Syllogic

What is Syllogic

Syllogic is an open-source, self-hosted personal finance dashboard that gives you control over your financial data. It offers AI-powered categorization, recurring spend tracking, and a live demo. You can run it on your own infrastructure using Docker, Railway, or CasaOS, keeping your balances, transactions, and imports on servers you control.

How to use Syllogic

1. Try the live demo – Visit the Syllogic app and log in with a demo account to explore the UI and workflows before deploying.
2. Self-host with Docker – Use Docker Compose to run the full stack (frontend, backend, PostgreSQL, Redis) on your own VPS, homelab, or NAS. A one-line install script is available.
3. Deploy on Railway – Use the one-click Railway template for a fast hosted setup with managed PostgreSQL, Redis, custom domain, and SSL.
4. Import transactions – Upload bank CSVs to populate your accounts. Optional AI categorization via OpenAI can enrich transactions.
5. Track finances – View balances, cash flow, spending categories, recurring subscriptions, and link transfers across accounts.
6. Export data – Download your data as CSV at any time with no lock-in.
