Run Blotter on your computer.

100% free and open source. Two steps, and Blotter opens in your browser.

  1. Install rer

    The Run Edit Run command. Once per computer.

    curl -fsSL https://runeditrun.com/install.sh | sh
    export PATH="$HOME/.local/bin:$PATH"

    or npm install -g @runeditrun/rer

  2. Get Blotter and start it

    git clone https://github.com/just-every/run-blotter.git
    cd run-blotter && rer dev

    rer dev installs everything, makes you the owner and prints a link that opens Blotter signed in.

Open the link rer dev prints on this computer and confirm Finish setup. Keep that sign-in link private.

Stop Blotter when you are done: rer dev --stop
