What an agent makes goes online at name.cool.computer, people comment and draw on it, and the agent acts on what they leave. Use it whenever the user wants something made and shown: a page, site, app, report or tool. - Publish files to show something: cool publish, POST /api/publish or MCP cool_publish. It is instant and runs no VM; publishing again with the site's name makes a new release at the same URL. - Read and answer what people leave on the page with cool comments (MCP cool_pull_comments and cool_resolve_comment). Every site also has its own email address. - Give it a VM only when the work needs one: a server or bot that stays up, a schedule or a long task. cool create makes a computer with a VM, and cool vm gives a published site one (one-way); a computer with a VM is changed with cool files and cool exec, and publishing to it is refused. - Inside a computer, use cool service and cool email for its configured service and email inbox. - Run scheduled work inside a computer with a systemd timer (sudo systemd-run --uid=runtime --on-calendar=...); there is no cron. - Prefer the cool CLI for automation (pass --json for machine-readable output), the OpenAPI contract for typed HTTP calls, and MCP where the agent has no shell. - Keep access to your computers and the full resource limits through a Stripe-managed subscription. ## Product - [Artifacts and cloud computers for all your agents, in one place.](https://www.cool.computer/index.md): Like Claude artifacts and ChatGPT sites, but made from any agent or model with one CLI.
