Usage Planner (formerly Codex4ever) is a planner for your OpenAI Codex weekly quota. It shows when your quota runs out at your current pace, whether a predicted extra reset is likely to arrive first, and when a banked reset is worth redeeming.

Unofficial; not affiliated with OpenAI. MIT licensed.

Pick a strategy

Ask once in Codex and the planner opens beside the chat. Pick a strategy and the plan changes: daily usage, refills and run-out points.

[Switching to Keep available and Weekdays only updates the plan; scrolling down shows the planned refills]

What it does

• Timeline of your next two weeks — daily usage, remaining quota, run-out points, outages, normal refreshes and banked-reset uses, one column per day.
• Extra-reset forecast — the chance of an automatic reset in the next 48 hours, the likely window, and a second reset conditioned on the first, built from public reset history and Tibo's public posts.
• Five strategies — Keep pace (your current pace: see when quota runs out), Keep available, Use it all (empty quota just before the next refill), Weekdays only, Weekend focus.
• Codex plugin — reads your local, signed-in quota and banked resets, plans in the conversation, and opens the same visual planner.

How it plans

• A predicted reset is counted only when it is at least 60% likely before the refresh in effect, and it is placed at a conservative time (where it has most probably already happened), not at its single most likely hour. You can switch the count to 0, 1 or 2 on the timeline.
• Every refill restarts the seven-day window — a banked reset, an extra reset or the normal refresh.
• Banked resets: extras cover outages, earliest expiry first; the last one is kept for a real outage (24 h or more), and a bank about to expire can be used rather than wasted.
• One rule everywhere: the website, the plugin page and the plugin's MCP tools always give the same plan for the same inputs.

The forecast is an uncalibrated model estimate, not a promise. Usage Planner never redeems a reset or spends credits for you.

Use it

Codex plugin (Node.js 20+ and a signed-in Codex app or CLI):

codex plugin marketplace add ItsOdeLeo/usage-plannercodex plugin add usage-planner@usage-planner

Start a new Codex chat and ask: "Open quota planning." Reading your quota is local and read-only; no separate API key is needed.

Other MCP clients (Claude Code, Claude Desktop, Cursor and others): the same server is on npm as usage-planner and in the MCP Registry as io.github.ItsOdeLeo/usage-planner. Reading your quota still needs a signed-in Codex CLI on the same machine.

{ "mcpServers": { "usage-planner": { "command": "npx", "args": ["-y", "usage-planner"] } } }

Website: usageplanner.com, no install. Enter your quota by hand; everything is calculated in your browser and your inputs are not sent anywhere.

Run locally:

npm installnpm run web          # http://127.0.0.1:4173/npm test

Data sources

Public reset data comes from Codex Resets, including the bundled offline archive (npm run archive:refresh). Thanks to its maintainer. With an optional X API token, Tibo's full timeline is read directly from X.

Development

.github/workflows/deploy-site.yml rebuilds the static site every 30 minutes and deploys it to Cloudflare Pages. Optional settings (LLM classification of posts, X timeline access) are listed in .env.example; keys are only read at build time and never reach the browser.
