Local preview

Serve the folder over HTTP (ES modules will not load from file://):

Then open the URL shown in the terminal.

Deploy

Works as a static site on Vercel, Netlify, or GitHub Pages. Point the host at the repository root. No build step.

Configure Firebase Authentication (email/password) and Firestore for the premium dashboard. Recommended Firestore rules: allow a user to read and write only documents where uid matches request.auth.uid.

FAQ

What accounts do I need to set up before I can run this?: You need a Firebase project with Authentication (email/password) and Firestore enabled. The free tier is enough to get started. We do not include Firebase credentials; you configure your own project and add the keys to the app.
What is the tech stack?: Plain HTML, CSS, and JavaScript. The free generator runs entirely in the browser. The premium dashboard uses Firebase Authentication and Firestore. No build step, no Node dependencies.
How do I deploy this?: Deploy as a static site to Vercel, Netlify, or GitHub Pages. Point the host at the repository root. After deployment, configure your Firebase project credentials in the app so authentication and saved usernames work.
What documentation is included?: Basic documentation covering local preview, deployment, and Firebase setup. The project layout is straightforward enough that the code is the reference.
