I actually think that RedwoodJS is more in spirit of Rails than Blitz and it does include a lot of boilerplate generation. But yeah, Blitz does have a CLI as well:
https://blitzjs.com/docs/cli-overview
So something like creating an instance of an existing model definition and trying out its methods instead of CLI for running a database migration or generating a stubbed model definition.
Now I’m certainly going to be trying Blitz.
