d9

d9 is a command line tool that automates setting up local Drupal development environments using Docker. You run one command and it builds the containers, installs Drupal, and configures the database for you. It is built specifically for Drupal 9 and 10 projects, removing the manual steps of configuring LAMP stacks or MAMP.

The tool handles MySQL or MariaDB databases, supports custom PHP versions, and integrates with Composer for dependency management. It is written in Go and uses Docker Compose under the hood. You can define project settings in a simple YAML file, making it repeatable across teams. It works on Linux, macOS, and Windows through Docker Desktop.

d9 is open source under the MIT license and maintained by LaWebcapsule, a French web agency. It is best suited for Drupal developers who want fast, isolated local environments without managing virtual machines or manual server configs. The project is relatively new but actively maintained on GitHub.
