Actual Budget vs Firefly III: Self-Hosted Finance Showdown

Managing your finances with a self-hosted tool means your transaction history, bank balances, and spending habits never leave your control. No company is mining your purchase data for advertising insights. No subscription fee that doubles after the first year. Just your money, your data, your rules.

The two heavyweights in this space are Actual Budget and Firefly III. Both are open-source, both run beautifully in Docker, and both have passionate communities. But they approach personal finance from fundamentally different angles, and choosing the wrong one for your workflow will leave you frustrated.

The Philosophy Split

This is the most important thing to understand before we compare features.

Actual Budget is an envelope budgeting tool. Every dollar you earn gets assigned a job. You decide in advance how much goes to groceries, rent, entertainment, and savings. When a category runs out, you either stop spending or move money from another envelope. It is a digital implementation of the system your grandparents used with literal paper envelopes of cash.

Firefly III is a financial tracking and reporting tool. It records what happened — income, expenses, transfers — and helps you analyze your spending patterns through reports, charts, and budgets. It can do envelope-style budgeting too, but its core strength is comprehensive transaction management and financial reporting.

Think of it this way: Actual Budget tells you what you should spend. Firefly III tells you what you did spend. Both approaches have merit, and your preference depends on whether you need proactive spending control or retroactive spending analysis.

Feature Comparison

Deploying Both with Docker

Let us set up both so you can try them side by side.

Actual Budget

Actual is remarkably simple to deploy:

# docker-compose.yml for Actual Budget
version: "3.8"

services:
  actual:
    image: actualbudget/actual-server:latest
    container_name: actual-budget
    restart: unless-stopped
    ports:
      - "5006:5006"
    volumes:
      - actual_data:/data

volumes:
  actual_data:

That is it. No database to configure, no environment variables to set. Actual uses SQLite internally and stores everything in a single data directory. Start it with:

docker compose up -d

Navigate to http://your-server:5006, create an account, and you are budgeting within two minutes.

Firefly III

Firefly III requires a bit more setup because it uses a proper relational database:

# docker-compose.yml for Firefly III
version: "3.8"

services:
  firefly:
    image: fireflyiii/core:latest
    container_name: firefly-iii
    restart: unless-stopped
    ports:
      - "8080:8080"
    environment:
      APP_KEY: your-32-char-app-key-here-change
      DB_HOST: firefly-db
      DB_PORT: 5432
      DB_CONNECTION: pgsql
      DB_DATABASE: firefly
      DB_USERNAME: firefly
      DB_PASSWORD: secret_db_password
      TRUSTED_PROXIES: "**"
      APP_URL: https://firefly.yourdomain.com
    volumes:
      - firefly_upload:/var/www/html/storage/upload
    depends_on:
      - firefly-db

  firefly-db:
    image: postgres:15-alpine
    container_name: firefly-db
    restart: unless-stopped
    environment:
      POSTGRES_USER: firefly
      POSTGRES_PASSWORD: secret_db_password
      POSTGRES_DB: firefly
    volumes:
      - firefly_db:/var/lib/postgresql/data

  # Optional: automated imports
  firefly-data-importer:
    image: fireflyiii/data-importer:latest
    container_name: firefly-importer
    restart: unless-stopped
    ports:

The Budgeting Experience

Actual Budget: Focused and Opinionated

Actual forces you into envelope budgeting, and that is its greatest strength. When you receive income, you assign every dollar to a category. The interface makes this tactile and satisfying — you can see unbudgeted money at the top and drag it into categories.

The budget view is the star of the show. It is a clean spreadsheet-like grid showing each category, what you budgeted, what you spent, and what remains. Color coding instantly shows which categories are on track (green), overspent (red), or have surplus (gray).

Where Actual really shines:

• Goal-based budgeting: Set savings targets with deadlines and Actual calculates monthly contributions
• Credit card handling: Tracks credit card float correctly, so your budget reflects real purchasing power
• Rollover: Unspent budget amounts roll to the next month, building category savings naturally
• Speed: The SQLite-backed interface is blazingly fast, even with years of data

Firefly III: Comprehensive and Flexible

Firefly III does not push you into any particular methodology. You can use it as a simple expense tracker, implement envelope budgeting through its budget system, or build a detailed net-worth tracker using its account types (assets, expenses, revenue, liabilities).

Where Firefly III excels:

• Rules engine: Automatically categorize, tag, and modify transactions based on configurable rules. "If description contains 'STARBUCKS', set category to 'Coffee' and tag 'discretionary'" — and it applies retroactively
• Multi-currency: Full support for multiple currencies with exchange rate tracking. Essential if you earn in one currency and spend in another
• Reporting: Detailed charts for spending by category, income vs expenses over time, budget performance, net worth trends, and account balances
• Piggy banks: Virtual savings jars that help you save toward specific goals
• Bill tracking: Track recurring bills and see upcoming payments
• Audit trail: Every transaction records who changed what and when

Bank Sync Options

Both tools support automatic bank synchronization, but the landscape keeps shifting.

Actual Budget supports:

• GoCardless (formerly Nordigen): Free tier covers many European banks
• SimpleFIN: Covers US and Canadian banks for $1.50/month

Firefly III supports:

• GoCardless: Through the data importer
• Spectre (Salt Edge): Broader bank coverage but with API limits
• CSV import: Works with any bank that offers CSV exports

In practice, bank sync reliability varies wildly depending on your specific bank. Many self-hosters in both communities end up doing manual CSV imports because their bank's API integration is flaky. Do not choose your finance tool based on bank sync alone — it might not work with your bank regardless.

Data Model Differences

This matters more than you might think.

Actual Budget's data model is simple: accounts, categories, and transactions. Every transaction lives in one account and one category. This simplicity makes it fast and easy to understand, but limits what you can track.

Firefly III's data model is rich: asset accounts, expense accounts, revenue accounts, liability accounts, categories, tags, budgets, piggy banks, and more. Transactions connect source and destination accounts. A grocery purchase moves money from your "Checking Account" (asset) to "Grocery Store" (expense account). This double-entry-inspired system enables powerful reporting but takes longer to set up properly.

Actual Budget:
  Checking → [Groceries Category] → -$85.50

Firefly III:
  Checking Account (asset) → Grocery Store (expense)
    Category: Food
    Tags: weekly-shop, organic
    Budget: Groceries ($400/month)

Performance and Resources

Actual Budget wins here decisively. Its embedded SQLite database means no external dependencies, minimal resource usage, and instant startup. Firefly III's Laravel stack and external database add overhead, though it is still modest by modern standards.

Who Should Choose What

Choose Actual Budget if:

• You want proactive spending control (tell money where to go before spending)
• You prefer a focused, fast, minimal interface
• You are a single user or household managing one set of finances
• You primarily use one currency
• You want the simplest possible deployment and maintenance
• You follow or want to follow the YNAB methodology

Choose Firefly III if:

• You want comprehensive financial tracking and analysis
• You deal with multiple currencies regularly
• You need powerful automation rules for transaction categorization
• You want detailed reporting on spending trends over time
• You track debts, liabilities, or complex account structures
• You need multi-user support
• You want a full API for custom integrations

Migration Between Them

If you start with one and want to switch, both support CSV export and import. The process is not seamless — you will need to map categories and accounts manually — but it is doable. I would recommend running both in parallel for a month before committing to a switch.

My Recommendation

For most self-hosters managing a household budget, start with Actual Budget. Its opinionated approach to envelope budgeting is genuinely effective at changing spending behavior, and the deployment is trivially simple. You will be budgeting in under five minutes.

If you outgrow it — you need multi-currency support, detailed reports, or complex transaction rules — migrate to Firefly III. It is the more powerful tool, but that power comes with more setup time and a steeper learning curve.

The best finance tool is the one you actually use. Both are excellent, both are actively maintained, and both keep your financial data exactly where it belongs: on your own server.
