Keppler

Real time code sharing for you lectures and presentations.

What is keppler

Keppler lets you share your code during a presentation.

Start keppler inside your project folder, share the URL with your audience and start coding. Any time you save a file, viewers will receive those changes. They can browse through the files, go back in history, copy the code, download the project, preview images, chat with other viewers, ask the presenter to slow down, etc.

Instructions

1 - Install Keppler globally

You must have NodeJS and NPM already installed. In your console, run: ^{(You may need to add sudo at start)}

npm install -g keppler

2 - Launch Keppler inside your project folder

In your console, navigate to your project folder. Then launch Keppler with the name of your choice:

cd ./my-awesome-project
keppler "My awesome project"
