SnapOtter

SnapOtter is a fully self-hosted image manipulation platform that runs 100% locally in a single Docker container. It combines 47 image processing tools, powerful local AI models for background removal, upscaling, photo restoration, and more, plus flexible pipelines for building reusable batch workflows. Everything stays completely private on your hardware with zero cloud dependency, so your images never leave your NAS. It features a clean web UI for quick edits and a full REST API for automation and integration. In this step by step guide I will show you how to install Snapotter

Step 1

Install container manager, If you have already installed the manager jump to step 3

Select Main menu or the Package Center shortcut

Step 2

Type in Container in the Search bar and Press enter on your keyboard. Then you will See Container manager like below. in my case i have installed the Container manager already. Select install, wait a few second and then select open.

Step 3

Now you have selected open you should see a screen like below and The Manager will say Running in green. Select open and move on to the next step.

Step 4

Now you will be Presented with the below. This is the Container manager over view of all your Containers and what’s happening in real time.

Step 5

Select project from the menu down the side and then select Create button

Step 6

before we go any thurther we need to ensure we have our folders setup ready for the project.

I have a main folder on the Synology system just for docker projects. create the following folders using filestation so my path for Termix will look like this

snapotter

snapotter/data

Step 7

now we have created the folders needed for the project we can go ahead and create the project in Container manager

Give the project a name, change source to Create docker-compose.yml and add the path. Project name is all lower case.

See below for before and after the code you will need is below also.

the volume path needs tobe exact or the project will return a fail. like above i missed out projects folder so i got a error and had to trouble shoot.

services:
  snapotter:
    image: snapotter/snapotter:latest
    container_name: SnapOtter
    ports: 
      - 1349:1349
    volumes:
      - /volume1/docker/projects/snapotter/data:/data:rw
    environment:
      AUTH_ENABLED: true
      DEFAULT_USERNAME: user
      DEFAULT_PASSWORD: password
      PUID: 1024
      PGID: 100
      STORAGE_MODE: local
    restart: on-failure:5

press next when you are happy with the code

Step 8

setup a web portal if you like . I would not advise it. and press next

Step 9

Step 10

If you have a Exit Code of 0 like i have below then you are done. project created. if you have a Exit code 1 you have a error and need to visit the code again and trouble shoot.

Step 11

One last thing you can check to see if the docker is Green and showing no Errors, todo that just goto Container manager and on the left select Projects. There’s a Status Colum there the project should be green if not you will need to trouble shoot.

Note : Don’t forget to edit the path of the container.

Step 12

Now lets create a tunnel for the container so we can use this outside the network. I use Cloudflare for my hosting portal.

Step 13

Try the tunnel to see if the container is working outside our network.

We have access outside our home network.

Step 14

Now Login and change your password.

Step 15

your in and ready to start using SnapOtter.

Happy Picture editing..
