Codex is OpenAI's open-source coding agent for the terminal. It works from natural-language instructions to edit code across your project, run commands, and complete tasks end to end, with its source available on GitHub under Apache-2.0. On Opper, launch it on GPT, Claude, Gemini, DeepSeek and 700+ more — one key, automatic fallbacks, and a choice of region.
CodexoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
