Practical HTTP debugging notes for developers
Step-by-step guides, engineering write-ups, and comparison pieces on debugging API traffic, HTTPS interception, MCP workflows, and native macOS tooling.
Debugging in the AI Era: Inspect MCP, Agent, and Local LLM Traffic from One Native macOS App
The modern dev stack — AI agents, MCP servers, local LLMs, WebSockets, and Protobuf — is mostly debugged by guessing. Read the real bytes on macOS, in one open-source app, and hand them back to your AI assistant over MCP.
Looking for a Proxyman alternative?
This shorter comparison page is the direct answer if you are evaluating native macOS proxy tools side by side.
Advanced Flutter API Debugging on macOS with Rockxy
A production-style workflow for Flutter HTTPS, localhost, emulator/device routing, headers, mapping, blocking, latency, replay, and scripting.
How to Use Upstream Proxy and WebSocket Protobuf Decoding in Rockxy
Route Rockxy through an upstream HTTP or HTTPS proxy, configure bypass rules, and decode binary WebSocket Protobuf frames without a schema.
How to Debug Node.js API Requests on macOS
Start with one known localhost request, prove the proxy route in Rockxy, then move to axios, Node core, got, and HTTPS certificate trust.
How to Debug Python API Requests on macOS
Start with one known localhost request, prove the proxy route in Rockxy, then move to requests, httpx, aiohttp, urllib3, and HTTPS certificate trust.
How to Debug Flutter API Requests on macOS
The shortest path from "my Flutter app is timing out" to "I can see the real request, response, headers, and TLS behavior."
Debugging a Failing Stripe Webhook with Claude and Rockxy
A real debugging session using Rockxy capture plus MCP tools to isolate a failing Stripe webhook flow in minutes.
How to Connect Claude Desktop to Rockxy's MCP Server (3-Minute Setup)
A direct setup guide for connecting Claude Desktop to Rockxy so your assistant can inspect real captured traffic.
MCP Servers for API Debugging on macOS — A Developer's Shortlist
What matters when you want an assistant to inspect local traffic, and which kinds of tools actually hold up in a real workflow.
What Is an MCP Server? A Developer's Primer for 2026
A practical primer on MCP, why local tools fit stdio well, and how structured traffic access changes debugging workflows.
Charles Proxy Alternatives for macOS in 2026
A side-by-side look at the main HTTP debugging tools on macOS and the trade-offs that actually matter in day-to-day use.
How Rockxy Intercepts HTTPS Without Compromising Security
A technical walkthrough of certificate trust, per-host leaf certificates, and why local HTTPS interception does not need to be opaque.
Virtual-Scrolling 100k Network Requests in SwiftUI
Why Rockxy uses an AppKit bridge for very large flow lists, and what that buys in memory, smoothness, and responsiveness.
Charles Proxy vs Proxyman vs Rockxy
An honest breakdown of the three most common macOS HTTP debugging workflows: native UX, pricing, trust, and daily usability.
Why We Chose SwiftNIO Over Network.framework
A lower-level look at the networking stack choices behind Rockxy and why byte-level control mattered for a debugging proxy.
How to Debug HTTPS Traffic on macOS with a Local Proxy
The practical setup path for HTTPS interception on macOS: trust, TLS, and what you can actually inspect once the proxy is live.
Why We Built Rockxy
The origin story behind a native, open-source macOS proxy that treats local trust, source visibility, and developer ergonomics as first-class concerns.
