Httap – intercept and inspect HTTP traffic from your shell or agent
Multi-surface HTTP inspection (CLI, TUI, MCP, API) with project-scoped isolation is thoughtful.
Open-source MITM proxy to intercept, inspect, and mock network traffic.
Browser-based MITM proxy when mitmproxy and Proxyman already dominate this space.
Backend developers, API testers, QA engineers

Multi-surface HTTP inspection (CLI, TUI, MCP, API) with project-scoped isolation is thoughtful.
Three UIs (TUI, terminal, web) simplify MitM debugging, but mitmproxy and Burp already own this.
Built-in IPv6 NDP spoofing turns SOCKS chains into transparent proxies.
iptables-based transparency beats manual proxy config for stubborn Android apps.
Instead of wrestling with raw mitmproxy output, this tool gives a purpose-built UI that shows system prompts, tool definitions, token accounting, streaming responses and tool calls — all in real time. The one-liner shell setup, keyboard shortcuts, and token breakdown make debugging Claude Code conversations startlingly quicker, though it’s inherently a local MITM (trust the generated CA) and is narrow by design to Anthropic’s workflow.
Clean Go proxy library, but goproxy and mitmproxy already own this space.
