Hi Product Hunt 👋
I'm not a professional developer. I got tired of maintaining a
spreadsheet to track my investments across multiple currencies — broken
formulas after every update, manual exchange rate updates, no real
history of how the portfolio evolved over time.
So I built Aures Portfolio: a free tool to track a multi-currency
investment portfolio, with a few things I cared about for myself:
- No account — open the page and start
- No server storing your data — everything stays in your browser
- No ads, no tracking beyond basic anonymous page-view stats
- Multi-currency support with automatic conversion to your base currency
- Transactions with realized gains/losses calculated automatically
- Dividends/coupons tracked toward total return
- Historical snapshots + annualized return (XIRR)
- Optional rebalancing view
- Multiple portfolios (e.g. yours and a family member's)
- PDF report export
It's a single HTML file — you can literally download it and use it
offline.
I built this to solve my own problem first, so I know it's not perfect.
I'd love your feedback, bug reports, or ideas for what's missing — I'm
actively working on it and will do my best to act on suggestions.

finally a portfolio tracker that doesnt ask me to sign up or sell my data, the single file setup is wild and it loaded my csv in seconds

@ercansusamrokb Thanks, that means a lot! The single-file thing started as a personal
constraint (I wanted something I could just download and keep
forever, no infrastructure to babysit) and it turned out to double as
the whole "no data leaves your machine" pitch,
Glad the CSV import worked smoothly — let me know if you run into
anything as you use it more, always looking for edge cases to fix.

Love that it lives in a single file with zero accounts. The fact that nothing leaves the browser is honestly such a relief compared to every other portfolio tracker begging for signups and selling data.

@gozenmasal15969 Thank you so much! Privacy and simplicity have been the cornerstones of the project from the beginning. I wanted a tool that gave users full control over their financial data, without tracking or forced registration. I'm really happy you appreciate its design.

Love that it just lives in a single file with no signup nonsense. The multi-currency view finally beats the janky spreadsheet I had been wrestling with.
