Miracle – A hackable window manager for Linux (github.com)

Miracle (miracle-wm) is an open-source, hackable Wayland window manager for Linux built on Mir, designed to bring i3/Sway-style keyboard tiling with added animations and extensibility. It includes manual tiling and mixed floating/tiled workspaces, supports multi-monitor independent workspaces, and offers i3/Sway-compatible IPC. A key feature is a sandboxed WebAssembly plugin system (with a Rust plugin crate) that lets users extend placement, input handling, animations, and configuration behavior without modifying the compositor core.
