If you're running Claude Code, Cursor, and a few custom API scripts simultaneously, you probably have no idea what you're actually spending on tokens. Checking three separate billing pages at the end of the week is nobody's idea of a good time.
Tokemon is a new open-source terminal tool that solves this by reading the log and cache files these AI coding tools already generate on your machine. It parses them, deduplicates requests so nothing gets double-counted, and displays everything in a single live dashboard.
The main command, tokemon top, launches a TUI (terminal user interface) with sparklines showing daily and weekly usage trends. Think of it like htop for your AI token spend. You leave it running in a terminal pane and glance at it when you want to know how your budget is holding up.
Supported Tools and Setup
- Claude Code log file parsing
- Cursor cache and log parsing
- Custom API scripts with compatible logging
The tool is written in Rust and installs via Cargo (cargo install tokemon). No API keys needed for Tokemon itself since it reads local files rather than hitting billing APIs.
The deduplication feature is worth highlighting. If you're running Claude Code through Cursor, or if multiple tools hit the same API endpoint, Tokemon catches the overlap and avoids inflating your numbers.
For anyone whose monthly API bill has crept past the "I should probably track this" threshold, Tokemon fills a gap that the providers themselves haven't bothered to address. Most AI tool dashboards show you usage for their platform only. Nobody gives you the combined view. Now a free terminal tool does.
