It creates pre-configured terminal layouts for your projects, so you can go from "I want to work on X" to a full development environment in one click. ## Configuration Place a `.lattices.json` file in your project root to define your workspace layout. lattices reads this file when creating a session. ## Menu Bar App The lattices menu bar app is a native macOS companion that lives in your menu bar and gives you quick access to all your lattices sessions. ## Workspace Layers & Tab Groups Two ways to organize related projects in `~/.lattices/workspace.json`: ## Daemon API The lattices menu bar app runs a WebSocket daemon on `ws://127.0.0.1:9399`. It exposes 20 RPC methods and 3 real-time events — everything the app can do, agents and scripts can do too. ## Overview lattices is a macOS developer workspace manager. It pairs terminal sessions with a native menu bar app to give you — and your AI coding agents — full control over terminal layouts, window tiling, and project navigation.
