Hi HN, I'm Tyler Flint. Eight months ago we shared qtap here (https://news.ycombinator.com/item?id=43928118). Today we're releasing DevTools - a browser-based interface that gives you the Chrome Network tab experience for server-side HTTP/S traffic. The problem: You're debugging a production issue. An external dependency is returning errors. Your logs say "request failed" but not what was actually sent. Adding debug logging means redeploying and restarting services - which takes time and often changes the conditions you're trying to debug. tcpdump shows encrypted blobs.…

BoringSSL and nghttp2. Matches JA3N, JA4, and JA4_R fingerprints. Supports HTTP/2, async/await, and works with Cloudflare-protected sites. Not trying to compete with curl_cffi - just a learning project that turned into something functional.

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…

I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…

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:…
