Product: niri is a scrollable-tiling Wayland compositor.
Window layout: Windows are arranged in columns on an infinite strip, and opening a window does not resize existing windows.
Workspaces: Workspaces are dynamic and arranged vertically, with an independent set for each monitor.
Features: Features include an overview, built-in screenshot UI, window tabs, touchpad and mouse gestures, configurable layouts, animations, and live-reloading configuration.
Screencasting: Niri supports monitor and window screencasting through portals and PipeWire, and can block selected windows from casts.
Integrations: Niri integrates with xwayland-satellite to run X11 applications, spawning it on demand when an X11 client connects.
Desktop shells: The project lists DankMaterialShell and Noctalia as desktop shells that support niri, and says niri itself is not a complete desktop environment.
Accessibility: The project says niri works with screen readers.
Security: The security guide says untrusted clients need a sandbox that removes niri's IPC socket, blocks host D-Bus access, and uses a filtered Wayland socket; it names Flatpak as one suitable sandbox.
License: The GitHub repository identifies the project license as GPL-3.0.
Stability: The project describes niri as stable for day-to-day use and says it does most things expected of a Wayland compositor.
Support: The project identifies its Matrix chat as the main communication channel for questions and also links a community Discord server.
Notable limitation: The project says niri supports touchscreens but does not yet support touchscreen gestures.
Installation: The getting-started guide lists distribution packages and building from source as installation options.
