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

[mag123c]

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.
