Tokn
Your coding-agent usage, always a glance away. Tokn lives in the macOS menu bar and shows Claude Code and OpenAI Codex CLI usage — session and weekly percentages, reset countdowns, and a recent burn-rate trend — without opening a single Settings tab.

Two providers, one gauge
Tracks both Claude Code and the OpenAI Codex CLI. Switch between them in the popover — the menu bar icon follows your choice.
Session & weekly at a glance
Current-session and weekly usage rings with live reset countdowns, so you never open a Settings tab to hit refresh again.
Burn-rate trend
A recent burn-rate sparkline (vs a 6-hour average) that survives restarts, plus threshold notifications as you approach your limit.
Local by default
No server, no telemetry. Claude usage goes straight from your Mac to Anthropic using Claude Code's own Keychain login; Codex reads its local logs.
Built with Tauri, Rust, React, and TypeScript. Tokn is unofficial — not made by, or affiliated with, Anthropic or OpenAI. It depends on Claude Code's Keychain format, Anthropic's usage endpoint, and Codex's local log format, any of which may change.
