codex-stats

codex-stats is a local analytics tool for coding agents.

It reads local session data from every coding assistant installed on the machine and surfaces:

a browser dashboard with an Overview tab for every tool combined, plus one tab per tool (Codex, OpenCode, Claude Code, Hermes)
day, week, month, and all-time windows inside every tab
model and project breakdowns
recent session history
estimated token-based cost (or each tool's own recorded cost when available)
per-tool cost overrides and a stacked per-tool token trend on the Overview
anomaly-aware usage insights and recommendations
file-level impact tracking: a "Most Edited Files" panel showing per-file edit counts and add/delete line totals parsed from Codex and Claude Code rollouts
export for cross-device snapshots
shareable JPG cards and browser PDF export from the dashboard

Data Sources

Each source is detected automatically and skipped when no data is present:

Tool	Location	Notes
Codex	`~/.codex`	`state_5.sqlite` + rollout JSONL files
OpenCode	`~/.local/share/opencode/opencode.db`	recorded cost + tokens per session
Claude Code	`~/.claude/projects/*/.jsonl`	per-project transcripts
Hermes	`~/.hermes/state.db`	recorded cost + tokens per session

Use these environment variables to point at non-default locations (also used for test isolation):

CODEX_HOME (Codex), CODEX_STATS_OPENCODE_HOME (OpenCode), CODEX_STATS_CLAUDE_PROJECTS_DIR (Claude), CODEX_STATS_HERMES_HOME (Hermes)

Install

pipx install codex-stats

Or with pip:

python3 -m pip install codex-stats

Command Reference

codex-stats Generate a standalone dashboard HTML file and open it in the default browser.
codex-stats --output codex-stats-dashboard.html Write the dashboard HTML to a fixed path.
codex-stats --output codex-stats-dashboard.html --no-open Write the dashboard HTML without opening the browser.
codex-stats --source codex --source opencode Restrict the dashboard to the given tool scopes (repeat the flag to pick multiple).
codex-stats export codex-stats-export.json Export normalized local stats to JSON.
codex-stats export codex-stats-export.json --since 30d Export only a rolling window of recent sessions.

Inside the dashboard, use the action bar to:

switch tools with the Overview / Codex / OpenCode / Claude Code / Hermes tab row
switch between Day, Week, Month, and All Time inside the active tool
print the active tool and window to PDF
download shareable JPG cards for summary, cost, focus, and project share

How It Works

codex-stats does not proxy or intercept API traffic. It reads local artifacts: Codex state_5.sqlite and rollout files, the OpenCode database, Claude Code project transcripts, and the Hermes database, then normalizes everything into one session model.

Notes

Costs are estimates by default. When a tool records its own cost (OpenCode, Hermes), that value wins for the session. Per-tool rates can be set in ~/.config/codex-stats/config.toml:
```
[pricing.source_usd_per_1k_tokens]
codex = 0.01
opencode = 0.01
claude = 0.015
hermes = 0.008
```
Output depends on local file formats remaining compatible.
export --since Nd limits snapshots to a rolling window before sharing.

Roadmap

The current priority list lives in docs/roadmap.md.

Shareable Assets

The dashboard exports JPG cards with names like:

These sample assets were generated from the current renderer so the docs match what the dashboard actually downloads.

Development

For local development from the repo:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -U pip setuptools
python -m pip install -e .

Run without installing:

PYTHONPATH=src python3 -m codex_stats
