Deploy and Host Open WebUI on Railway

Open WebUI is a self-hosted, feature-rich chat interface for running AI models locally or via API. It works with Ollama for local LLMs and OpenAI-compatible APIs — giving you a polished ChatGPT-like experience with full data privacy and zero per-seat fees.

About Hosting Open WebUI

Hosting Open WebUI requires running its Python-based web server alongside persistent storage for chat history, user accounts, and settings. By default it uses SQLite — no separate database needed. The app reads its configuration from environment variables at startup: your OpenAI API key or Ollama base URL, auth settings, and a secret key for session management. On Railway, the service deploys from a Dockerfile with a single click and gets a public HTTPS URL automatically.

Common Use Cases

• Running a private, self-hosted ChatGPT alternative that works with any OpenAI-compatible API
• Connecting a team to a shared Ollama instance with a polished multi-user chat UI
• Experimenting with local LLMs (Llama 3, Mistral, Phi) through a browser without touching the terminal

Dependencies for Open WebUI Hosting

• AI Provider — either an OpenAI API key (OPENAI_API_KEY) or a running Ollama instance (OLLAMA_BASE_URL)
• Secret Key — a random string for session signing (WEBUI_SECRET_KEY); generate with openssl rand -base64 32

Deployment Dependencies

• Open WebUI Documentation
• Open WebUI GitHub Repository
• Open WebUI Environment Variables Reference
• Ollama — for running local LLMs
