Install the Starplex CLI

The Starplex CLI connects your coding agents to Starplex. One command installs it for your user account. It doesn't need administrator access.

• macOS or Linuxwith a shell such as bash or zsh
• Node.js 26 or laterwith npm, on your PATH
• An invitationto a Starplex organization, to sign in afterward

1. Run the installer

   Paste this into your terminal. It downloads the CLI from Starplex and puts the starplex command in ~/.local/bin.

   curl -fsSL https://app.starplex.dev/install.sh | sh

   It's done when the last line reads Starplex CLI installation finished, followed by the build and where it put the command.
   It says Node 26 or later is required

   The installer checks your Node version first and changes nothing if it's too old. Install Node 26 or later with your version manager, open a new terminal, and run the installer again.

2. Check the command is on your PATH

   Check that your shell can find the command:

   starplex --version

   You'll see one line naming the CLI's version and the build that was installed.
   command not found: starplex

   The installer prints this fix when ~/.local/bin isn't on your PATH. Add this line to your shell profile, such as ~/.zshrc, then open a new terminal:

   export PATH="$HOME/.local/bin:$PATH"
