What is codex-x?

Codex-X is a desktop application for people who use OpenAI's Codex desktop app or Codex CLI and want a visual way to manage everything around it, instead of hand editing config files. It runs on Windows, macOS, and Linux, and is built with Tauri, React, TypeScript, and Rust, storing data locally with SQLite. The core feature is prompt template management. Codex-X ships with five built in prompt templates covering things like general coding tasks and more specialized workflows aimed at security research and reverse engineering, and it can sync additional templates from the project's GitHub repository. Users can also import their own Markdown prompt files, organize prompts into categories, write custom descriptions, and turn any individual prompt on or off like a plugin. When enabling a prompt, you choose whether it appends to your existing instructions or fully replaces them, and the app automatically creates a backup each time you toggle one. Beyond prompts, Codex-X lets you manage API providers: saving multiple third party API endpoints alongside the official OpenAI connection, testing connections, fetching available models, and importing existing provider settings from a related tool called cc-switch. It also offers session management, letting you search, group by project path, sync, and permanently delete local Codex chat sessions, with a clear warning that deletion cannot be undone. The app additionally provides a visual interface for Codex's Skills and MCP extensions, letting you view what is installed, import configurations, install a Skill from a ZIP file, and enable or disable each one individually. Finally, it centralizes viewing and editing of Codex's own configuration files, including config.toml and the authentication file that distinguishes an official login from third party API keys. The project is dual language, with both Chinese and English README versions, and is released under the MIT license.
