Deploy and Host Prompt Optimizer on Railway

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

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.
