Codex-X is a cross-platform desktop management tool built with Tauri 2, React 18, and Rust, designed to provide a centralized graphical interface for OpenAI Codex desktop and CLI users. The tool addresses the fragmentation of configuration files by consolidating prompt injection, API provider management, session synchronization, and Skills/MCP configurations into a single UI. Users can manage prompt templates—including five built-in specialized templates for tasks like CTF, reverse engineering, and software development—using "append" or "replace" injection modes, with automatic backups performed before writes. For connectivity, it allows managing multiple named official Codex logins and third-party API providers via TOML/JSON, supporting connection testing and model retrieval. Session management features include searching, grouping by project path, and bulk deletion of local chat histories. Additionally, the tool provides visual oversight of Skills and MCP (Model Context Protocol) settings, enabling easy activation/deactivation and ZIP-based installation. Codex-X also includes a usage statistics dashboard that tracks token consumption by date and model, including sub-agent usage aggregated into parent sessions. It is available for macOS (Apple Silicon/Intel), Windows (EXE/Portable), and Linux, utilizing a local SQLite database for metadata storage.
