Finly is an open-source, self-hosted personal wealth and budgeting system. It enables users to aggregate bank accounts, track net worth, organize budgets, and forecast cashflow locally without cloud reliance or subscription fees.

How does Finly connect to bank accounts?

Finly integrates the open-source Woob banking connector engine. Connections are established directly between your device's IP address and your financial institution using TLS encryption, completely bypassing third-party cloud data aggregators.

Is my financial data encrypted?

Yes. All banking credentials and sensitive session tokens are encrypted locally with AES-256 Fernet symmetric cryptography. Financial transactions and accounts are stored inside a local SQLite database on your own machine.

How is Finly an alternative to cloud apps like Finary or Bankin?

Unlike SaaS aggregators that store your financial history on multi-tenant cloud servers and charge monthly fees, Finly is 100% free (MIT license), runs locally on your machine, never monetizes data, and produces zero cloud telemetry.

Which platforms can run Finly?

Finly is available as a standalone desktop application for Windows (.exe), macOS (.dmg and universal zip), and Linux (.deb and tarball), as well as via Docker Compose for self-hosting on a NAS or personal server.

Knowledge Base

Frequently Asked Questions

Everything you need to know about Finly, security, banking connectors, and self-hosting.

What is Finly and how does it differ from cloud aggregators?

Finly is an open-source, 100% self-hosted wealth tracking and budgeting engine. Unlike cloud SaaS products (such as Finary, Bankin, or Mint) that monetize data or require recurring subscriptions, Finly runs entirely on your local hardware. All database queries, credentials, and transaction analyses stay within your control.

How does direct bank synchronization work without cloud servers?

Finly uses Woob (Web Outside of Browsers), a proven open-source multi-bank protocol engine. The sync process queries banking endpoints directly from your own IP address over TLS, eliminating the need for intermediate SaaS bridge servers or third-party credential brokers.

How are my banking passwords and tokens secured?

All bank connector configurations and authentication tokens are encrypted locally with AES-256 Fernet symmetric cryptography using a unique local encryption secret. No telemetry or credentials ever leave your physical device.

Which operating systems and deployment modes are supported?

Finly is available as a standalone desktop application for Windows 10/11 (.exe installer and portable), macOS (.dmg universal for Apple Silicon and Intel), and Linux (.deb and tarball). It can also be deployed headlessly via Docker Compose on a Raspberry Pi, Synology NAS, Unraid, or private VPS.

Can I export and own my raw financial transaction data?

Yes. Finly provides client-side Excel spreadsheet and PDF report exports, along with raw, direct SQLite database access so you can query your historical data with Python, SQL, or BI tools at any time.
