Download Summer Engine

Download for Your Platform

Get the latest Summer Engine installer from our website.

​
Alternative: Install via CLI

Cloud work needs nothing installed. Add https://mcp.summerengine.com/mcp to your agent and sign in once. Your agent can then make assets, work on plans, write the store page and publish. Engine work (scenes, scripts, play, screenshots) needs Summer Engine on your computer. If you use Cursor, Claude Code, or any MCP-compatible AI tool, you can install it from the command line:
This downloads and installs Summer Engine (macOS: /Applications/Summer.app; Windows: the installer-selected location). No global npm install is required. Then connect your agent, sign in and start the engine:
For each agent, see MCP Setup.
