Codex CLI is a TUI app, but Codex App is an actual desktop GUI app. If you actually look at the TFA, you'll see that all of the videos are of the desktop app.

Codex is both a macOS app and a CLI/TUI app.

Their naming is not very clear. The codex desktop app is somewhat of a frontend for the codex cli.

By the look and feel of it I would guess it is written with Electron.

> Codex is a rust TUI app, and it's available as open source. It has nothing to do with Electron.

I just updated Codex and looked inside the macOS app package. It is most definitely still an Electron app.

the codex desktop app is electron, as is claudes
