# Alopex > Alopex is an open-source (MIT), self-hosted net worth tracker for people with European bank accounts. It syncs balances and transactions read-only from 2000+ banks over PSD2 (via Enable Banking), prices stocks and crypto, and stores everything in the user's own Supabase project. There is no Alopex server: the publisher never sees user data. Key facts: - License: MIT. Author: Marco D'Onghia. - Bank sync: PSD2 account information (read-only) via Enable Banking, 2000+ European banks (e.g. Revolut, Wise, Fineco). Syncs every 6 hours. Consent lasts 180 days. No US/Canadian banks. - Investments: holdings entered by the user, priced via Yahoo Finance; crypto via CoinGecko and a read-only Coinbase key. - Currencies: EUR, USD or GBP, daily ECB rates. - Categorization: user rules first, optional Google Gemini for the rest. - Also: Splitwise shared costs, reports, income vs expenses, subscription detection, transfer and refund pairing, "worth it?" Web Push prompts, installable PWA, CSV import. - Hosting: runs on the user's own Supabase, GitHub Actions and Vercel (free tiers), or Docker. Setup about 30 minutes in the browser via GitHub Codespaces. - Not included: budgets, savings goals, forecasts, broker sync. - Not financial advice. ## Links - [Live demo (fake data, no sign-up)](https://app.alopex.finance/demo) - [Backend repo, start here: sync, Edge Functions, setup](https://github.com/marcodonghiaa/alopex) - [Dashboard repo](https://github.com/marcodonghiaa/alopex-web) - [Landing page](https://alopex.finance/)
