host4.ai is cloud hosting with an AI builder attached. Describe what you want in plain English and it builds and deploys the project; behind that sits a real persistent Linux environment with root, SSH, a browser terminal and a file manager, running Claude Code or OpenAI’s Codex. Deployment goes to a .host4.ai subdomain or a custom domain with automatic SSL.
Giving the agent a persistent machine rather than an ephemeral sandbox is the difference that matters. Most AI builders regenerate a project from scratch on every prompt, which is fine until you need to install a package, inspect a log or fix something by hand – at which point the abstraction ends and there is nowhere to stand. Root on a box that stays up means the AI-built project and a normal server are the same thing.
RP NET MEDIA hosts it in Germany. A free trial gives 1 vCPU, 1GB RAM, 5GB and 20 messages; Pro is $13.75 a month or $165 a year for 2 vCPU and 2GB; Business is $44.92 or $539 for 4 vCPU and 4GB; add-ons cover custom domains at $12, dedicated IP at $4 and email at $5. There is also a $99 lifetime deal capped at 200 spots – treat a lifetime deal on a hosting product with the caution it deserves, since the costs recur even if the revenue does not. Resources are modest at every tier, and the AI messages are metered separately from the compute.
