Epic Games Store Weekly Free Games

Automatically login and find available free games the Epic Games Store. Sends you a prepopulated checkout link so you can complete the checkout after logging in. Supports multiple accounts, login sessions, and scheduled runs.

Setup

JSON Configuration

The tool can be configured with a combination of JSON and environment variables. The config file supports JSON5 syntax (comments, trailing commas, etc). For each property, the JSON config value takes priority over the respective environment variable value.

For details on each option, its defaults, and environment variable key, see the config documentation site.

The config file is stored in the mounted /usr/app/config volume and can be named config.json or config.json5.

Web server

This project can occasionally ask you to login via device code authentication. Epic Games's device code session expires after 10 minutes, so this project uses a web server and redirect to prevent from sending you a new link every 10 minutes. There are two options for running the web server:

Web server config

If you're familiar with hosting web servers and/or reverse proxies, follow this:

  1. Expose port 3000 in your Docker run config (e.g. -p 81:3000 maps the host machine's port 81 to the container's port 3000)
  2. If you want to access the Captcha solving page from outside your network, setup any port forwarding/reverse proxy/DNS
  3. Set the webPortalConfig.baseUrl in the config

Localtunnel setup

If you don't have the ability to port forward/reverse proxy on your network, you can still access the web server remotely by setting:

{
  "webPortalConfig": {
    "localtunnel": true,
  },
}

in your config.json.

Notifications

Each notification method has unique setup instructions. Read its documentation (notification methods) on the config site for exact details and instructions. The example config may also help as an example.

Testing notification and web server

Since user actions may not always be required, the notification methods and web server can be manually tested. Essentially, you just need to add:

  "testNotifiers": true,

to the root of your config.json. For more details check out the config docs. Note: to optimize for standby memory usage, the web server does not run when the process is not running. The web server will only be available during a scheduled run.

Docker Configuration

This image is available from both GitHub Container Registry and Docker Hub:

If you're experiencing issues with Chromium starting (hangs on login/notification), you can try the Debian image:

If you are using full JSON configuration, the only remaining Docker configurables are the port and volume.

Environment Variables

Most configuration options can be set via environment variable. Look for the env tag in the config docs for each option's key.

If for whatever reason you want to change the default config directory or config file name, CONFIG_DIR and CONFIG_FILE_NAME are available as environment variables.

Ports

Host port Container port Description
3000 3000 Port mapping on which the web server hosting the captcha solving page resides

Volumes

Host location Container location Mode Description
/my/host/dir/ /usr/app/config rw Location of the config and cookie file(s)

Memory Limit

It's recommended to add -m 2g as a docker run parameter to set a max memory usage of 2GB. The Chromium processes can sometimes run away, and without a limit your system can eventually lock up.

Docker Run

With JSON Config

$ docker run -d -v /my/host/dir/:/usr/app/config:rw -p 3000:3000 -m 2g ghcr.io/claabs/epicgames-freegames-node:latest

Without JSON Config

Without JSON config, you can only configure one account.

$ docker run -d -e TZ=America/Chicago -e EMAIL=example@gmail.com -e RUN_ON_STARTUP=true -e BASE_URL=https://example.com -e SMTP_HOST=smtp.gmail.com -e SMTP_PORT=587 -e EMAIL_SENDER_ADDRESS=hello@gmail.com -e EMAIL_SENDER_NAME="Epic Games Captchas" -e EMAIL_RECIPIENT_ADDRESS=hello@gmail.com -e SMTP_SECURE=true -e SMTP_USERNAME=hello@gmail.com -e SMTP_PASSWORD=abc123 -v /my/host/dir/:/usr/app/config:rw -p 3000:3000 -m 2g ghcr.io/claabs/epicgames-freegames-node:latest

Cookie Import

If you're experiencing issues logging in with device code auth, you can import cookies for a temporary session.

  1. Setup the container per the below instructions
  2. In your web browser, log in to the Epic Games Store with "Remember me" checked.
  3. Install the EditThisCookie browser extension.
  4. While viewing the Epic Games Store page, open the EditThisCookie extension window, change the URL to https://www.epicgames.com/id, and click the export button: EditThisCookie export button
  5. In your mounted ./config folder, create <email_address>-cookies.json (e.g. me@example.com-cookies.json), and paste in your cookies.
  6. Start the container and the cookies will automatically be converted to a new format.

Cookie Import Notes

Miscellaneous

v4 to v5 Migration

In v5, several options have been added or removed. The added/removed options should not affect existing v4 configs, but may need to change your config.json for a stable solution.
