Etherpad: A real-time collaborative editor for the web

About

Etherpad is a real-time collaborative editor scalable to thousands of simultaneous real time users. It provides full data export capabilities, and runs on your server, under your control.

Try it out

Etherpad is extremely flexible providing you the means to modify it to solve whatever problem your community has. We provide some demo instances for you try different experiences available within Etherpad. Pad content is automatically removed after 24 hours.

• Rich Editing - A full rich text WYSIWYG editor.
• Minimalist editor - A minimalist editor that can be embedded within your tool.
• Dark Mode - Theme settings to have Etherpad start in dark mode, ideal for using Etherpad at night or for long durations.
• Images - Plugins to improve provide Image support within a pad.
• Video Chat - Plugins to enable Video and Audio chat in a pad.
• Collaboration++ - Plugins to improve the really-real time collaboration experience, suitable for busy pads.
• Document Analysis - Plugins to improve author and document analysis during and post creation.
• Scale - Etherpad running at scale with pad sharding which allows Etherpad to scale to ∞ number of Active Pads with up to ~20,000 edits per second, per pad.

Installation

Requirements

Node.js >= 12.17.0.

GNU/Linux and other UNIX-like systems

Quick install on Debian/Ubuntu

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt install -y nodejs
git clone --branch master https://github.com/ether/etherpad-lite.git &&
cd etherpad-lite &&
src/bin/run.sh

Manual install

You'll need Git and Node.js installed.

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

1. Move to a folder where you want to install Etherpad.
2. Clone the Git repository: git clone --branch master https://github.com/ether/etherpad-lite.git
3. Change into the new directory containing the cloned source code: cd etherpad-lite
4. Run src/bin/run.sh and open http://127.0.0.1:9001 in your browser.

To update to the latest released version, execute git pull origin. The next start with src/bin/run.sh will update the dependencies.

Windows

Prebuilt Windows package

This package runs on any Windows machine. You can perform a manual installation via git for development purposes, but as this uses symlinks which performs unreliably on Windows, please stick to the prebuilt package if possible.

1. Download the latest Windows package
2. Extract the folder

Run start.bat and open http://localhost:9001 in your browser.

Manually install on Windows

You'll need Node.js and (optionally, though recommended) git.

1. Grab the source, either:
   • download https://github.com/ether/etherpad-lite/zipball/master
   • or git clone --branch master https://github.com/ether/etherpad-lite.git
2. With a "Run as administrator" command prompt execute src\bin\installOnWindows.bat

Now, run start.bat and open http://localhost:9001 in your browser.

Update to the latest version with git pull origin, then run src\bin\installOnWindows.bat, again.

If cloning to a subdirectory within another project, you may need to do the following:

1. Start the server manually (e.g. node src/node/server.js)
2. Edit the db filename in settings.json to the relative directory with the file (e.g. application/lib/etherpad-lite/var/dirty.db)
3. Add auto-generated files to the main project .gitignore

Docker container

Plugins

Etherpad is very customizable through plugins.

Available Plugins

For a list of available plugins, see the plugins site.

Plugin Installation

You can install plugins from the admin web interface (e.g., http://127.0.0.1:9001/admin/plugins).

Alternatively, you can install plugins from the command line:

cd /path/to/etherpad-lite
# The `--no-save` and `--legacy-peer-deps` arguments are necessary to work
# around npm quirks.
npm install --no-save --legacy-peer-deps ep_${plugin_name}

Also see the plugin wiki article.

Suggested Plugins

Run the following command in your Etherpad folder to get all of the features visible in the above demo gif:

npm install --no-save --legacy-peer-deps \
  ep_align \
  ep_comments_page \
  ep_embedded_hyperlinks2 \
  ep_font_color \
  ep_headings2 \
  ep_markdown \
  ep_webrtc

For user authentication, you are encouraged to run an OpenID Connect identity provider (OP) and install the following plugins:

• ep_openid_connect to authenticate against your OP.
• ep_guest to create a "guest" account that has limited access (e.g., read-only access).
• ep_user_displayname to automatically populate each user's displayed name from your OP.
• ep_stable_authorid so that each user's chosen color, display name, comment ownership, etc. is strongly linked to their account.

Next Steps

Tweak the settings

You can modify the settings in settings.json. If you need to handle multiple settings files, you can pass the path to a settings file to src/bin/run.sh using the -s|--settings option: this allows you to run multiple Etherpad instances from the same installation. Similarly, --credentials can be used to give a settings override file, --apikey to give a different APIKEY.txt file and --sessionkey to give a non-default SESSIONKEY.txt. Each configuration parameter can also be set via an environment variable, using the syntax "${ENV_VAR}" or "${ENV_VAR:default_value}". For details, refer to settings.json.template. Once you have access to your /admin section, settings can be modified through the web browser.

If you are planning to use Etherpad in a production environment, you should use a dedicated database such as mysql, since the dirtyDB database driver is only for testing and/or development purposes.

Secure your installation

If you have enabled authentication in users section in settings.json, it is a good security practice to store hashes instead of plain text passwords in that file. This is especially advised if you are running a production installation.

Please install ep_hash_auth plugin and configure it. If you prefer, ep_hash_auth also gives you the option of storing the users in a custom directory in the file system, without having to edit settings.json and restart Etherpad each time.

Customize the style with skin variants

Open http://127.0.0.1:9001/p/test#skinvariantsbuilder in your browser and start playing!

Development

Things you should know

You can debug Etherpad using src/bin/debugRun.sh.

You can run Etherpad quickly launching src/bin/fastRun.sh. It's convenient for developers and advanced users. Be aware that it will skip the dependencies update, so remember to run src/bin/installDeps.sh after installing a new dependency or upgrading version.

Read our Developer Guidelines

HTTP API

Etherpad is designed to be easily embeddable and provides a HTTP API that allows your web application to manage pads, users and groups. It is recommended to use the available client implementations in order to interact with this API.

OpenAPI (previously swagger) definitions for the API are exposed under /api/openapi.json.

jQuery plugin

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

Plugin Framework

Etherpad offers a plugin framework, allowing you to easily add your own features. By default your Etherpad is extremely light-weight and it's up to you to customize your experience. Once you have Etherpad installed you should visit the plugin page and take control.
