tokentap tracks token usage for LLM CLI tools with a live terminal dashboard. See exactly how many tokens you're using in real-time.

Why tokentap?

• Track Token Usage: See exactly how many tokens each request consumes
• Monitor Context Windows: Visual fuel gauge shows cumulative usage against your limit
• Debug Prompts: Automatically saves every prompt as markdown and JSON for review
• Zero Configuration: No certificates, no setup - just install and go

Installation

pip install tokentap (We are working on this one)

Or install from source:

git clone https://github.com/jmuncor/tokentap.git
cd tokentap
pip install -e .

Requirements

• Python 3.10+

Quick Start
