Or open the repo in Codespaces and run ./setup.sh
- 2000+ European banks over PSD2
- Read-only access
- No Alopex server
Where your data goes
Four hops. The last two run under your own accounts, and nothing in this line is ours.
Your bank
Balances and transactions
Released under PSD2 account-information access. Read-only by law.
Enable Banking
Licensed relay
Fetches from the bank and hands the data on. Keeps no copy for Alopex.
Your Supabase
Postgres, your account
Row Level Security on every table. The service-role key never reaches the browser.
Your Vercel
The dashboard
Deployed from your fork. Updates arrive as pull requests you merge.
- Optional: Google Gemini, only if you add a key, receives transaction descriptions for categorization.
- Sync logs hold counts, never names or amounts. Alopex cannot move money.
Everything in one daily total
Bank sync over PSD2
Revolut, Wise, Fineco and 2000+ other European banks, synced every 6 hours.
Your category rules run first; Gemini fills the rest if you add a key.
Portfolio and crypto, auto-priced
Add holdings by ticker or ISIN; prices from Yahoo Finance and CoinGecko. Coinbase syncs with a read-only key.
Subscription detection
Billing frequency and true monthly cost of every recurring charge.
Transfers and refunds
Transfers between your accounts are not income; refunds pair with the original charge.
Spending by category
Where the month went, in categories you can rename and group.
"Worth it?" prompts
After a discretionary purchase, a push notification asks. The answer is saved on the transaction.
Shared costs
Split a transaction with someone; the owed share leaves your spending.
Installable PWA
On your phone's home screen, with a push reminder before bank consent expires.
Switching from Monarch, Finary or a spreadsheet
Monarch Money
Connects US and Canadian banks. Subscription. Your transactions live on their servers.
2000+ European banks over PSD2, free, in your own database.
Finary
European banks, hosted service, proprietary code.
Same scope, MIT licensed, self-hosted. It keeps working if we stop.
A spreadsheet
Typed by hand, no history, one currency.
Synced every 6 hours, daily history, EUR/USD/GBP. Import the spreadsheet as CSV.

Who it is not for
You bank outside Europe. PSD2 only. No Plaid, SimpleFIN or US banks.
You want someone else to run it. You host it, merge updates and renew bank consent every 180 days.
You want real-time balances. Sync runs every 6 hours; banks cap unattended access at about 4 calls a day.
You want budgets, goals or forecasts. Not today.
You want broker sync. You enter holdings; only Coinbase syncs balances.
Frequently asked questions
Is there an open-source alternative to Monarch Money or Finary?
Yes. Alopex is MIT-licensed and self-hosted: European bank accounts, stocks, ETFs and crypto in one dashboard, with the data in your own Supabase project.
How is Alopex different from Firefly III, Actual Budget or Ghostfolio?
Firefly III and Actual budget; Ghostfolio tracks investments. Alopex does net worth across bank accounts, investments and crypto, with EU bank sync built in.
Is Alopex free?
Yes, MIT. The default setup runs on free tiers of GitHub, Supabase, Vercel and Enable Banking, whose limits can change.
Which banks does Alopex support, and how long does access last?
Any of the 2000+ on Enable Banking, including Revolut, Wise and Fineco. Consent lasts 180 days; you get a reminder before it ends and renew without losing history.
Do I need a server to run Alopex?
No. Sync runs on GitHub Actions and the dashboard on Vercel. Docker is an option for a home server.
Can Alopex move money or make payments?
No. PSD2 account-information access and the Coinbase key are both read-only.
From the maker
I built Alopex because every net worth app I tried either could not see my Italian bank or wanted my transactions on its servers. This one runs on my own accounts, and the code is MIT so it keeps working if I stop.
