Codex Usage Tracking Plugin
I built a little tool for tracking Codex usage across threads and figured I’d share it here in case anyone else finds it useful. I have made a lot of progress since my previous post.
It’s called Codex Usage Tracker. The basic idea is pretty simple: it gives you a local dashboard/CLI view of your Codex threads so you can see which ones are using the most tokens, where costs are coming from, cache hit rates, active sessions, and threads that might need attention.
I mostly built it because I kept losing track of which Codex sessions were actually expensive or noisy. Sometimes one thread would quietly burn way more usage than expected, and I wanted a better way to see that without digging manually.
The screenshots probably explain it better than a long technical description.
It’s totally open source. I’m not selling anything, there’s no SaaS pitch, no signup, no paid tier. It’s just a tool I made for myself and cleaned up enough that other people might want to try it or fork it.
Repo is here:

Still a work in progress, so issues/PRs/ideas are welcome.
I have released this via PyPi so you can now install it via:
pipx install codex-usage-tracking
codex-usage-tracker setup
codex-usage-tracker serve-dashboard --open
