Topit

Topit is a macOS utility that lets users keep any application window positioned at the top of the screen. After launching the app, a user selects a window, and Topit pins it so it remains visible above other content, while still allowing the window to be moved, resized, or interacted with normally. The tool supports pinning multiple windows simultaneously.

The software requires macOS 13.0 or later and is distributed as open‑source, free‑tier software. Installation can be performed by downloading the latest release or via Homebrew. Topit relies on accessibility and screen‑recording permissions to capture and control windows, using the ScreenCapture Kit to minimize CPU load, though extensive pinning may increase battery usage.

Topit is intended for users who need persistent visibility of certain windows—such as reference material, monitoring tools, or chat panels—while working with other applications. Its design focuses on straightforward window management without additional features beyond the pinning capability.
