codex-stats 1.1.0

Local AI usage observability CLI for Codex sessions.

codex-stats

codex-stats is a local analytics CLI for Codex usage.

It reads your local Codex state from ~/.codex and surfaces:

• session summaries
• rolling usage totals across today, week, month, or the last N days
• model and project breakdowns
• project-specific drilldowns
• recent session history
• estimated token-based cost
• anomaly-aware usage insights and recommendations
• export and import for cross-device snapshots
• merged export snapshots for multi-device rollups
• shareable weekly and monthly reports

Install

pipx install codex-stats

Or with pip:

python3 -m pip install codex-stats

• codex-stats top --project backend-api Show the largest sessions for one project.
• codex-stats costs Show estimated cost totals and monthly projection.
• codex-stats insights Show anomaly-aware insights and recommended next steps.
• codex-stats doctor Validate local Codex data sources and config.
• codex-stats doctor --strict Return a non-zero exit code if any doctor check fails.
• codex-stats init Create a default config file under ~/.config/codex-stats/.

• codex-stats export codex-stats-export.json --since 30d Export only a rolling window of recent sessions.
• codex-stats import laptop.json desktop.json Read one or more exported snapshots and summarize them.
• codex-stats merge merged.json laptop.json desktop.json Merge multiple exported snapshots into one deduplicated file.
• codex-stats merge merged.json laptop.json desktop.json --json Merge snapshots and return a machine-readable merge summary.
• codex-stats completions zsh Print shell completion setup for your shell.
• codex-stats --color always Force ANSI color output.
• codex-stats --json Return machine-readable JSON output for supported commands.

How It Works

codex-stats does not proxy or intercept Codex API traffic.

It reads local Codex artifacts, including:

• state_5.sqlite for session metadata
• rollout JSONL files for request and token snapshots

Notes

• Costs are estimates, not billing values.
• Output depends on local Codex file formats remaining compatible.
• export and import let you move normalized snapshots between machines.
• merge lets you deduplicate and combine exported snapshots into one file.
• export --since Nd limits snapshots to a rolling window before sharing.
• doctor --strict is useful in scripts and CI because it returns a non-zero exit code on failed checks.
• --color auto|always|never controls ANSI styling.

Pricing Config

Optional pricing config lives at ~/.config/codex-stats/config.toml.

[pricing]
default_usd_per_1k_tokens = 0.01

[pricing.model_usd_per_1k_tokens]
gpt-5.4 = 0.02
gpt-5-mini = 0.005

To create the config file automatically:

codex-stats init

To inspect the effective config:

codex-stats config show
codex-stats config show --json

JSON Schemas

Machine-readable output is intended to stay stable across patch releases.

• summary JSON: time-window totals such as sessions, requests, tokens, cost estimate, and top model
• report JSON: period, optional project scope, summary, comparison, projects, top sessions, costs, and insights
• export JSON: schema_version, exported_at, and normalized sessions
• doctor JSON: a list of checks with name, ok, detail, and severity
• config JSON: config path, whether the file exists, pricing defaults, overrides, and display defaults
• import and merge JSON: import summary plus deduped session counts

Full field documentation lives in docs/json-schema.md.
