Nitro is a command-line tool for managing Docker-based PHP development environments. Like most development environments, Nitro provides several defaults to improve the developer experience of using Docker. A primary focus of Nitro is “Simplicity matters,” meaning the developer should be focused on building their project, not getting bogged down in the DevOps swamps. If you avoid local container development environments because you don’t care about DevOps, Nitro is a great place to start your container experience.
