What is host4.ai?
host4.ai rents small Linux environments where Claude Code or OpenAI Codex can keep working on a project after you close your laptop, and adds a prompt-based website builder on top. It suits developers and hobbyists who want an agent and hosting in one place.
You can type an idea into the builder, choose a style and color scheme, and get a live site on a host4.ai subdomain, or open the browser terminal and run Claude Code or Codex directly. Every environment includes SSH and full Linux access, and projects can be exported at any time.
The free tier gives one site and 20 agent messages, after which you connect your own Anthropic account. Paid plans raise CPU, memory, storage and traffic, add custom domains, and extend limits in $5 blocks instead of stopping the agent. Add-ons include a dedicated IP and email inbox.
