Setup

Prerequisites

• Docker & Docker Compose (for containerized installation)
• Python 3.11+ (for local installation only)
• API keys for the stores you want to sync (see Configuration)

Option 1: Pre-built Image (Recommended)

The easiest way to run Backlogia—no cloning or building required.

1. Create a directory for Backlogia

   mkdir backlogia && cd backlogia

2. Download the configuration files

   curl -O https://raw.githubusercontent.com/sam1am/backlogia/main/.env.example
   curl -O https://raw.githubusercontent.com/sam1am/backlogia/main/docker-compose.ghcr.yml

3. Create your environment file

   cp .env.example .env

4. Edit .env with your settings (see Configuration)

5. Start the container

   docker compose -f docker-compose.ghcr.yml up -d

6. Access Backlogia at http://localhost:5050

Updating (Pre-built Image)

docker compose -f docker-compose.ghcr.yml pull
docker compose -f docker-compose.ghcr.yml up -d

---

Option 2: Build from Source (Docker)

Build the image locally from the repository.

1. Clone the repository

   git clone https://github.com/sam1am/backlogia.git
   cd backlogia

2. Create your environment file

   cp .env.example .env

3. Edit .env with your settings (see Configuration)

4. Start the container

   docker compose up -d

5. Access Backlogia at http://localhost:5050

Updating (Build from Source)

git pull
docker compose down
docker compose up -d --build

---

Docker Volumes

Volume	Purpose
./data:/data	Database and persistent storage
./data/legendary:/root/.config/legendary	Epic Games authentication cache
./data/nile:/root/.config/nile	Amazon Games authentication cache
${GOG_DB_DIR}:/gog:ro	GOG Galaxy database (read-only)
${LOCAL_GAMES_DIR_N}:/local-games-N:ro	Local games folders 1-5 (read-only, add more in docker-compose.yml if needed)

---

HTTPS Access (Optional)

Enable HTTPS access via a Caddy reverse proxy. This is useful for:

• Using the bookmarklet from HTTPS sites (avoids mixed-content blocking)
• Accessing Backlogia from other devices on your network

Enable HTTPS:

Add to your .env file:

COMPOSE_PROFILES=https

Then restart:

docker compose down && docker compose up -d --build

Access URLs:

URL	Scope
https://backlogia.localhost	Local machine only
https://backlogia.local	Any device on your network (requires mDNS)

Network Access (backlogia.local):

On macOS, Docker runs in a VM and can't broadcast mDNS directly. Run this helper script in a separate terminal:

./scripts/advertise-mdns.sh

On Linux hosts, mDNS is advertised automatically via Avahi.

Trusting the Certificate:

Caddy generates a self-signed certificate. Your browser will show a warning on first visit. You can click past it. To trust it permanently on macOS:

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ./data/caddy_data/pki/authorities/local/root.crt

---

Option 3: Local Installation

1. Clone the repository

   git clone https://github.com/sam1am/backlogia.git
   cd backlogia

2. Create a virtual environment

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies

   pip install -r requirements.txt

4. Create your environment file

   cp .env.example .env

5. Edit .env with your settings (see Configuration)

6. Initialize the database

   python scripts/build_database.py

7. Run the application

   python web/app.py

8. Access Backlogia at http://localhost:5050

Updating (Local Installation)

git pull
pip install -r requirements.txt

Then restart the application.

Configuration

Configure all store connections through the Settings page in Backlogia. Each store section includes step-by-step instructions for obtaining the required credentials.

Where to Get Credentials

Store	Credential Source
Steam	Steam Web API for API key
IGDB	Twitch Developer Console (IGDB uses Twitch auth)
Epic Games	OAuth flow in Settings page
GOG	Reads from local GOG Galaxy database OR uses bookmarklet import (instructions in Settings)
itch.io	itch.io API Keys
Humble Bundle	Session cookie from browser (instructions in Settings)
Battle.net	Session cookie from browser (instructions in Settings)
Amazon	OAuth flow in Settings page
EA	Bearer token via bookmarklet (instructions in Settings)
Xbox / Game Pass	XSTS token via bookmarklet or browser DevTools (instructions in Settings). Game Pass catalog syncs without authentication.
Ubisoft	Bookmarklet import from account.ubisoft.com (instructions in Settings)
Local Folder	Configure paths in .env file (see Local Games below)

Local Games

Import games from local folders on your machine. Each subfolder is treated as a game and matched to IGDB for metadata.

Setup:

1. Add your game folder paths to .env (up to 5 by default):

   LOCAL_GAMES_DIR_1=/path/to/games
   LOCAL_GAMES_DIR_2=/mnt/storage/more-games
   # Add more in docker-compose.yml if you need more than 5

2. Restart the container (paths are mounted automatically):

   docker compose down && docker compose up -d

3. Click "Sync Local" in Settings to import games

Folder Structure:

/path/to/games/
├── The Witcher 3/          → Imported as "The Witcher 3"
├── DOOM 2016/              → Imported as "DOOM 2016"
└── Hollow Knight/          → Imported as "Hollow Knight"

Override File (game.json):

For better IGDB matching or custom names, create a game.json file inside any game folder:

{
  "name": "The Witcher 3: Wild Hunt",
  "igdb_id": 1942
}

All fields are optional:

Field	Description
name	Override the game name (used for display and IGDB matching)
igdb_id	Manually specify the IGDB game ID for exact matching
description	Custom description
developers	Array of developer names, e.g. ["CD Projekt Red"]
genres	Array of genres, e.g. ["RPG", "Action"]
release_date	Release date in ISO format, e.g. "2015-05-19"
cover_image	URL to a custom cover image

Example game.json:

{
  "name": "DOOM (2016)",
  "igdb_id": 7351,
  "developers": ["id Software"],
  "genres": ["FPS", "Action"]
}

After syncing local games, run "Sync Missing Metadata" to fetch cover images, ratings, and other data from IGDB.
