codexU macOS Usage Tracker

Skill by ara.so — Codex Skills collection.

codexU is a native macOS menu bar and desktop application for monitoring OpenAI Codex / ChatGPT Codex and Claude Code usage. It provides real-time quota tracking (5-hour and 7-day windows), token usage analytics, project rankings, skill/tool usage stats, and a today task board. All data is read locally from ~/.codex/ and ~/.claude/ without uploading to third-party services.

What codexU Does

• Quota Monitoring: Displays 5-hour and 7-day quota remaining/used percentages with reset timers in the menu bar
• Token Analytics: Tracks uncached input, cached input, and output tokens with API cost equivalency estimates
• Task Board: Generates today's task board from local Codex threads and enabled automations
• Usage Trends: Shows 6-month daily token heatmap and 7-day trend summaries
• Project Rankings: Lists top projects by token usage, estimated value, thread count, and last activity
• Skill/Tool Stats: Displays most-used tools and skills from local session events
• Dual Runtime: Supports both Codex and Claude Code with global runtime switching
• Local-First: All data parsed from local SQLite and JSONL files, no external API calls for usage
