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…

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…

I built a Chrome extension that acts as a WebSocket proxy, allowing real-time monitoring, message simulation, and traffic interception. Think "Proxyman for WebSockets" but integrated into Chrome DevTools. Key features: Real-time WebSocket monitoring and message capture Send custom messages in both directions (client ↔ server) Block incoming/outgoing messages for testing Background monitoring (captures connections even when DevTools is closed) Why: I was debugging a WebSocket chat app and needed better tools than browser DevTools. Existing solutions required external proxies or were too…

A simple Go-based HTTP proxy designed for detailed inspection of requests and responses. It logs traffic to the console with colorization, automatic decompression, and formatting for common content types, while remaining transparent to the client application. Ideal for debugging API interactions, understanding middleware behavior, or simply getting a clear view of HTTP traffic flow with jq-like pretty-printing & colorization of request/response. Automatically redacts parts of Authorization header to avoid token leakage.

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.…
