Install Relmio on your computer.

Connect to a compatible self-hosted n8n setup, inspect the target, then approve the exact companion plan only when it matches.

Showing the macOS / Linux installation command.

relmio / macOS / Linux

curl -fsSL https://relmio.vercel.app/install.sh | sh

For macOS, Linux, WSL, or Git Bash. Runs a foreground one-shot wizard; no preinstalled Node.js required.

relmio / Homebrew

brew tap Demonbane18/relmio && brew trust --formula Demonbane18/relmio/relmio && brew install relmio

For macOS or Linux with Homebrew. Trusts only the Relmio formula, then installs Relmio and Node.js.

relmio / PowerShell

irm https://relmio.vercel.app/install.ps1 | iex

For Windows PowerShell or PowerShell 7. Runs a foreground one-shot wizard; no Git Bash or preinstalled Node.js required.

relmio / CMD

for /f "delims=" %F in ("%TEMP%\relmio-install-%RANDOM%-%RANDOM%-%RANDOM%.cmd") do @if exist "%~F" (exit /b 80) else curl -fsSL --remove-on-error https://relmio.vercel.app/install.cmd -o "%~F" && set "RELMIO_SELF_DELETE=%~F" && call "%~F"

For Command Prompt, not PowerShell. This non-admin bootstrap verifies a temporary runtime when Node.js 24+ is unavailable and runs as a foreground one-shot wizard.

relmio / NPX

npx --yes --ignore-scripts relmio@latest

For any local terminal that already has Node.js 24 or newer.

Safety, credentials, and runtimeWhat the wizard uses and what it leaves untouched

Where it runs

Run Relmio on your own computer, not inside the n8n container. Direct installers reuse Node.js 24+ when available or download and verify a temporary official runtime. They run a foreground, one-shot wizard and remove any downloaded runtime afterward. NPX requires Node.js 24+.

Dashboard commands

A persistent Homebrew or global npm install supports relmio start, relmio status, relmio open, and relmio stop. Stop affects only Relmio's dashboard process; it never stops n8n or a managed companion.

Existing n8n boundary

Discovery starts read-only. Relmio does not edit, rebuild, or restart your existing n8n container, and it stops for fingerprint, plan, and final write confirmation.

Credential boundary

Relmio 0.14.0 handles provider OAuth only. Codex and SuperGrok keep separate sign-in sessions. Experimental SuperGrok setup works with local apps and private local or VPS n8n companions without a ChatGPT credential.

Packages and sessions

Homebrew is public through Demonbane18/relmio. Its installer command trusts only the Relmio formula, not the whole tap. WinGet remains hidden until Microsoft accepts the catalog pull request and the public catalog updates. ChatGPT tokens expire, but the official client refreshes active sessions; OpenAI publishes no fixed 10-day lifetime. Read the authentication guide.
