# Deploy and Host Prompt Optimizer on Railway

[Prompt Optimizer](https://github.com/linshenkx/prompt-optimizer) is a web app that rewrites rough prompts into clearer, better structured ones, compares the results and works with OpenAI-compatible, Gemini, DeepSeek and other model providers.

## About Hosting Prompt Optimizer

This template runs the official `linshen/prompt-optimizer:latest` image (nginx on port 80). Open the public URL and add your own model provider and API key in the app's model settings; keys are stored in your browser, not on the server. The page is open to anyone who has the URL: to require a login, add the variables `ACCESS_PASSWORD` (and optionally `ACCESS_USERNAME`, default `admin`) in Railway and redeploy.

## Common Use Cases

- Turn short instructions into structured system and user prompts
- Compare original and optimized prompts side by side
- Offer a team-wide prompt workshop 

## Dependencies for Prompt Optimizer Hosting

- One service, no database or volume
- An API key for the LLM provider you want to use, entered in the app

### Deployment Dependencies

- [Prompt Optimizer on GitHub](https://github.com/linshenkx/prompt-optimizer)
- [Docker image](https://hub.docker.com/r/linshen/prompt-optimizer)

## Why Deploy Prompt Optimizer on Railway?

Railway gives you a public HTTPS URL and automatic restarts with no server to maintain.
