Get started

From zero to a deployed project on a persistent cloud environment, in a few steps.

Prerequisites#

• A Host4.ai account (the Free plan is enough to start)
• An idea you want to build, described in plain English

1. Launch an environment#

Create an account and start an environment. You get a persistent Ubuntu server with Claude Code and Codex already installed - no setup, no dependency wrangling.

2. Describe what to build#

Use the AI Builder (default model: Claude Sonnet 4) and describe your idea in plain English. The agent scaffolds, builds, and iterates on the project inside your environment.

3. Work in the terminal or over SSH#

Open the browser terminal for a zero-setup shell, or connect over SSH to use your own editor and dotfiles. You have full root on the machine.

4. Deploy#

Your project goes live immediately on a <name>.host4.ai subdomain. Add a custom domain whenever you like - SSL is handled for you.

Expected result#

A running, deployed project on an environment that keeps working 24/7 - and code you can pull down over git or SSH at any time.

Next: pick the right plan.
