A fully functional, polished, and self-hosted web interface for Anthropic's Claude AI. This project runs entirely in your browser, using the free tier of Puter.js for secure access to the Claude API. No backend, no server costs, 100% free.
- ✅ 100% Free Access: Leverages the free tier of Puter.js to interact with the Claude API at no cost.
- 🎨 Polished UI: A clean, modern interface inspired by the official Claude UI, with light and dark mode support.
- 📄 Artifact Generation: Automatically renders code blocks into beautiful, interactive "artifact" canvases with syntax highlighting, copy, download, and even an HTML preview feature.
- 💬 Streaming Responses: Watch Claude's responses appear in real-time, just like the official experience.
- 📂 Local Chat History: Remembers your recent conversations in your browser's local storage.
- 🔐 Secure Authentication: Handles Puter.js authentication directly in the browser with a clear, user-friendly flow.
This interface does not use a pirated or reverse-engineered API. It uses the official, legitimate Puter.js library. When you first use the app, it will ask for a one-time authentication with your Puter account. This securely connects the web app to your own account's free Claude API access, ensuring everything is secure and above board.
Because browsers have security rules (CORS), you cannot simply open the index.html file directly. You must run it from a local web server. I've made this easy for you.
This project has minimal dependencies, making it very easy to set up. All you need is:
-
🐍 Python 3:
- This is only required to run the simple local web server. The application itself is 100% JavaScript.
- No
pippackages are needed. Thehttp.servermodule is included with Python by default. - Most macOS and Linux systems have Python pre-installed. For Windows, you can download it from python.org.
-
🌐 A Modern Web Browser:
- Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.
That's it! There are no other libraries or frameworks to install.
- Download: Download this project as a ZIP file and extract it.
- Run the Script: Simply double-click the
run_server.batfile. - Open: A command prompt will appear, and your default web browser will automatically open to
http://localhost:8000. That's it!
- Download: Download this project as a ZIP file and extract it.
- Open Terminal: Open your terminal or command prompt and navigate into the project folder.
- Run Server: Run the following command:
python -m http.server 8000
- Open Browser: Open your web browser and go to the address
http://localhost:8000.
First Use: The first time you send a message, a small popup will appear asking you to authenticate with Puter. Please allow the popup to enable the free AI access.
