How to Install Mitra on Your Synology NAS

Mitra is a self-hosted calendar that puts events and tasks on a single timeline so you can see when there is actually room to get things done. It runs as a single Docker container with its own database, stores calendars locally if you prefer, and syncs bidirectionally with CalDAV, Google Calendar, Apple Calendar, Notion, Todoist, and Tempo. Multiple views (week, month, year, timeline, and table) support drag-and-drop creation, moving, and resizing of entries, while a Planning tab holds undated tasks with due dates and estimates that you can drag into free slots. Further capabilities include availability shading, subtasks and dependencies, file attachments, push notifications, guest lists, a command palette, AI connectors over the Model Context Protocol for tools such as Claude and Cursor, multi-language support (including right-to-left), light/dark themes, and optional multi-user sign-in via OpenID Connect. No telemetry. I’ve been running Mitra on my home server for the past few months and it is the only planning tool I actually stick with. Because events and tasks share one timeline I finally stopped switching between a calendar and a separate to-do list, and dragging tasks from the Planning tab straight into free time in the week view makes scheduling feel natural rather than forced. I use it mainly for the privacy and flexibility it gives me: everything stays on my NAS. In this step by step guide I will show you how to install Mitra on your Synology NAS using Docker & Dockhand.

💡Note: This guide works perfectly with the latest Mitra v0.7.1 release.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

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.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it mitra. 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 mitra. ⚠️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.

services:
  mitra:
    image: ghcr.io/a11delavar/mitra:latest
    container_name: Mitra
    healthcheck:
      test: timeout 10s bash -c ':> /dev/tcp/127.0.0.1/3000' || exit 1
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 90s
    ports:
      - 8103:3000
    volumes:
      - /volume1/docker/mitra:/app/data:rw
    environment:
     MITRA_URL: http://192.168.1.18:8103 #or your own reverse proxy or domain name with https:// at the beginning.
    restart: on-failure:5

Note: Before you paste the code above in the Stack editor area below, change the value for MITRA_URL with your own Local NAS IP with http:// at the beginning and :8103 at the end.

• STEP 6

If everything goes right, you will see the following message at the bottom right of your screen: “Created stack “mitra”“.

• STEP 7

On the left sidebar, click Containers. Identify your Mitra container then click on ports 8103:3000. Follow the instructions in the image below.

• STEP 8

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. 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.

• STEP 9

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://synology-ip-address:8103 Click Add your first integration. Follow the instructions in the image below.

• STEP 10

Select the integration that you want. I chose Mitra, no account needed. Follow the instructions in the image below.

Choose a name for the Calendar. Click Save. Follow the instructions in the image below.
