Deploy and Host Firefly III on Railway

Deploy Firefly III on Railway to run your own private, open-source personal finance manager with full double-entry bookkeeping, budgets, categories, and multi-currency support. Self-host Firefly III with complete data ownership — no ads, no tracking, no third-party access to your financial data.

This Railway template pre-configures Firefly III (fireflyiii/core:latest) with a PostgreSQL database, persistent upload storage, and production-ready environment variables including secure encryption keys and trusted proxy settings behind Railway's TLS-terminating edge.

Getting Started with Firefly III on Railway

After deployment completes, visit your Railway-generated public URL. Firefly III automatically runs database migrations on first boot and generates encryption keys. You'll land on the registration page where you can create your first user account — this becomes the administrator. Once registered, navigate to the dashboard and create your first asset account (checking, savings, credit card). Add your first transaction to start tracking finances. Set up budgets under the Budgets menu to allocate monthly spending limits across categories.

About Hosting Firefly III

Firefly III is a free, open-source (AGPLv3) personal finance manager created by James Cole. It uses double-entry bookkeeping — every transaction has both a source and a destination — giving you an accurate picture of where money flows. Unlike cloud-based tools like YNAB or Mint, Firefly III runs entirely on your own infrastructure and never contacts external servers unless you explicitly configure it to.

Key features of self-hosted Firefly III include:

• Double-entry bookkeeping with support for withdrawals, deposits, and transfers
• Multi-currency support — track accounts and transactions in any currency
• Budgets, categories, and tags for organizing spending
• Advanced rule engine that auto-categorizes transactions based on conditions
• Data Importer for CSV, OFX, and bank-connected imports via Spectre/Nordigen
• JSON REST API with full CRUD access and optional webhooks
• Recurring transactions for automated entries on schedules
• Reports and charts showing spending per week, month, year, or custom range

Why Deploy Firefly III on Railway

• One-click deploy with PostgreSQL and persistent storage pre-configured
• No server management — Railway handles scaling, SSL, and uptime
• Persistent volume keeps uploaded attachments safe across redeploys

Common Use Cases for Self-Hosted Firefly III

• Personal budgeting — track income and expenses across multiple bank accounts with envelope-style budgets
• Multi-currency expense tracking — manage finances in different currencies for travel, remote work, or international accounts
• Automated transaction categorization — use the rule engine to auto-tag and sort recurring transactions from bank imports
• Financial reporting for freelancers — generate income/expense reports by category with double-entry accuracy for tax preparation
