The idea for remote-codex came from being able to control my Codex sessions remotely through the ChatGPT app on a phone or tablet, but not through chatgpt.com in a regular browser. I wanted that access on a large screen, with the whole browser window available to follow the work.
I wanted an overview of Git changes, what was happening in each session, how much of the context window was in use, and token usage. I wanted more of the available information in the interface, along with the ability to start new sessions directly from the browser.
The Codex server allows sessions to continue without an open terminal. So I built a browser interface on top, where I could start sessions, return to them and follow their progress on a full screen. That became remote-codex.
