Meet Request Interceptor Pro: the ultimate in-browser tool to pause, inspect, and modify HTTP requests on the fly. Built for developers and security researchers, it replaces bulky desktop proxies with a lightweight Chrome extension. Seamlessly intercept traffic, tweak headers and POST bodies, drop unwanted requests, or clone and replay them with a single click. Featuring a clean dark UI and Manifest V3 support, debugging web apps has never been faster. Take control of your network traffic!

I’m Rocco, the maker of Request Interceptor Pro. I'm super excited to share this with you all today! The Problem: As a developer, I constantly found myself needing to quickly tweak a request header, modify a POST payload, or block a specific API call to see how the front-end handles errors. But booting up heavy desktop proxies (like Burp Suite or Charles) just for a quick 2-minute test always felt like overkill. The Solution: I built Request Interceptor Pro to scratch my own itch. It’s a lightweight, fully in-browser HTTP interceptor that gives you total control over your web traffic right inside Chrome. Best of all, it's fully built on the new Manifest V3 architecture, so it's fast and future-proof. Here’s what you can do with it: ⏸️ Intercept & Pause: Catch requests before they hit the server. ✏️ Modify on the Fly: Tweak URLs, headers, query parameters, and JSON/Form bodies. 🚫 Drop Traffic: Block specific requests to easily test front-end error handling. 🔄 Clone & Replay: Quickly copy an intercepted request, modify it, and send it again directly from the panel. 🌙 Dark UI: A clean, developer-focused interface that won't blind you during late-night debugging. I built this tool to speed up my daily workflow, and I really hope it saves you as much time as it saves me. I’ll be hanging out in the comments all day. I would love to hear your thoughts—what features would you like to see added next? Cheers, Rocco Why this works well on Product Hunt: It’s personal: Using your name (Rocco) and explaining your personal pain point makes the product highly relatable. It’s scannable: The bullet points with emojis make the core features very easy to read in just a few seconds. It drives engagement: Asking an open-ended question at the end ("what features would you like to see added next?") encourages users to comment, which boosts your ranking on the site. Would you like some tips on the best times and days to launch on Product Hunt?

Lightweight, local proxy that just works. Perfect for quick API debugging.

I used to launch heavy external proxy software every time I needed to test an API or alter a payload, but this extension has completely replaced them for my daily tasks. It turns your browser into a local debugging tool without any complicated setup or external dependencies.

What makes it way better than the alternatives:

Real-time interception and editing: It lets you pause outgoing HTTP/HTTPS traffic on the fly. You can quickly modify URLs, HTTP methods, headers, or body payloads before they actually hit the server, which is incredible for quick testing.
Smart request replayer: The built-in request builder is a massive time-saver. You can clone or forge requests directly inside the context of the active tab, meaning your session cookies and CORS rules are perfectly handled without extra configuration.
100% private and lightweight: At just around 24KiB, it has zero impact on browser performance. Since it uses the native Chrome Debugger API and processes everything locally, none of your data or intercepted payloads ever leave your machine.

It is an incredibly straightforward tool for developers and QA engineers who want to test application resilience without the fluff.
