It has some basic features that are 'in-house' like a login, everything else seems to be using third party API's. As per the longer article :

> Eleven Labs API for text-to-speech conversion

> streamio-ffmpeg gem for audio file analysis

> Active Storage integration for audio file management

> OpenAI integration for recipe generation

etc. I'm not saying it's not a fun excersize in 'vibe coding', I'm just very curios the quality of the code that was actually produced. Its my feeling project maintainability is something that will be a big pain point in the future is people are relying on these tools.. 35k LOC for this recipe app smells like that to me at least.
