Radial app

Install & setup

One terminal command takes a fresh Mac to a working Radial setup. The command installs the app; Radial's built-in setup assistant then walks you through every tool and sign-in, under your own accounts.

One command

curl -fsSL https://radial.to/install | sh

This downloads the latest signed and notarized Radial app, installs it to Applications, and opens it. Nothing else: no sudo, no credentials, no extra tools. If you have Node already, the npm wrapper runs the same installer:

npx radial-setup

Prefer clicking? Download the DMG from radial.to/download and drag Radial to Applications, like any Mac app.

The setup assistant

On first launch Radial checks your machine and shows a short checklist with a Run button per step. Each command executes in Radial's built-in terminal where you can watch it, and every sign-in opens your browser to authorize your account. Radial never sees or stores those credentials; see AI accounts & terms.

• Your agent. Claude Code is the recommended default, installed with Anthropic's official installer and signed in with claude login. Codex and Cursor work the same way if you prefer them.
• GitHub. The GitHub CLI installs via Homebrew when you have it, or as the official standalone binary when you don't. During gh auth login Radial puts the one-time code on your clipboard for you.
• Vercel (optional). For deploy previews and shipping to production: vercel login under your own Vercel account.
• git and Node. If git is missing, Radial triggers Apple's own Command Line Tools installer (Apple owns that dialog and download). If Node is missing, Radial can install a private copy just for running your dev servers.

The checklist lives in Settings, so you can finish any step later or re-check after installing something yourself.

Manual setup

Everything the assistant does, as plain commands. All of them are the tools' official installers and put binaries in ~/.local/bin or Homebrew's prefix; Radial finds both.

Claude Code (recommended agent):

curl -fsSL https://claude.ai/install.sh | bash
claude login

An ANTHROPIC_API_KEY environment variable works too, instead of signing in.

Codex, if you prefer it:

npm i -g @openai/codex && codex login

Cursor, if you prefer it:

curl https://cursor.com/install -fsS | bash && cursor-agent login

GitHub CLI:

brew install gh
gh auth login --git-protocol https --web

Vercel CLI (optional):

npm i -g vercel && vercel login

git, if a fresh Mac asks for it:

xcode-select --install

Requirements

• macOS on Apple Silicon.
• Everything else (agent CLI, GitHub CLI, git, Node) can be installed by the setup assistant, so a factory-fresh Mac is fine.
