Real time code sharing for your lectures and presentations.



Start AASTBIS 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.

User instructions

1 - Install AASTBIS globally

You must have NodeJS and NPM already installed. In your console, run:

(You may need to add sudo at start for Mac)
(You may need to run Set-ExecutionPolicy RemoteSigned first at windows powershell as administrator)

npm install -g aastbis

2 - Launch AASTBIS inside your project folder

In your console, navigate to your project folder. Then launch AASTBIS:

cd ./my-awesome-project

AASTBIS should open in your default browser and start watching any changes you make inside the folder.

3 - Share the URL with your audience

Simply share the URL that should appear and your audience will have access to your code through AASTBIS. By default, you must be on the same network.


You can add configuration arguments when calling AASTBIS.

aastbis "My project" --debug 0 --port 1234 --exclude "node_modules/**" --open true --test true --limit 200 --max-file-size 99999

And you can use shortcuts for those same arguments.

aastbis "My project" -d 0 -p 1234 -e "node_modules/**" -oti -l 200 -m 99999

All those arguments are optional. You can simply run aastbis.
