How it works

Close it. The work keeps going.

Let It Brew follows actual agent activity—not a timer. It keeps your Mac awake while work runs, then lets it sleep when the work stops.

Features

Keeps watch, so you don’t have to.

A focused macOS utility built around real agent state, closed-lid work, and automatic release.

Real work, not a timer

Follows each local agent’s actual lifecycle and holds the Mac only while work is happening.

Close the lid

Active agent work can keep running after the MacBook closes.

Sleeps with the work

The awake hold releases when work stops—including when an agent asks you a question.

Multiple sessions, one decision

If one session is still working, the Mac stays awake—even when another needs input.

Menu-bar only

No Dock icon or main window. Status and session controls live in the menu bar.

Local by design

No account, no cloud, no telemetry, and no notifications.

Pause whenever you want

Release Let It Brew’s hold while keeping your observed sessions visible.
