Codex Multi-Account Usage

English · 한국어

Token usage & estimated cost for every OpenAI Codex account — in your VS Code status bar.

Sibling to Claude Multi-Account Status Bar: same idea, for OpenAI Codex. It reads each account's session logs locally (no network calls, no credentials) and shows today's estimated spend per account.

Today's spend, right in the status bar (with a breathing 🦘 wallaby):

Hover for tokens & cost — today / 7 days / all logs:

Features

• N accounts, side by side — leave the list empty and it auto-detects .codex* dirs in your home (each is a CODEX_HOME). Labels are the folder name as-is.
• Token cost — today / 7-day / all-logs tokens and estimated cost in the hover tooltip; today's spend on the status bar.
• Local & private — reads only <CODEX_HOME>/sessions/rollout-*.jsonl token counts. No API calls, no auth.json/credential access.
• Breathing wallaby mascot — a tiny mascot before each account (toggle off if you like).

Data source

Per account, usage comes from <CODEX_HOME>/sessions/rollout-*.jsonl: the token_count events (total_token_usage) are summed by day. Cost is computed client-side from configurable per-million rates.

Cost is an estimate, not your bill — it's the API-equivalent value of your exact token counts. Adjust codexUsage.pricing.* to match current OpenAI pricing.

ℹ️ Because it reads local session logs, the numbers reflect what you did on this machine. Codex usage from other computers isn't summed in.

Install

• VS Code — Marketplace: search "Codex Multi-Account Usage", or ext install QG-devramyun.codex-usage-bar.
• Cursor / Windsurf / VSCodium — Open VSX: search the same name in the extensions panel.
• From VSIX: download from Releases → code --install-extension codex-usage-bar-0.1.0.vsix.

Configure (settings.json)

"codexUsage.accounts": [
  { "label": ".codex",      "dir": "~/.codex" },
  { "label": ".codex-work", "dir": "~/.codex-work" }
  // leave empty to auto-detect
],
"codexUsage.refreshIntervalSeconds": 30,
"codexUsage.pricing.inputPerMillion": 1.25,
"codexUsage.pricing.cachedInputPerMillion": 0.125,
"codexUsage.pricing.outputPerMillion": 10

dir is each account's CODEX_HOME (~, %VAR%, ${env:VAR} expand). Left-click an item to refresh.

Multi-account, the Codex way

Codex reads its config/data from the dir named by CODEX_HOME (default ~/.codex) — just like Claude Code's CLAUDE_CONFIG_DIR. Run Codex with different CODEX_HOME values (~/.codex, ~/.codex-work, …) and each gets its own login; this extension shows them all.

Not included (yet)

Rate-limit / weekly-quota %, API calls, and a full cost dashboard are out of scope for now — this is a focused, local, cost-only first version.
