Use cases

Long-running autonomous agents#

A remote dev box you actually own#

Use Host4.ai as a full root Ubuntu machine you reach over SSH or a browser terminal - your editor, your dotfiles, your packages - without provisioning cloud infra yourself.

From idea to live URL fast#

Describe a project to the AI Builder, let it build, and deploy to a live .host4.ai subdomain in one flow - custom domain and SSL when you are ready.

Try agents without local setup#

Spin up an environment with Claude Code and Codex preinstalled to evaluate agent workflows, with nothing to install on your own machine.
