Free Portfolio Tracker

A privacy-first, open source investment portfolio tracker that runs entirely in your browser — no account, no backend, no cost.

✅ 100% Free 🔒 Privacy First 📂 Open Source

💡 Why this exists

Most portfolio trackers either cost money, require you to hand over your brokerage credentials, or lock your data on their servers. We wanted something different — a tool that's genuinely free, keeps your data on your own device, and doesn't need a login to work.

Free Portfolio Tracker was built for people who want a clear picture of their investments across different asset classes — stocks, crypto, metals, and savings — without giving up their privacy or paying a monthly fee.

🧭 Core Principles

🔒

Your data stays with you

All portfolio data is stored in your browser's localStorage. Nothing is sent to any server we run. You are the only one who can see your holdings.

🆓

Free forever

No premium tiers, no paywalled features, no "free trial." Everything in the app is available to everyone, always.

⚡

No account required

Open the app and start adding assets immediately. No email, no password, no sign-up flow.

📂

Open source

The full source code is publicly available on GitHub. You can inspect every line, self-host it, or contribute improvements.

🛠️ Technology Stack

Built with plain, dependency-free web technologies. No frameworks, no build steps, no node_modules — just files you can open in a browser.

Vanilla HTML/CSS/JS

Zero frontend frameworks. Fast, lightweight, works everywhere.

localStorage

All data persisted locally in the browser. No backend needed.

Chart.js

Powers the portfolio charts and history visualisations.

Finnhub API

Real-time stock and crypto price data (free tier).

Metals.dev API
