Question: What is the default port for Open WebUI?

Answer:

The default port for Open WebUI (the application itself) is 8080.

• When running via Docker (the most common method), the container listens on port 8080 internally.
  • Typical command: docker run -d -p 3000:8080 ...
  • This maps host port 3000 (or any port you choose) → container port 8080.
  • You access it at http://localhost:3000 (or whatever host port you mapped).
• When running directly via Python/pip (open-webui serve), it also listens on port 8080 by default.
  • You access it at http://localhost:8080.

You can change the port using the PORT environment variable (e.g., -e PORT=9999 in Docker) or the --port flag when using the serve command.

The version shown in your message (v0.5.10) is quite old — current versions (as of 2026) still use 8080 as the default internal/container port.
