One number per plan or budget.

Each entry shows how much is used. It turns orange near the limit and red past it. Click for the rest.

Features

Everything in one menu.

Limits

Plan limits

Claude Pro and Max, and Codex on a ChatGPT plan: every window with its reset time, live from the provider, so other machines count too.

Pace

A small meter shows whether you are on pace, behind, or about to run out before the reset. ↑ marks an entry that burns fast.

A notification that a budget crossed 80%

Alerts and colors

Orange near the limit, red past it, and a notification when usage crosses your thresholds, 80% and 100% by default.

Budgets

A Vertex account with its spend against a monthly budget

Budgets you set

Pay-per-token spend on Vertex or the OpenAI API, against your own weekly or monthly budget.

Settings, Groups tab, with a shared monthly company budget

Shared budgets

Several accounts under one budget, like a monthly limit your company sets.

Settings, Prices tab, with the Import menu

Prices you control

A built-in price table, one-click imports from LiteLLM, CSV import and export, and your own overrides. Every import shows a preview first.

Your setup

The details table with tokens per model and a per-day trend

Details on demand

Tokens per model, project and harness, with a per-day trend, folded away until you need them.

Settings, Menu Bar tab, with the live preview of the bar

Your bar, your way

Pick the entries and their order with a live preview. Show levels as colored text, as a pill, or not at all.

The details table by harness: Claude Code, Codex and OpenCode

Three agents, one view

Claude Code, Codex and OpenCode. An account stands for who pays, so Vertex spend from Claude Code and OpenCode lands in one budget.

And the small things

Works offline. The last good values survive a restart and a missing network, marked ~ when they may be out of date.
Adaptive refresh. Refreshes less while you are away, in Low Power Mode or when the Mac runs hot, and right away when you open the menu.
Verified updates. One click installs a new release after checking its checksum, signature and notarization. Homebrew installs are recognized.
Sign-in alerts. A notification when an agent’s sign-in stops working.
One JSON file. Settings write a plain configuration file that you can edit by hand.

Privacy

Your data stays on your Mac.

Your agents’ own sign-in, read only
To show plan limits, AgentTacho reads the sign-in tokens Claude Code and Codex already have, and sends each one only to that provider’s usage endpoint. It never refreshes or changes a login.
No browser, no cookies
It never opens your browser’s data or its cookies. Token counts and spend come from the files your agents write on this Mac.
No telemetry
Besides asking Anthropic and ChatGPT for your plan limits, the only automatic request is the update check, which you can turn off. Price lists download only when you ask.
Every read written down
The README lists each file and keychain item AgentTacho reads, what for, and what it keeps.

Compare

How it compares.

CodexBar covers far more providers. AgentTacho covers fewer, lets you set a budget for any pay-per-token account, shares one budget across accounts, and keeps the menu bar to one line.
