# HTML5 game maker guide, and where Summer stands today

> Describe the game you want and Summer Engine builds it as a real project on your desktop. A GDScript project also exports a web build, so here is what an HTML5 build needs and how Summer ships one.

An HTML5 game needs a WebGL build playable from a link with no plugin or install, a canvas that resizes to any screen, and input that works with keyboard, mouse, and touch, on desktop and mobile browsers alike. Summer exports a web build for a GDScript project, and you publish it on Summer Games, where people play it in the browser.

Everything is a standard project, because Summer Engine is a full engine compatible with Godot 4. That gives you a web build for Summer Games, or a Windows or macOS build you can publish on Steam, itch.io, or your own domain, keeping the whole project on your machine with no lock-in.

You keep iterating in plain language. Adjust the controls, the layout, the difficulty, or the art, and see each change in the running game on your desktop before you export a build.

## What an HTML5 build has to handle

An HTML5 game lives inside a page, so the canvas has to resize to any window, the assets have to be compressed so the first frame arrives fast on a phone connection, and the controls have to accept keyboard, mouse, and touch. With Godot 4.3 and later, a single-threaded web export runs without special server headers, while threaded builds need COOP and COEP headers from the host. Summer Engine builds and tests games on the desktop, so check these web constraints in the web build you export.

## It makes the art and audio too

Ask for the look and sound you want and the maker generates the assets and imports them as standard resources in your project. You can recolor, swap, or replace anything by asking, or open it in the editor, so the game looks the way you pictured without sourcing art first.

## Where HTML5 games get published, and the Summer path

itch.io is the most common home for HTML5 games, and it caps an upload at 500 MB in total, 200 MB per file, and 1,000 files, so size budgets matter from day one. When your game plays the way you want in Summer Engine, export a web build of a GDScript project and publish it on Summer Games, or export a Windows or macOS build and publish it on itch.io as a download, on Steam, or on your own domain, and you own every file with no royalties and no revenue share.

## No code, all conversation

You build and refine the entire game in plain language. Change input, tune difficulty, add a level, restyle a sprite, all by asking. If you want to go deeper, the project uses standard scripts and scenes you can edit directly.

## FAQ

### Can I make a game without coding in Summer?

Yes. You describe the game in plain English and Summer Engine builds it on the desktop, with scenes, scripts, and assets in one standard project. No programming is required, though you can edit the project directly if you want to. The output is a Windows or macOS build, and a GDScript project also exports a web build.

### Can Summer export HTML5 or WebGL?

Yes, for a GDScript project. Summer exports a web build, a standard static .zip with index.html at the root, and you publish it on Summer Games. Summer's own web template uses WebGPU, and Summer Games also accepts Godot's standard Web export with the Compatibility renderer. C# projects cannot export to the web.

### What does an HTML5 game need that a desktop game does not?

A canvas that scales to any window, compressed assets so it loads on a phone connection, and input that handles keyboard, mouse, and touch together. Threaded web builds also need COOP and COEP headers from the host, while Godot 4.3 and later single-threaded builds do not. These are the checks to run on any web build, including one you export from Summer.

### Does it make the assets?

Yes. It can generate the art and audio your game needs and import them as standard resources in the project. Anything generated can be swapped or restyled by asking.

### Is it free to start?

Summer Engine is free to download and free to start, and the core engine is open source, so you can build and play a game at no cost. You only pay for heavier AI usage as your project scales.
