OpenAI just dropped their Cursor killer

OpenAI released Codeex, a new AI coding tool combining CLI, web app, and desktop application for managing AI agents across projects. Unlike traditional code editors, it provides a GUI for orchestrating multiple parallel coding tasks, with features like work trees, cloud environments, automations, and cross-project thread management. The tool shares history between CLI and app, supports multiple editors, and enables developers to manage several concurrent development tasks simultaneously. While work tree implementation has limitations and environment variable management needs improvement, the orchestration layer represents a shift from direct code editing to agent management workflows.
