Spill · Menu bar app for macOS

Spill keeps one icon in the menu bar. Click it for a small panel with your Mac's status, the tokens your coding agents used, Caffeine and window controls.

Your Mac and your AI usage, one click away.

Spill keeps one icon in the menu bar. Click it for a small panel with your Mac's status, the tokens your coding agents used, Caffeine and window controls.

CPU, memory and storage at a glance.

Click the menu bar icon and the panel opens with three parts: status, AI usage and window controls. Each status row shows the current value, one line of detail and a chart of the last 24 readings.

CPU

Usage and load, with a bar for each core that turns yellow, orange and red as the core fills up.

Memory

Share in use, memory pressure and how much is still available.

Storage

How much of the startup disk is used and how much is left.

Network

Download and upload speed, drawn as two lines.

GPU

GPU usage and the number of GPU cores.

In the menu bar

Click a row for details. CPU, memory and network can also sit in the menu bar as text or a chart.

See what your agents used.

Spill reads the token usage that Codex, Claude Code and Antigravity leave on your Mac. The Token Metering card in the panel opens the dashboard: how much of each limit is left, totals by day, input and cache use, which models ran and which agents are running now. Moru reads the same numbers, so you can check usage without leaving a task.

Caffeine

Keep the Mac awake for a set time, or until you turn it off.

Window controls

Move the focused window to a half, a corner, the centre or another display with Control + Option shortcuts.

Asks only for what it uses

Accessibility is requested only when you turn on window controls. Spill never asks for Screen Recording and leaves other apps' menu bar icons alone.

Stored on your Mac

Usage is kept in a local SQLite store on your Mac.
