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?
