"Firefly III" is a financial manager. It can help you keep track of expenses, income, budgets and everything in between. It even supports credit cards, shared household accounts and savings accounts! It's pretty fancy. You should use it to save and organise money.

Personal financial management is pretty difficult, and everybody has their own approach to it. Some people make budgets, other people limit their cashflow by throwing away their credit cards, others try to increase their current cashflow. There are tons of ways to save and earn money.

Firefly works on the principle that if you know where you're money is going, you can stop it from going there.

To get to know Firefly, and to see if it fits you, check out these resources:

• The screenshots below on this very page.
• The featurelist below, also on this very page.
• The full description, which will tell you how Firefly works, and the philosophy behind it.

Firefly is a system you'll have install yourself on webhosting of your choosing. It needs PHP and MySQL. The current version of Firefly III requires PHP 5.6.4 or higher. Soon, this will be PHP 7.0.0 or higher.

It's III, or 3, because version 2 and version 1 (not online) preceded it. It has been growing steadily ever since.

• A double-entry bookkeeping system;
• You can store, edit and remove withdrawals, deposits and transfers. This allows you full financial management;
• You can manage different types of accounts;
  • Asset accounts
  • Shared asset accounts (household accounts)
  • Saving accounts
  • Credit cards
• It's possible to create, change and manage money using budgets;
• Organize transactions using categories;
• Save towards a goal using piggy banks;
• Predict and anticipate bills;
• View income / expense reports;
• Organize expenses using tags;
• Lots of help text in case you don't get it.

Everything is organised:

• Clear views that should show you how you're doing;
• Easy navigation through your records;
• Browse back and forth to see previous months or even years;
• Lots of charts because we all love them;
• Financial reporting showing you how well you are doing.

Please note that everything in these screenshots is fictional and may not be realistic.

If you're still interested please read the installation guide, the upgrade guide (if applicable) and the first use guide.

If you want to try out Firefly III, you can do so on this dedicated website. This site always runs the latest version of Firefly III. If you want to use it, please read the privacy considerations for this demo-site. Accounts on the demo sites will stop working after one month. It's a trial.

You should always run Firefly III on a site with TLS enabled (https://). Please note that although some parts of the database are encrypted (transaction descriptions, names, etc.) some parts are not (amounts, dates, etc). If you need more security, you must enable transparent database encryption or a comparable technology. Please remember that this is open source software under active development, and it is in no way guaranteed to be safe or secure.

Firefly III is currently available in Dutch and English. Support for other languages is being worked on. I could use your help. Checkout Crowdin for more information.

Firefly III uses the following libraries and tools:

• The AdminLTE template by Almsaseed Studio

• For development, some of the excellent tools made by Barry van den Heuvel
• Bootstrap sortable by Matúš Brliť.
• Date range picker by Dan Grossman

Firefly III is pretty much all grown up. Full test coverage (nerd alert!) is coming. Translations are a work in progress.
