# Orcylo

> Your Claude Code and Codex limits in the Mac menu bar, with a countdown to each reset and alerts at 80 % and 95 %. Plus about 25 apps, not 700 processes.

- What it is: a native menu bar system monitor for macOS 15 Sequoia and later, on Apple silicon and Intel. It groups about 700 processes under the ~25 apps that own them, with CPU, memory, GPU, power, disk and network per app, and Quit or Force Quit after a confirmation.
- History: 30 days, one point per minute for every metric and the busiest apps, stored on the Mac.
- Alerts: when an app burns CPU for minutes, its memory keeps growing, it writes heavily to disk, memory pressure turns critical or the disk fills up.
- Menu bar: one item per metric (CPU, Memory, GPU, Network, Disk, Thermals, Power, Claude, Codex) as a value, graph, both or a ring; the dropdown has a tab per metric, Busiest Right Now, and volume and brightness sliders.
- Claude Code: exact 5-hour and weekly limits from Claude Code's status line through a small bridge that keeps your status line running, reset countdowns, pace, and alerts at 80 % and 95 % and on reset. It never reads the Claude login.
- Codex: exact plan limits (5-hour and weekly) and tokens from its session logs, credits and limit alerts. Cursor, Antigravity and Gemini CLI are detected and linked to their dashboards.
- Projects: dev servers grouped by project folder, with their ports, memory and how long they have been idle; Orcylo asks before stopping one.
- Hardware: GPU, disk and network per app, system power or battery health, 38 temperature sensors, fan speed (read-only), sound output and Bluetooth device batteries.
- Not included: fan control and per-app volume.
- Price: €5 for the first 20 licences, then €7.50 for the next 30, then €9.99 (19 left at €5). One payment, a lifetime licence with every future update. No subscription.
- Licence: one licence activates Orcylo on one Mac at a time; move it in Settings → License.
- No free trial: buy once, then download and paste the licence key. No account.
- Buying: sold through Dodo Payments, the merchant of record (payment, tax, invoices). Purchases are final; legal rights and billing errors are the exceptions.
- Support: support@orcylo.app
- Requirements: macOS 15 Sequoia or later · Apple silicon and Intel.
- Privacy: no account and no tracking. Orcylo goes online only for licence and update checks and for services you connect. The website counts visits with Google Analytics: cookie-free until a visitor accepts, and not loaded at all for a visitor who declines.
- Language: English (dates and numbers follow the Mac's region).
