While this is true, this project seems to wrap it up in a CLI package for starting and stopping projects. Whereas starting devcontainers, at least as far as I have seen, is always done via VSCode or IDE, so while it technically could be called CLI too, would be a lot more complicated than this project.
The devcontainers cli has existed for a while. Definitely not as smooth as using with vscode but it has all the main points.
