The last sentence in their philosophy section reads "

Nest.js is more like feathers, actix for rust, flask, lumen, etc... it's not as opinionated iirc last time I played with it... so there's not a specific way everything is organized like a rails or laravel project... if I were doing node it'd probably be nest, but w/ swoole/octane and knowing laravel inside/out I'm gonna lose time/productivity switching to anything else, so I stick w/ what I know.
