localhost:3080 - LibreChat Web App Port Guide
localhost:3080
LibreChat Web App Port
Open localhost:3080Access your LibreChat interface running on port 3080
Localhost:3080 is the default web application port serving LibreChat, a widely used open-source clone that aims to meticulously replicate (and enhance upon) the original ChatGPT web experience. By hitting http://localhost:3080, developers get a fully-featured chat app supporting plugins, multiple LLM backends (Anthropic, Google, local endpoints), and secure multi-user environments.
Choosing 3080 allows the frontend app to stay out of the way of backend API ports and keeps it separated from a regular 3000 default React stack.

Services and Software That Use Port 3080
AI & Multi-Modal GUIs

When working locally, you configure a .env file to plug in varying API keys and then the 3080 container provides the user interface. Your end-users or teammates simply hit that local address to engage with the models.
How to Troubleshoot Localhost:3080
If you can’t access localhost:3080, here’s how to diagnose and fix common LibreChat server issues:
Step 1: Check if LibreChat is Running
Action: Confirm that the Docker compose stack successfully booted.
How to check: Run docker ps and look for the LibreChat container, which serves both the UI and the API, next to chat-mongodb and chat-meilisearch.
Step 2: Resolve Port Conflicts
Action: Ensure no other program is using port 3080.
How to fix: Use lsof -i :3080 (macOS/Linux) or netstat -ano | findstr :3080 (Windows) to verify availability. Since v0.8.7 the default docker-compose.yml also starts a bundled admin panel on port 3000; set ADMIN_PANEL_PORT in .env if 3000 is already taken.
Step 3: Test the Connection
Action: Verify that the local GUI is accessible.
How to test: Navigate to http://localhost:3080 in your web browser.
Common Problems and Solutions
Here are typical issues with localhost:3080 and how to resolve them:
"Something went wrong" Error
Problem: You can load the UI, but chats instantly fail with an error.
Solution: Verify your .env configurations and ensure MongoDB and Meilisearch containers are also healthy and running.
Registration Fails
Problem: Logging in or signing up a new user gives an error.
Solution: Check ALLOW_REGISTRATION in your .env: when it is false, new sign-ups are blocked (the bundled .env.example sets it to true).
