One command. Sixty seconds. Done.

Install theSolid# CLI

Paste the command for your OS. The installer handles Node, the CLI, your editor wiring, shell completion, and your first login — all without you typing another character.

macOS

curl -fsSL https://solidnumber.com/install.sh | sh

Linux

curl -fsSL https://solidnumber.com/install.sh | sh

Windows (PowerShell)

iwr -useb https://solidnumber.com/install.ps1 | iex

What the installer actually does

Every step is idempotent — safe to re-run. Nothing landed on your machine that you can't see.

1
Verifies Node 20+
Installs Node 20 LTS via fnm (macOS/Linux) or winget (Windows) if missing. Skips if already present.
2
Installs @solidnumber/cli globally
npm install -g @solidnumber/cli@latest — pulls the same package the docs reference.
3
Opens the browser to log you in
Standard OAuth-style flow. The token lands in ~/.solid/config.json and never leaves your machine.
4
Wires Claude Code (if installed)
Adds a SessionStart hook so .claude/CLAUDE.md auto-refreshes every Claude session. Detects via `which claude`.
5
Installs shell tab-completion
Auto-detects bash / zsh / fish / PowerShell and writes the completion script to the canonical path.
6
Prints next steps
Three commands you can run: scaffold a business (52 industry templates), pull an existing company, or spin up a live demo.

Source is public

Read install.sh or install.ps1 before you pipe to your shell. We expect you to.

Idempotent

Re-run any time to upgrade. Detects existing installs, skips work that's already done, never duplicates.

Agent-ready

Auto-wires MCP for Claude Code / Cursor / Codex when detected. JSON error envelope is on by default in v2.0.

Already have the CLI?

Re-run the installer to upgrade, or use npm directly:

npm i -g @solidnumber/cli@latest

CLI Docs Quickstart SDKs

Manual install (no curl-pipe-shell)

If your security policy forbids piping a remote script to your shell, install in two steps:

# 1. Install Node 20+ from https://nodejs.org
# 2. Install the CLI
npm install -g @solidnumber/cli@latest

# 3. Login + wire your editor
solid auth login
solid install              # Claude Code SessionStart hook
solid completion install   # bash / zsh / fish / PowerShell
