Installation

Start with your own computer.

Oysterun runs a local Host on your machine. Install the current public Host package as a normal user after Claude Code or Codex is installed for that same user, then open the phone app and pair with the login QR shown by the Host.

Linux

Create a dedicated user and install Oysterun into that user's npm prefix. Install and log in to Claude Code or Codex as this same user before running Oysterun setup. 

sudo adduser oysterun
sudo usermod -aG sudo oysterun
su - oysterun

mkdir -p "$HOME/.local/npm"
npm config set prefix "$HOME/.local/npm"
printf '\nexport PATH="$HOME/.local/npm/bin:$PATH"\n' >> "$HOME/.profile"
. "$HOME/.profile"

# Install and log in to Claude Code or Codex as this user first.
command -v claude || command -v codex

npm install -g oysterun@0.1.1 --prefer-online
oysterun --version
oysterun setup
oysterun

Node.js 20 or newer is required before running these npm commands.

Mac

With Node.js 20 or newer available, install the current public Host package after Claude Code or Codex is installed and logged in for this computer user, then run the guided setup. The Host starts locally and prints a phone login QR. 

# Install and log in to Claude Code or Codex as this user first.
command -v claude || command -v codex

npm install -g oysterun@0.1.1 --prefer-online

oysterun --version
oysterun setup
oysterun

Node.js 20 or newer is required before running these npm commands.

Update Oysterun

Use the same computer user that runs Oysterun. This installs the current public Host package, restarts the Host, and keeps your existing setup. 

npm install -g oysterun@0.1.1 --prefer-online
oysterun --version
oysterun service:restart
oysterun service:status

On Linux, keep the same npm prefix and PATH that you used during installation before running the update command.

Built for real life

AI should feel like hiring an assistant, not operating infrastructure.

Imagine your family wants help planning a trip, organizing documents, comparing insurance options, researching purchases, or managing photos. They should not need Docker, SSH, or APIs.

Local control

Your computer. Your agent.
