FM Chat – Apple's on-device Foundation Models, powered by Go and Wails

[ruanklein]

Hey Wails community! 👋

I've been working on FM Chat, a small macOS desktop application built with Wails and Go that provides a graphical interface for Apple's on-device Foundation Models.

The project started as a way to demonstrate another open-source project I've been working on, fmgo, a Go library that provides an idiomatic interface to Apple's native Foundation Models CLI (fm). No cloud LLM API is involved.

The architecture is essentially:

FM Chat (Wails Frontend)
  -> Go (fmgo in backend)
    -> Apple's fm Foundation Models
       -> On-device Foundation Model

I'm really happy with how well Wails fits this kind of project, especially being able to keep the application logic and AI integration in Go while still building a modern desktop UI.

Thanks to the Wails team for building such a great framework!
