Is it open source? Do they disclose which framework they use for the GUI? Is it Electron or Tauri?

lol ofc not

looks like the same framework they used to build chatgpt desktop (electron)

edit - from another comment:

> Hi! Romain here, I work on Codex at OpenAI. We totally hear you. The team actually built the app in Electron specifically so we can support Windows and Linux as well. We shipped macOS first, but Windows is coming very soon. Appreciate you calling this out. Stay tuned!
