts network requests at the browser level and lets you swap the response, status code, headers, body without touching your code or spinning up anything.…

Hey HN, I recently built an open-source HTTP interceptor called Relay, which works as a Chrome extension for capturing, modifying, and replaying HTTP requests directly in your browser — no account needed. How it works: Relay lets you capture requests as they happen, modify parameters, headers, or body content, and replay them on the fly. You can customize or debug network requests quickly without needing an external tool or complex setup. Key features: - Simple setup: Install the extension and start a session to capture requests. You can filter by URLs and methods. -Request modification:…
