Codex Usage Tracker

Local-first usage analytics for the Codex app.

Codex Usage Tracker reads your local Codex app logs and generates a private dashboard for token usage, estimated Codex credits, API-equivalent cost estimates, project breakdowns, terminal reports, and optional WakaTime ai coding time.

Why

AI coding tools can burn through tokens, but it is hard to answer basic questions:

• Which project used the most tokens?
• Which thread was the most expensive?
• How much active Codex time did I spend today?
• How much of my input was cached?
• Can my Codex app activity show up in WakaTime?

This tool gives you those answers locally, without uploading Codex transcripts to another service.

Features

• Reads local Codex app rollout logs from ~/.codex
• Generates HTML, CSV, and JSON reports
• Prints daily, weekly, monthly, session, project, and model terminal reports
• Estimates Codex credits from input, cached input, and output tokens
• Shows API-equivalent USD estimates for rough comparison
• Includes doctor and demo commands for first-run confidence
• Supports date filters with --days, --since, --until, and --timezone
• Supports share-safe output with --redact and --hash-projects
• Sends optional WakaTime ai coding heartbeats
• Works without an OpenAI API key

Install

Clone the repo:

git clone https://github.com/SuvenSeo/codex-usage-tracker.git
cd codex-usage-tracker

Run directly with Python:

python codex_app_tracker.py report

Or install the CLI locally:

pip install -e .
codex-usage-tracker report

Quick Start

Check your machine:

codex-usage-tracker doctor

Generate the full local dashboard:

codex-usage-tracker report

Open:

out/dashboard.html

Try a safe public demo:

codex-usage-tracker demo

That writes synthetic reports to out/demo/.

CLI Reports

Global scope and privacy flags go before the command:

codex-usage-tracker --days 7 daily
codex-usage-tracker --since 2026-05-01 --until 2026-05-24 weekly
codex-usage-tracker --timezone Asia/Colombo monthly
codex-usage-tracker session --limit 10 --compact
codex-usage-tracker project --format json
codex-usage-tracker model --format csv

Create a share-safe report:

codex-usage-tracker --redact --hash-projects report

WakaTime

WakaTime sync is optional. It requires wakatime-cli and a normal ~/.wakatime.cfg file.

Generate reports and sync recent Codex activity:

codex-usage-tracker run --sync-wakatime

The tracker sends conservative heartbeats with:

• category: ai coding
• entity type: app
• project name/folder
• timestamp

It does not send prompts, responses, transcripts, or token totals to WakaTime.

On Windows, you can install a scheduled task:

.\install_scheduled_task.ps1

Remove it:

.\uninstall_scheduled_task.ps1

Output

By default, reports are written to out/:

• dashboard.html
• codex_usage_summary.json
• threads.csv
• daily.csv
• projects.csv
• models.csv

Do not commit generated reports. They can include private local paths, project names, thread titles, and usage details unless you use privacy flags.

Cost Estimates

The tracker reports exact local token counts where Codex logs provide them.

Cost estimates are not an invoice:

• estimated_codex_credits uses OpenAI's Codex token-based rate card.
• estimated_api_usd_equiv uses public OpenAI API prices as an equivalent estimate.
• Real Codex billing/credit balance should be checked in Codex Settings > Usage or OpenAI billing.

Pricing can change. Review and update MODEL_RATES in codex_app_tracker.py when OpenAI updates rates.

Privacy

This is a local parser. It reads from ~/.codex and writes local reports.

Use --redact to hide thread titles, local folders, and log paths. Use --hash-projects to replace project names with stable anonymous labels.

See docs/PRIVACY.md before sharing dashboards or CSV files.

Comparison

Tool	Best For	Difference
Codex Usage Tracker	Codex app users who want local reports and WakaTime sync	Codex-specific, dependency-light, private generated dashboard
ccusage	Multi-agent terminal usage reports	Broader agent support and mature CLI reporting
agentsview	Local multi-agent session intelligence	Richer local web app and session indexing
codex-wakatime	Codex CLI WakaTime hook	Focused time tracking, not token/cost dashboards

The near-term goal is to be the simplest local-first Codex usage dashboard, then expand only after the Codex workflow feels solid.

Development

Run checks:

python -m py_compile codex_app_tracker.py
python -m unittest discover -s tests -v

Build package artifacts:

python -m pip install build
python -m build

Roadmap

See docs/ROADMAP.md.

Built By

Built by SuvenSeo for developers who want local visibility into Codex usage.

Status

Early alpha. Codex local log formats may change, so parser compatibility can break. Issues and PRs are welcome.
