Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 11, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 4% of issues opened in the past year have never received a reply. 100% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. 94% of issues opened in the past year have since been closed. Three people close 93% of everything that gets resolved.

Detailed Description

OmniWM is a tiling window manager for Apple Silicon Macs that combines scrolling container layouts with binary space partition tree algorithms.

The tool addresses the lack of native tiling window management on macOS by implementing a layout system that draws from two distinct approaches. It provides Niri-style scrolling containers, which organize windows in a continuous scrollable space, alongside Hyprland-style Dwindle BSP, a binary space partitioning algorithm that recursively divides screen space. This dual-layout approach lets users choose between fluid, scroll-based organization and traditional recursive splitting depending on their workflow.

Developers and power users on Apple Silicon Macs who want keyboard-driven window management without relying on external tools should consider this project. It suits those already familiar with tiling window managers on Linux who have switched to macOS and want similar functionality, as well as anyone seeking to maximize screen real estate through automated window arrangement. The tool is specifically built for Apple Silicon architecture, making it a native option rather than an emulated or compatibility-layer solution.

The project shows consistent development activity with regular commits addressing bug fixes and feature refinements. Work spans across core window management functionality, layout algorithms, and user interface improvements. The codebase receives ongoing maintenance with attention to stability and performance optimization for the target platform.
