wzchav/tokentab is an open-source command-line interface tool that analyzes session logs from AI coding assistants like Claude Code, Codex, and Gemini CLI to calculate token usage and associated costs. The tool helps developers track and optimize their spending when using various AI coding services by parsing the session history files these services generate during usage.
What it is
This Python-based utility is designed to work with the log files created by popular AI coding assistants during interactive sessions. When developers use tools like Claude Code, Codex, or Gemini CLI, these applications generate detailed session logs that contain information about the prompts submitted and responses received. wzchav/tokentab processes these logs to extract token counts and calculate the corresponding costs based on the pricing models of each service.
The tool provides developers with visibility into their AI usage patterns, helping them understand which types of operations consume the most tokens and where they might optimize their workflows to reduce costs. By analyzing historical session data, it can generate reports showing usage trends and cost breakdowns across different time periods or project types.

How it compares
wzchav/tokentab occupies a specific niche in the developer tooling ecosystem, focusing exclusively on cost analysis for AI coding assistants. Unlike general-purpose CLI tools or comprehensive AI platform dashboards, it specializes in parsing and analyzing the specific log formats generated by services like Claude Code, Codex, and Gemini CLI. While some AI platforms provide built-in usage dashboards, this tool offers an independent, open-source alternative that can work across multiple services and provide more granular analysis of local session logs.
