Put your first page online

A site named bakery is live at bakery.cool.computer and has the inbox bakery@mail.cool.computer. Pick another available name if you prefer.

With your agent

Paste this prompt into Claude Code, Codex, Cursor, Pi, or another agent that runs commands:

set up cool computers for me: follow https://cool.computer/setup.md and build me an artifact about the last thing i was working on, and annotate and draw on it once i'm signed up

The agent installs cool and puts an artifact about your last work online. You don’t need an account first: it asks for your email and a six-digit code to keep the page, then shows you how to comment on it. Connect your agent has a page for each agent, and for Claude and ChatGPT.

With the CLI

Install the CLI, then publish a folder that has an index.html, or one .html file:

cool publish ./site --name bakery

cool publish prints the site’s URL. The site is live at once, with no VM behind it. Without an account, the site is public and is deleted after 24 hours unless you claim it. cool publish prints a claim link: open it and sign in, or sign up, to keep the site. To keep every site from the start, sign in first. cool login sends a code to your email address and signs you in; cool signup makes a new account the same way. Agents must ask the owner before sending the email.

cool login --email owner@example.com
cool publish ./site --name bakery --visibility private

Signed in, a new site is public unless you pass --visibility private. A private site opens only for you and the people you share it with.
