Self-hosted n8n · local installer

Install Relmio on your computer.

Connect a compatible self-hosted n8n setup from your own computer. Relmio inspects the target first and changes nothing until you approve the exact plan.

Choose the command for your terminal. Copy and run it on your computer.

macOS / Linux

curl -fsSL https://relmio.jpfusin.tech/install.sh | sh

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

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.

PowerShell

irm https://relmio.jpfusin.tech/install.ps1 | iex

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

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.jpfusin.tech/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.

NPX

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

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

Install details

Dashboard commands

A persistent Homebrew or global npm install adds relmio start, relmio status, relmio open and relmio stop.

Stop ends only Relmio's dashboard process. It never stops n8n or a managed companion.

Runtime and Node.js

Direct installers reuse Node.js 24 or newer when it is installed. Otherwise they download and verify a temporary official runtime, run the one-shot wizard in the foreground and remove that runtime afterward.

NPX needs Node.js 24 or newer.

Homebrew and WinGet

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.

Sign-in and tokens

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.

ChatGPT/Codex sign-in tokens expire. The Codex authentication guide describes automatic refresh but gives no fixed lifetime, and Relmio's bridge refreshes its own copy. Read the authentication guide (opens in a new tab)
