By hosting Firefly III on a Raspberry Pi, users can benefit from an always-on private finance system that integrates with banks and other services through the API.


Before installing Firefly III, ensure the Raspberry Pi is configured with:

  • Raspberry Pi OS installed as the operating system
  • Access to command line through terminal/SSH
  • Git for cloning code repositories
  • PHP 7.4+ to run Firefly III
  • MySQL or MariaDB database server
  • Web server like Apache or Nginx

Optional but recommended programs are Composer for PHP dependency management and SSL encryption for secure remote access.

Step-by-Step Installation Guide

With the prerequisites ready, here is a step-by-step guide to deploy Firefly III:

  1. Clone the Firefly III repository:


git clone

Install PHP dependencies:

composer install

Copy and configure the environment file:

cp .env.example .env

Generate application key:

php artisan key:generate

Create a new MySQL/MariaDB database for Firefly III

Update .env file with database connection details

  1. * * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1

  2. Create user account through registering on web interface

At this point, the Firefly III installation is ready to use! Continue reading for optimization tips.

Optimization for Raspberry Pi Infrastructure

Here are some areas to optimize Firefly III for a Raspberry Pi deployment:

Memory Usage

As an PHP application, optimize the amount of memory allocated to PHP:


sudo nano /etc/php/7.4/fpm/php.ini

Tweak the memory limit to 128-256 MB depending on hardware capacity.


For the database, use MariaDB instead of MySQL for lower memory usage. Also ensure durable write caching is enabled for faster transacations.


Enable Redis or Memcached object caching for frequently accessed data like transactions and currency conversion rates. Use Redis for more performance gains.

Web Server

Use a lightweight web server like Nginx/php-fpm instead of Apache. Also enable HTTP compression and caching for faster page loads. Consider restricting access to the Firefly III IP for security.

Scheduled Jobs

Set up cron jobs or system timers for running scheduled tasks like bank data imports and currency rate updates. Optimize job frequency based on importance vs hardware capacity.

With these optimizations, Firefly III can work well for home finance tracking from a Raspberry Pi. Continue reading for enhancing the user experience further.

Enhancing the User Experience

In addition to the technical setup, consider these tips for making Firefly III more user-friendly:


Upload a user profile picture, set budget thresholds, customize category rules and buttons – personalize Firefly to match individual preferences and money management style.

Rules and Webhooks

Automate mundane finance tasks by configuring transaction auto-categorization rules based on payees, amounts or notes. Set up webhooks like bank account triggers for automatic transaction creation.


Set monthly, yearly or custom budgets for better spending control. Use bill reminders and limits for anticipating expenses. Leverage bulk edit for quick budget adjustment based on life changes like having a child, buying a house or retiring.

Mobile Access

Enable HTTPS encryption and use the Progressive Web App features for mobile access to Firefly III like a native application. Alternatively, use the unofficial Android app.

Financial Insights

Review net worth and account balance dashboards frequently. Generate spending reports by year, month, category or budget to uncover trends and outliers. Click through charts for transaction details.

Automatic Backups

Set up daily automated MySQL backups stored securely outside the webroot to mitigate data loss risk from SD card corruption or hardware failure.

Optimizing technical performance and enhancing the user interface allows harnessing the full power of Firefly III for at-home financial management on a Raspberry Pi.
