A managed server where your AI coding agent runs 24/7. Persistent sessions, browser terminal, SSH access. Not a cloud IDE — a real server you control.
Start hosting Claude CodeWhen you run Claude Code locally, your agent dies when you close your terminal. Hosted Claude Code gives your agent a permanent home — a server that runs continuously with persistent storage and sessions accessible from any device.
This is not Anthropic's cloud product. Anthropic provides the AI model. host4.ai provides the server where you run it with your own API key. Your environment is completely private and isolated.
Your agent works while you sleep, eat, or commute. Come back to finished code.
Browser terminal from phone, SSH from laptop, VS Code Remote. Your choice.
Everything Claude builds is live on your domain instantly. No deploy step.
Sign up, pick a plan, and within 30 seconds you have a full Ubuntu environment with Claude Code installed. Open the browser terminal, run claude login, and start building. Close the tab whenever you want — your session persists.
Your website is served automatically on your subdomain. Everything Claude creates in your project directory is live immediately. No CI/CD, no build pipeline, no deployment commands.
