Coffer

Run Coffer on your computer.

100% free and open source. Two lines, and Coffer opens in your browser.

  1. Install rer

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

    It installs rer for you alone, with its own Node if you have no Node 22 or later. It changes no shell settings: if it prints an export PATH=… line, run that line before step 2.

  2. Start Coffer

    rer dev just-every/run-coffer

    rer gets Coffer, installs everything, makes you the owner and prints a link that opens Coffer signed in. To start it again later: cd run-coffer && rer dev

    Already have Node 22 or later? npx -y @runeditrun/rer dev just-every/run-coffer does both steps in one line.
