+# Desktop App
+
+AgentKernel includes a native macOS desktop app built with [Tauri 2](https://tauri.app/). It provides a GUI for managing sandboxes, snapshots, templates, and agents — all backed by the same HTTP API as the CLI.

+
+## Requirements
+
+- macOS 26+ (Apple Containers) or macOS with Docker Desktop
+- The `agentkernel` server running (`agentkernel serve` or `make serve`)
+
+## Install
+
+Download the latest `.app` bundle from [GitHub Releases](https://github.com/thrashr888/agentkernel/releases), or build from source.
+
+## Build from Source
+
+```bash
+# Install dependencies
+cd app && npm ci
+
+# Run in development mode (hot-reload)
+make app
+
+# Build release .app bundle
+cd app && npx tauri build
+```
+
+The built `.app` bundle is output to `app/src-tauri/target/release/bundle/macos/`.
+
+## Features
+
+| Page | Description |
+|------|-------------|
+| Dashboard | Server health, sandbox count, quick actions |
+| Sandboxes | Create, start, stop, delete sandboxes with terminal access |
+| Sandbox Detail | Exec commands, file browser, live logs |
+| Snapshots | Save and restore sandbox state |
+| Templates | Quick-launch from predefined configurations |
+| Agents | View and install supported AI agent CLIs |
+| Policy | View and manage sandbox security policies |
+| Secrets | Manage environment secrets passed to sandboxes |
+| Audit Log | View sandbox lifecycle events |
+| Diagnostics | System health checks and backend status |
+| Settings | Configure server URL and preferences |
+
+## Architecture
+
+```
+app/
+├── src/                 # React 19 + TypeScript frontend
+│   ├── pages/           # Route pages (Dashboard, Sandboxes, etc.)
+│   ├── components/      # Shared UI components (shadcn/ui)
+│   └── lib/             # API client, hooks, types
+└── src-tauri/           # Rust backend (Tauri 2)
+    ├── src/commands/    # Tauri IPC commands
+    ├── src/api_client.rs # HTTP client to agentkernel server
+    └── src/types.rs     # Shared type definitions
+```
+
+The desktop app communicates with the `agentkernel serve` HTTP API. The Tauri backend acts as a bridge, forwarding IPC calls from the frontend to the server.
