Firefly III is a self-hosted manager for your personal finances. It can help you keep track of your expenses and income so you can spend less and save more. Firefly III supports the use of budgets, categories and tags. Using a bunch of external tools, you can import data. It also has many neat financial reports available. Firefly III should give you insight into and control over your finances. In this step by step guide I will show you how to install Firefly III on your Synology NAS using Docker & Portainer. With the updated Firefly guide below you will be able to set up recurring transactions.

💡Note: This guide works perfectly with the latest Firefly III 6.1.24 release.
