free no code game engine
A free desktop game engine with optional no-code AI help
The local editor is free for 2D and 3D projects. No-code agent help comes from an external agent you use or from paid hosted Summer AI.
Summer Engine is a free desktop app for creating, editing, playing, and exporting local games. Your project stays in standard files on your machine.
The desktop app is proprietary software and its agent tools are MIT open source. You can work by hand or connect an external agent through the free local MCP link. Your external provider may charge.
If you choose hosted Summer AI to generate scenes, scripts, or assets from descriptions, you need an account and paid credits. Signup credits are not guaranteed.
What is free
Download the desktop app, create and edit a local project, play it, and export a build without paying Summer. The local MCP connection is free from Summer; an external agent may have its own cost.
What no-code help costs
Describe a change to an external agent connected over MCP or use hosted Summer AI. Hosted generation requires paid credits from the start. The free app alone does not include unlimited hosted AI generation.
A project you can keep
Summer Engine uses standard scenes and scripts compatible with Godot 4. You can open and edit the files directly whenever you want, whether you started manually or with agent help.
Create 2D and 3D games
The editor supports local 2D and 3D projects. You can play both without hosted AI credits. Agent-generated content follows the cost of the external agent or hosted Summer AI service you choose.
Export and sell
You own your local project and can export and sell it without Summer royalties. Store rules, signing, and target-platform testing still apply.
