About

Hiro (formerly OmniWM) is a developer-signed and notarized tiling window manager for macOS inspired by Niri and Hyprland. Offers two layout engines: Niri-style scrollable vertical columns and Dwindle BSP. Includes a Ghostty-powered quake terminal, fuzzy command palette, and IPC/CLI automation. Requires macOS 26+.

Who It's For

Hiro is for macOS users on macOS 26 (Tahoe) who want a feature-rich tiling window manager with both niri-style scrollable columns and Dwindle BSP, packaged as a developer-signed and notarized app. Its distinguishing features include a Ghostty-powered quake terminal, a fuzzy command palette, and IPC/CLI automation — tools that complement tiling workflows but are typically separate utilities on other platforms. No SIP disabling is required.

How It Works

Hiro provides two layout engines switchable per-workspace: Niri-style scrollable vertical columns (windows arrange in columns that scroll horizontally) and Dwindle BSP (recursive binary splitting). The Ghostty-powered quake terminal drops down from the top of the screen with a hotkey — a persistent terminal that's always one key away without cluttering your layout. The unified command palette lets you fuzzy-search commands and windows from anywhere. Overview mode zooms out to show all windows in a Mission Control-style grid. App rules control automatic window placement and sizing. IPC/CLI automation lets external scripts and tools drive Hiro.

Compared to Similar Tools

Compared to Paneru (scrollable columns only, no SIP), Hiro adds Dwindle BSP, the Ghostty quake terminal, and IPC/CLI, but requires macOS 26 vs. Paneru's broader compatibility. Compared to AeroSpace (i3-style, broad macOS support), Hiro adds scrollable column layout and the built-in terminal/automation utilities. Compared to Nehir (a focused fork of Hiro built around scrollable columns only), Hiro retains multiple layout engines and the fuller feature set.
