Overview

Codex-X is a powerful, cross-platform desktop and CLI management tool for OpenAI Codex. It centralizes and visualizes critical aspects of your Codex workflow, eliminating the need for manual file edits and streamlining complex configurations. Manage prompts, API providers, sessions, skills, and TOML settings all within an intuitive graphical interface.

Key Features

• Visual Prompt Management: A central hub for managing all your prompts. Import .md files, categorize them, create custom prompts, and toggle them on/off with ease. Supports 11 prompt templates, including 5 built-in offline sets and 6 synchronized from GitHub. Offers two enabling modes: "Append Original Prompt" and "Replace Original Prompt" for flexible workflow switching.
• Provider/API Switching: Seamlessly manage multiple OpenAI official logins and third-party API providers. Test connections, fetch models, and switch between providers with a single click. Integrates with cc-switch for efficient import of existing configurations.
• Session Synchronization & Management: Search, organize, and synchronize your local Codex sessions. Group sessions by project path, check their status against the current provider, and perform bulk deletions with confidence (with built-in warnings for permanent actions).
• Skills/MCP Visualization: Centralized management for Codex Skills and MCPs. View, import, enable/disable, and check for updates to your extensions directly within the application.
• TOML Configuration & Auth: Visualize and edit config.toml and auth.json files within the UI. Supports enabling the 1M context window directly from the provider editing page and automatically backs up critical configurations before writing.
• Usage Statistics: Monitor your token usage by date and model, visualize daily trends, and understand model distribution. Sub-agent usage is attributed to the main session.
• Cross-Platform Compatibility: Available for Windows (MSI/Portable), macOS (Apple Silicon/Intel), and Linux (deb/rpm/AppImage). Offers in-app updates for installed versions.

Typical Use Cases

• Streamlined Prompt Engineering: Quickly switch between different prompt strategies for coding, security research, technical writing, or general tasks without manual file manipulation.
• Multi-Provider API Management: Effortlessly manage API keys and endpoints for both OpenAI and various third-party providers, ensuring you're always connected to the optimal service.
• Organized Project Workflows: Keep your Codex sessions organized by project, making it easy to revisit past conversations and configurations.
• Efficient Skill Integration: Manage and deploy your Codex Skills and MCPs efficiently, accelerating your ability to extend Codex's capabilities.
• Simplified Configuration Tuning: Visually adjust config.toml settings, including context window size, and manage authentication details without deep dives into configuration files.
• Performance Monitoring: Track your token consumption to optimize costs and understand how different models are being utilized.
