The questions worth asking.
Straight answers, including the awkward one about the free alternatives.
Does it cover European listings?
Yes — Euronext Brussels and Amsterdam, Xetra, the LSE and more, alongside US markets, working out of the box with no setup.
If you'd rather run on your own licensed market data, you can add a free personal key from Twelve Data (US) or a paid one from EODHD (which covers European exchanges) in Settings. Entirely optional: the app is complete without one, and prices are configured for you by default.
How is this different from the free portfolio trackers?
Tools like Portfolio Performance are good, and they are genuinely free — but what they track is a portfolio. Manticore holds your whole financial position: income and recurring expenses, budgets, bank and savings, bonds, debts, a health score and a retirement plan, with the portfolio as one part of it.
If all you want is investment performance, use the free tool — it does that well. If you'd rather have every number in one place, and talking to the others, that's the gap this fills.
Do I need an API key to see prices?
No. Live stocks, ETFs and crypto work immediately, with nothing to configure and no account anywhere.
Adding your own data key is an upgrade, not a requirement — it moves you onto your own licensed feed. With an EODHD key it powers the charts, backtest, crash replay and the Fear & Greed index too, not just the live quotes.
Can I use it on more than one computer?
Yes. Point the app at a folder you already sync — a Dropbox, OneDrive or Google Drive folder, or a shared drive — and it keeps a second machine in step. That service moves the file; there's no server of ours involved.
Only the encrypted copy is written to that folder, so your holdings are never readable there, and it needs a passphrase set. If two machines are edited at once the newest change wins and the older one is kept as a backup — nothing is quietly lost.
Which platforms does it run on?
Windows 10 and 11. There is no macOS or Linux build yet, so if you're on a Mac this isn't for you today — better you know that before paying than after.
What if it isn't for me?
Email within 14 days of buying and you get a full refund, no questions asked and no form to fill in — the same window EU law gives you on any online purchase. You lose nothing by trying it: your data was only ever on your own machine anyway.
