Pause and resume macOS applications through the App Freezer native agent.

Overview

App Freezer for Raycast

Search, pause, and resume macOS applications from Raycast. This extension is a thin client: only the native App Freezer agent manages process trees, sends signals, applies safety rules, and persists recovery state.

Requirements

macOS
Raycast
App Freezer v0.1.0 or newer

The extension locates App Freezer by bundle identifier (com.chxsong.AppFreezer), invokes the bundled Contents/MacOS/appfreezerctl for typed JSON snapshots, and sends actions through the appfreezer:// URL scheme. It never sends process signals itself.

Install App Freezer before using the extension. The native app is distributed separately because process-tree management, safety exclusions, and recovery records remain in the signed macOS agent.
