Summer Engine vs. Rosebud AI
Rosebud is for web prototypes. Summer is for shipping games to the world.
Rosebud AI
The Web Prototyper
- Run entirely in browser
- Instant shareable links
- Platform lock-in (web only)
- Limited engine depth
- Cannot export to Steam/Console
Summer Engine
The Full Engine
- Professional Game Engine
- Export to Steam, Console, Mobile, Web
- Full Source Code Access
- Vibe Code OR Write Code
- Offline Capable
The "Web Toy" Ceiling
Rosebud AI is an incredible tool for seeing an idea come to life instantly. If you want to make a quick prototype or a game jam entry to share with a link, it's fantastic.
But you will quickly hit a ceiling. Because it runs in the browser, you are limited in performance, complexity, and ownership. You can't easily build a large open world, use advanced compute shaders, or optimize for high-end hardware.
Summer Engine removes the ceiling. You start with the same ease of use (describing your game in English), but because it's a native desktop engine (built on Godot 4.6), you have unlimited headroom. You can build a 2D platformer today and a 3D MMO tomorrow.
Export to Everywhere
Rosebud is web-first and web-only. Your game lives on their site.
Summer lets you build for the world. You can export native binaries for Windows, macOS, and Linux. You can export to Android and iOS. You can even export to consoles (Switch, PS5, Xbox). And yes, you can also export to the Web.
Vibe Coding with Depth
Both engines let you "Vibe Code" (build without coding). But Summer allows you to graduate from Vibe Coding.
If you ever want to tweak a specific line of code, change a shader, or optimize a loop, Summer gives you full access to the source. You aren't trapped in a "no-code" prison. You have professional power when you need it, and AI ease when you don't.
Real Ownership
When you build on a proprietary web platform like Rosebud, you are renting your own game. If their servers go down, your game disappears.
Summer Engine respects your ownership. Your project files live on your computer. Your code is yours. You can use Git. You can backup to a hard drive. You are building an asset that you own forever.
