Getting Started

Online Version

The easiest way to start using Silex is by using the online version provided by Silex Labs foundation. Simply visit editor.silex.me and start building your website right away.

Desktop App (beta)

There is a desktop application that you can install on your computer which may be faster since it uses your local files and it works offline. You can download the desktop app from the Silex desktop repository.

Local or Server Installation

You can also run Silex locally or on your server using npx, npm, or Docker.

Check the developer docs for configuration options and integration with your js projects.

Using npx

npx @silexlabs/silex

This command will run Silex with default config.

Using Docker

docker run -p 6805:6805 silexlabs/silex

This command will run Silex in a Docker container.

Using npm

First, install Silex as a dev dependency in your project:

npm install --save-dev @silexlabs/silex

Then, you can run Silex with the silex command in your package.json scripts:

  "scripts": {
    "start": "silex"


You can configure Silex using environment variables and command-line options. All available options can be found in the developer docs as well as in the code: src/ts/server/cli.ts.

Check the example config files - which are the same as plugins in Silex, in the examples/ folder. To test these configs, start Silex locally like this:

$ npx silex --client-config=./examples/client-config-transformers.js --server-config=`pwd`/examples/server-config-plugins.js 

Or like this:

$ SILEX_CLIENT_CONFIG=./examples/client-config-transformers.js SILEX_SERVER_CONFIG=`pwd`/examples/server-config-plugins.js npm run start:debug
