# Server configuration: 
##########################

APP_TITLE=LibreChat

# The server will listen to localhost:3080 by default. You can change the target IP as you want. 
# If you want to make this server available externally, for example to share the server with others 
# or expose this from a Docker container, set host to 0.0.0.0 or your external IP interface. 
# Tips: Setting host to 0.0.0.0 means listening on all interfaces. It's not a real IP.  
# Use localhost:port rather than 0.0.0.0:port to access the server. 
# Set Node env to development if running in dev mode.
HOST=localhost
PORT=3080

# Note: the following enables user balances, which you can add manually
# or you will need to build out a balance accruing system for users.
# For more info, see https://docs.librechat.ai/features/token_usage.html

# To manually add balances, run the following command:
# `npm run add-balance`

# You can also specify the email and token credit amount to add, e.g.:
# `npm run add-balance example@example.com 1000`

# This works well to track your own usage for personal use; 1000 credits = $0.001 (1 mill USD)

# Set to true to enable token credit balances for the OpenAI/Plugins endpoints
CHECK_BALANCE=false

# Automated Moderation System
# The Automated Moderation System uses a scoring mechanism to track user violations. As users commit actions
# like excessive logins, registrations, or messaging, they accumulate violation scores. Upon reaching
# a set threshold, the user and their IP are temporarily banned. This system ensures platform security
# by monitoring and penalizing rapid or suspicious activities.

BAN_VIOLATIONS=true # Whether or not to enable banning users for violations (they will still be logged)
BAN_DURATION=1000 * 60 * 60 * 2 # how long the user and associated IP are banned for
BAN_INTERVAL=20 # a user will be banned everytime their score reaches/crosses over the interval threshold

# The score for each violation

LOGIN_WINDOW=5 # in minutes, determines the window of time for LOGIN_MAX logins
REGISTER_MAX=5 # The max amount of registrations allowed per IP per REGISTER_WINDOW
REGISTER_WINDOW=60 # in minutes, determines the window of time for REGISTER_MAX registrations

# Message rate limiting (per user & IP)

LIMIT_CONCURRENT_MESSAGES=true # Whether to limit the amount of messages a user can send per request
CONCURRENT_MESSAGE_MAX=2 # The max amount of messages a user can send per request

LIMIT_MESSAGE_IP=true # Whether to limit the amount of messages an IP can send per MESSAGE_IP_WINDOW
MESSAGE_IP_MAX=40 # The max amount of messages an IP can send per MESSAGE_IP_WINDOW
MESSAGE_IP_WINDOW=1 # in minutes, determines the window of time for MESSAGE_IP_MAX messages

# Note: You can utilize both limiters, but default is to limit by IP only.
