Our goal is to make collaborative editing the standard on the web


Etherpad lite is a really-real time collaborative editor spawned from the Hell fire of Etherpad. We're reusing the well tested Etherpad easysync library to make it really realtime. Etherpad Lite is based on node.js ergo is much lighter and more stable than the original Etherpad. Our hope is that this will encourage more users to use and install a realtime collaborative editor. A smaller, manageable and well documented codebase makes it easier for developers to improve the code and contribute towards the project.

Etherpad Lite is optimized to be easy embeddable. It provides a HTTP API that allows your web application to manage pads, users and groups. There are several clients in for this API:

There is also a jQuery plugin that helps you to embed Pads into your website

  1. Download
  2. Extract the file
  3. Open the extracted folder and double click start.bat
  4. Open your web browser and browse to http://localhost:9001. You like it? Look at the 'Next Steps' section below


As root:

  1. Install the dependencies. We need gzip, git, curl, libssl develop libraries, python and gcc.
    For Debian/Ubuntu apt-get install gzip git-core curl python libssl-dev pkg-config build-essential
    For Fedora/CentOS yum install gzip git-core curl python openssl-devel && yum groupinstall "Development Tools"

  2. Install node.js
    1. Download the latest 0.6.x node.js release from
    2. Extract it with tar xf node-v0.6*
    3. Move into the node folder cd node-v0.6* and build node with ./configure && make && make install

As any user (we recommend creating a separate user called etherpad-lite):

  1. Move to a folder where you want to install Etherpad Lite. Clone the git repository git clone 'git://'
  2. Change into the directory containing the Etherpad Lite source code clone with cd etherpad-lite
  3. Start it with bin/
  4. Open your web browser and visit http://localhost:9001. You like it? Look at the 'Next Steps' section below

Next Steps

You can modify the settings in the file settings.json

If you have multiple settings files, you may pass one to bin/ using the -s|--settings option. This allows you to run multiple Etherpad Lite instances from the same installation.

You should use a dedicated database such as "mysql" if you are planning on using etherpad-lite in a production environment, the "dirty" database driver is only for testing and/or development purposes.

You can update to the latest version with git pull origin. The next start with bin/ will update the dependencies

You know all this and just want to know how you can help? Look at the TODO list. You can join the mailinglist or go to the freenode irc channel #etherpad-lite-dev

You also help the project, if you only host a Etherpad Lite instance and share your experience with us.

Please consider using jshint if you plan to contribute to Etherpad Lite.
