Portfolio analytics, answer-driven.
This is the official download page for Vector — a fast, local desktop app for Windows that tracks your portfolio and gives you clear, quantitative answers about its health. No accounts, no cloud, no subscriptions.
Vector doesn't just show you numbers. It tells you where your portfolio is heading, how much risk you're carrying, whether you're diversified, and what you should actually do about it — all from a modular, drag-and-drop dashboard powered by live market data.
Head to the Releases page to grab the latest .exe.
Requirements: Windows 10+ · x64 · ~45MB
This repository hosts the GitHub Pages site for Vector — the landing page you see at protonyx.dev. It is not the application source code.

Vector was developed with the assistance of Claude Code, Anthropic's AI coding tool. Most of my projects are not built this way — but part of being a good developer is staying curious and actually trying the tools that are changing the industry, not just reading about them. This project was an experiment in that spirit. The goal was to understand where AI-assisted development genuinely adds value, where it doesn't, and what that means for how I work going forward.
