A development environment is any copy of your site that operates separately from the live site. Development environments allow you to make changes, try new modules, write new code, and test new ideas, on a copy of your site instead of the real thing, ensuring those changes happen in a sandbox where you’re not affecting anyone trying to use the live version of your application.
This is typically done by installing the server software required to run Drupal on your own computer and then creating a clone of your existing database and files. Or you might have a separate instance of the site setup on the existing infrastructure.
Here’s a basic recipe for setting up a new development environment:
- Install web server, database server, PHP, and Git
- Either install Drupal if starting from scratch, or clone the code, database, and user-generated files from your live site
- Clear the cache
Example tasks
- Install Drupal on, or copy an existing site to, your computer to do development
- Test modules and code without affecting the production site
- Test server configuration changes on your localhost before deploying them to production
Confidence
There are dozens of ways to do this, and none is the only right way. The bare minimum requirement is that you have PHP, a web server, and a database running on the computer where you would like to install Drupal. Beyond that, it’s mostly personal preference.
Drupalize.Me resources
If you want our recommendation, on the Drupalize.Me team, we all use DDEV as a local development environment. Learn how to install Drupal locally with DDEV in this tutorial:
Installing Drupal using the instructions in this tutorial will give you a working Drupal site that can be used for learning, or real-world project development.
Before you can work on a Drupal site locally (on your computer), you'll need to set up a local development environment. This includes all the system requirements like PHP and a web server, that Drupal needs in order to run. Our favorite way to accomplish this is using DDEV.
In this tutorial we'll learn:
- How to install and configure DDEV for use with a Drupal project.
- How to use DDEV's integrated Composer to download Drupal and Drush.
- How to install Drupal inside DDEV so you can access the site and start doing development.
By the end of this tutorial, you should be able to set up a local development environment for learning Drupal or working on a new Drupal project.
What is a development site? These tutorials from the Drupal User Guide will help you understand what you need in a local development environment, in order to run Drupal locally on your machine.

Learn to use Docker for Drupal Development:
Docker
TopicFor the Drupal developer, Docker is a way to provide a local development environment to run web server software.
Note: DDEV uses Docker, so unless you want to get into the details of how to customize Docker containers, we recommend using DDEV as a local development environment for Drupal.
Set up your environment for theming in Drupal:
Making Drupal fast by default implies having caching layers and CSS and JavaScript aggregation utilities enabled out-of-the-box. As a theme developer this can be annoying, because you must clear these various caches in order to preview any changes. In addition, inspecting variables with debugging tools often produces PHP errors. We'll make some recommendations for PHP settings on your local environment that can prevent these errors from happening so often.
By the end of this tutorial, you should be able to:
- Set up your local Drupal site for theme development
- Prepare your local development environment for working on and debugging themes
