Actual Budget vs Firefly III: Choosing the Right Self-Hosted Finance Tool

Both Actual Budget and Firefly III are excellent self-hosted personal finance tools, but they solve fundamentally different problems. Picking the wrong one means either fighting against a tool that does not match how you think about money, or migrating your data six months in. This guide breaks down the real differences so you can choose correctly the first time.

The Core Philosophy Difference

This is the most important distinction and the one most comparison articles gloss over.

Actual Budget is a budgeting tool. It answers the question: "How should I spend the money I have right now?" Every dollar gets assigned to a category before you spend it. It is forward-looking and prescriptive.

Firefly III is a personal accounting system. It answers the question: "Where did my money go, and what is my financial position?" It tracks transactions across accounts, categorizes spending, and generates reports. It is backward-looking and descriptive.

Both can do budgeting. Both can track transactions. But their design centers on opposite sides of the personal finance equation, and that shapes everything from the UI to the data model.

Architecture Comparison

What Local-First Actually Means

Actual Budget stores your budget in the browser using IndexedDB. When you open the app, you are working with a local copy. The sync server is just a relay -- it stores encrypted blobs and coordinates changes between your devices. If the server goes down, you keep working.

Firefly III is a traditional server application. The web UI makes API calls to the server, which reads and writes a database. If the server goes down, you have no access to your data until it comes back.

This matters most for reliability and speed. Actual Budget feels instant because every interaction is local. Firefly III has noticeable latency on every action because it round-trips to the server.

Docker Compose: Side by Side

Actual Budget

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

volumes:
  actual_data:

That is the entire stack. No database, no cache, no workers. The server is lightweight because it only handles sync and file storage.

Firefly III

services:
  firefly:
    image: fireflyiii/core:latest
    ports:
      - "8080:8080"
    environment:
      APP_KEY: "your-32-char-random-key"
      DB_CONNECTION: pgsql
      DB_HOST: firefly-db
      DB_PORT: "5432"
      DB_DATABASE: firefly
      DB_USERNAME: firefly
      DB_PASSWORD: "${FIREFLY_DB_PASSWORD}"
    volumes:
      - firefly_upload:/var/www/html/storage/upload
    depends_on:
      - firefly-db
    restart: unless-stopped

  firefly-db:
    image: postgres:16-alpine
    environment:
      POSTGRES_DB: firefly
      POSTGRES_USER: firefly
      POSTGRES_PASSWORD: "${FIREFLY_DB_PASSWORD}"
    volumes:
      - firefly_db_data:/var/lib/postgresql/data
    restart: unless-stopped

  firefly-importer:
    image: fireflyiii/data-importer:latest
    ports:
      - "8081:8080"
    environment:
      FIREFLY_III_URL: http://firefly:8080
      FIREFLY_III_ACCESS_TOKEN: "${FIREFLY_API_TOKEN}"
    depends_on:
      - firefly
    restart: unless-stopped

volumes:
  firefly_upload:
  firefly_db_data:

Three containers, a real database, environment variables to configure, and a separate data importer service. More to maintain, but also more infrastructure to work with if you want to build integrations.

Budgeting Workflows

Actual Budget: Envelope Method

1. Income arrives in your checking account
2. You open Actual and assign every dollar to a budget category
3. As you spend, transactions reduce the category balance
4. When a category hits zero, you either stop spending or move money from another category
5. At month end, unused balances roll forward automatically

The workflow is simple and opinionated. You cannot overspend a category without explicitly choosing to. This constraint is the entire point -- it forces conscious spending decisions.

Firefly III: Track and Analyze

1. Transactions flow in via manual entry, CSV import, or bank sync
2. The rule engine auto-categorizes them based on patterns you define
3. You optionally set monthly budgets per category
4. Reports show spending trends, income vs expenses, and net worth over time
5. Piggy banks track savings goals with visual progress

Firefly III is more flexible but less prescriptive. You can set budgets, but the system does not force you to allocate every dollar. You can run it purely as a transaction tracker without budgeting at all.

Bank Sync and Data Import

Firefly III wins on auto-categorization. Its rule engine can match transactions by amount, description, source account, or any combination, and automatically apply categories, tags, and notes. Actual Budget has basic matching but nothing as sophisticated.

Actual Budget wins on import simplicity. Drag a CSV or OFX file into the app and map the columns. With Firefly III, you configure the separate data importer service, which adds complexity.

Reporting and Analytics

Firefly III is significantly stronger here. It provides:

• Net worth over time with multi-currency support
• Income vs expense breakdowns by period
• Category spending trends across months
• Budget performance with rollover tracking
• Tag-based reports for custom analysis
• Asset accounts with balance tracking

Actual Budget has basic reporting -- spending by category, trends over time, and net worth. It is sufficient for someone focused on budgeting, but if you want to understand your complete financial picture, Firefly III is the better analytical tool.

Multi-Currency Support

Firefly III handles multiple currencies natively. You can have accounts in different currencies, and it tracks exchange rates for accurate net worth calculations.

Actual Budget has basic multi-currency support, but it is less mature. If you regularly deal with money in multiple currencies, Firefly III handles this more gracefully.

Which One Should You Choose?

Choose Actual Budget if:

• You want to control your spending proactively (envelope budgeting)
• You value simplicity and speed over features
• You want offline access and local-first data
• You are a single user or household sharing one budget
• You are coming from YNAB and want a familiar workflow
• You want minimal server maintenance

Choose Firefly III if:

• You want to track and analyze where your money goes
• You need strong auto-categorization rules
• You have accounts in multiple currencies
• You want detailed financial reports and net worth tracking
• You need piggy banks and savings goals
• You want a full REST API for custom integrations
• You think of personal finance as accounting, not budgeting

Consider Running Both

This is not a joke. Some people run Actual Budget for active budgeting (deciding how to spend) and Firefly III for historical tracking and reporting (understanding where money went). The two tools complement each other because they solve different problems. If you have the server resources and do not mind maintaining both, it is a legitimate setup.

The Bottom Line

Neither tool is objectively better. They are different tools for different approaches to personal finance. Actual Budget is the better budgeting tool. Firefly III is the better financial management platform. The right choice depends on whether you need to control your spending or understand it. If you are not sure, start with Actual Budget -- it is simpler to deploy, easier to learn, and you can always add Firefly III later for analytics without losing anything.
