Deploy and Host Chuanhu Chat on Railway

Chuanhu Chat (ChuanhuChatGPT) is a web UI for ChatGPT and many other LLM APIs: chat history, file-based Q&A, web search, prompt templates and model switching in one interface.

About Hosting Chuanhu Chat

This template runs the official tuchuanhuhuhu/chuanhuchatgpt:latest image (Gradio UI on port 7860). The start command writes a config.json that turns on login, so the public URL is not open to strangers: sign in as admin with the password in the service's CHUANHU_PASSWORD variable (generated at deploy). To use the app, add an OPENAI_API_KEY variable (or DEEPSEEK_API_KEY, GOOGLE_GENAI_API_KEY, and so on) and redeploy, or paste a key in the UI settings after login.

Chat history is kept inside the container and resets on redeploy.

Common Use Cases

A private ChatGPT-style interface on your own API key
Ask questions about uploaded documents (PDF, Word, text)
Compare several LLM providers from one UI

Dependencies for Chuanhu Chat Hosting
