Overview

Codex-X is a powerful, cross-platform desktop and CLI management tool designed for OpenAI Codex. It centralizes and visualizes high-frequency operations, eliminating the need for manual file edits. Manage your prompts, custom prompts, third-party API providers, session synchronization, Skills/MCP, and TOML configurations all within an intuitive graphical interface.

Key Features

• Visual Prompt Injection & Management: Organize prompts by category, import Markdown, customize, and enable/disable with a single click. Includes 5 built-in templates and syncs 6 more from GitHub for software development and writing assistance.
• Prompt Injection Modes: Choose between "Append Original Prompt" to add your custom prompts or "Replace Original Prompt" for complete template switching, ideal for diverse tasks and models.
• Provider/API Management: Seamlessly manage multiple official Codex logins and third-party API providers. Features one-click copying, switching, connection testing, model retrieval, and import from cc-switch.
• Session Management: Synchronize, check, search, and delete local sessions. Organize your Codex history by project path for a cleaner workflow.
• Skills/MCP Visualization: Centralized management of Skills and MCPs, including import, installation from ZIP, enabling/disabling individual components, and update status checks.
• TOML & Auth Configuration: View and edit config.toml and auth.json directly. Supports enabling the 1M context window directly from the UI (model dependent) and automatically backs up critical configurations.
• Usage Statistics: Monitor local token usage by date and model, view daily trends, cache hit rates, model distribution, and the top 10 recent sessions. Sub-agent usage is attributed to their parent sessions.
• Cross-Platform Compatibility: Available for Windows (MSI/Portable), macOS (Apple Silicon/Intel), and Linux (deb/rpm/AppImage). Offers in-app updates for installed versions.
