Claude Code, Antigravity and Codex on your phone

Your own CLIs

Claude Code, Antigravity and Codex now run on the phone, inside a small Ubuntu in Termux. Install Termux from F-Droid or GitHub, paste one line the app shows you, and the app does the rest with the official installers. Settings has a new section, CLI sign-in, with a Sign in button for each tool. Its page opens in Chrome and the tool receives the answer on its own local address, so the app never sees a code or a token.

A signed-in tool shows up in the model list of the agent tab. Through a local MCP server it can use the phone's shell, screen control and wake-up, and every action goes through the same approvals as the built-in agent. Download and setup.

A calmer screen

The app now uses the look of the website: black and white, Barlow and Geist Mono, thin rules instead of coloured pills. The agent tab has one menu, a single status line for model, approvals and container, and a transcript that reads like the terminal on our start page. The thirteen quick buttons moved behind one slash key. Replies render Markdown instead of showing raw asterisks.

Fixed

Our pages said the app runs Node on the phone. It never did, and the text is corrected. Screens without their own background showed the grey of the Android theme; the window is black now.
