How to Install Monline on Your Synology NAS

Monline is a self-hosted application for tracking subscriptions, recurring payments, and budgets. It pairs a React frontend with a Node.js server and embedded SQLite storage, offering subscription management with automatic logos and flexible billing, a payment calendar, budget overviews, payment insights, bank statement imports from services like Enpara, DenizBank, and Garanti BBVA, multi-language support, themes, and secure private accounts with optional two-factor authentication and reminders. After months of juggling spreadsheet tabs and forgotten renewal dates, I finally set up Monline on my Synology NAS and it quickly became the single place I check every morning for upcoming charges. The clean calendar view and automatic logos made my subscriptions feel manageable instead of scattered, and the bank statement import from Enpara saved me from manually entering months of history. In this step by step guide I will show you how to install Monline on your Synology NAS using Docker & Dockhand.

💡Note: This guide works perfectly with the latest Monline v1.3.0 release.

Install Dockhand using my step by step guide. If you already have Dockhand installed on your Synology NAS, skip this STEP. ⚠️Attention: Make sure you have installed the latest Dockhand version.

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it monline. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Open your browser and type in http://synology-ip-address:3866 to connect to your Dockhand container. On the left sidebar, click Stacks then + Create. Follow the instructions in the image below.

• STEP 5

In the Stack name field, type in monline. ⚠️Warning: Type in the name in lowercase letters. The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Follow the instructions in the image below.

Note: Copy Paste the code below in the Dockhand Compose Stack then click Create & Start.

I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
