tokenusage (tu)

Fast Rust CLI/TUI/GUI token usage tracker for Codex usage and Claude Code usage.

tu scans local session logs and gives one merged token + cost view across Codex and Claude in CLI, live monitor, and GUI.

Benchmark: up to 131.1x faster than ccusage on warm runs (34.5x on cold runs) with real local Codex logs. See full benchmark.

Install

cargo (crates.io)

cargo install tokenusage --bin tu

npm

npm install -g tokenusage

cargo-binstall (prebuilt binary)

cargo binstall tokenusage --no-confirm

Quick Start

tu
tu live
tu gui
tu img --output tokenusage-share.png                 # daily view (today, hourly bars)
tu img --period weekly --output tokenusage-week.png  # weekly view (daily bars)

Why tokenusage

• Faster feedback loop: native Rust + parallel scan/parsing + incremental cache.
• One dashboard for both Codex and Claude, with merged totals and per-model breakdown.
• Share-ready image card (tu img) for posting your token/cost trend.
• Works in terminal and desktop GUI without sending your logs to a cloud service.

FAQ

Where does the data come from?

From local log directories only:

• Claude: ~/.config/claude/projects, ~/.claude/projects
• Codex: ~/.codex/sessions, ~/.config/codex/sessions

You can override with --claude-projects-dir and --codex-sessions-dir.

How is cost estimated?

tu uses OpenRouter pricing when available, caches it for 6 hours, and falls back to built-in offline rates when network pricing is unavailable.

Is my data private?

Yes for usage logs: parsing is local. tu only requests pricing metadata unless you run --offline.

Benchmark Details

Benchmark setup:

• Machine: Apple M3 Max, macOS 15.6.1
• Dataset: ~/.codex/sessions (71 JSONL files, ~537 MB), date range 2025-09-01 to 2026-02-28
• tu version: 1.1.2
• @ccusage/codex version: 18.0.8
• Both in default mode (online pricing behavior, network enabled)

Results:

• Cold-run speedup: about 34.5x
• Warm-run speedup: about 131.1x

Notes: results vary by hardware, filesystem cache state, and log volume.
