Show HN: Track your Codex CLI(5.3) token spending (also Claude Code and Gemini) (github.com)

I've been tracking my AI CLI spending across Claude Code, Codex CLI, and Gemini CLI. Existing tools either don't support Codex at all or break on newer models like gpt-5.3-codex.

So I built toktrack. One command

npx toktrack

What you get: - Per-model cost breakdown (gpt-5.3-codex, Opus, Sonnet, Gemini, etc.) - Daily/weekly/monthly trends - 52-week heatmap - Works across all three major AI CLIs

Built in Rust with simd-json. Scans 3500+, 4GB+ session files in ~40ms.

It also caches independently, so even after Claude Code deletes sessions (default 30 days), your cost history is preserved.
