What I ship

TrafficKit

See every request your apps make. Decrypt HTTPS in one click. Let your AI read it too.

A free HTTP/HTTPS debugging proxy with a fast desktop UI.

One-click intercepted browsers and terminals, HTTPS included
Live inspector for headers, bodies, timings and WebSocket frames
Virtualized table that stays smooth at tens of thousands of requests
Built-in Model Context Protocol server so Claude, Cursor and VS Code can read your traffic, with secrets redacted first
Everything stays in memory on your machine

QRForge

Design in the browser. Self-host dynamic codes. Measure scans without tracking people.

An open-source QR code platform covering the whole lifecycle.

Browser designer with shapes, logos, frames and a scan-quality check
Static codes render fully client-side, nothing is uploaded
Dynamic codes from your own server: editable, expiring, password-protected
Anonymous analytics: devices, countries, referrers, no third-party trackers
Ships as @qrforge/core, @qrforge/react, a CLI and a REST SDK

Try the live Studio →

WireKit

Parse, inspect and rewrite what crosses the wire. Every parser fuzzed.

The protocol layer under TrafficKit, as a Go library.

HTTP messages with headers in wire order and RFC 6265 cookie checks
WebSocket frames, reassembly and close codes
TLS certificates and a ClientHello parser with SNI and JA3
gzip, brotli and zstd decoding with bomb limits
Nothing panics on hostile input, every size is bounded

How I build

🖥️ Local-first

Software should work on a plane, in a basement, and after the company behind it disappears. Data stays where it was created.

🔓 Free, actually

MIT licensed. No paid tier, no usage caps, no "contact sales". If a feature exists, you have it.

🤖 AI-native, not AI-hostage

Tools expose their state over MCP so your assistant can help. Secrets are redacted before anything leaves the process.

Stack

_{Go for engines that must be fast and boring. React for interfaces. Rust + Tauri when it has to live on the desktop.}

Activity

Talk to me

Found a bug, want a feature, or built something on top of one of these? Open an issue or a discussion. I read all of them.

_{⭐ A star on any of these repos is the cheapest way to tell me to keep going.}
