ZIL — LCARS tiling window manager for macOS

ZIL is a tiling window manager for macOS 26 and later, built for large and ultrawide displays. Dynamic tiling — dwindle splits, a master-centre layout that puts your main work in the middle of a 32:9 desk, drag-to-resize bars, focus-follows-mouse — wrapped in a working, fan-made LCARS console. The frame around your windows is not decoration: it lists them, switches workspaces, and reads out live CPU, memory, Wi‑Fi, and SSD telemetry. Native Swift, Developer ID‑signed and notarized, and it runs with SIP on — Accessibility is the only permission it ever asks for.

• Dynamic dwindle BSP tiling, plus a master-centre layout built for ultrawide desks
• Nine workspaces per display with instant switching — layouts persist per workspace
• Named tile profiles, matched by app identity, so an arrangement survives relaunches and reboots
• Live sensors in the chrome itself — per-core CPU, memory pressure, Wi‑Fi signal, SSD free space
• Focus follows mouse, and it stands down while menus are open or you are dragging
• One hot-reloaded TOML file with per-machine profiles — the 49″ desk and the 13″ laptop share a config
• Native Swift, notarized, SIP stays on — Accessibility is the only permission

ZIL is live and free to download — Apple silicon, macOS 26 or later. Get it at zil.daystra.com, or get in touch about how we build with it.
