The AI era belongs to creators.
Yes, that's you.
Playing great games makes you smarter. Making them makes you even smarter.
How your game gets there.
Runs your Scratch projects — as they are
Export your project, hit compile, done. The Yu Compiler — an engine rebuilt from the ground up in Rust — takes the .sb3 you already have and turns it into a real console game. No rewrites, no ports, no "almost works": full Scratch compatibility is the floor, and everything that ran in your browser runs in your hands.
Boots in milliseconds, runs on almost nothing
Your project is compiled ahead of time into compact bytecode, so a whole game ships as a single file measured in megabytes — not a browser bundle measured in hundreds.* It boots in milliseconds, runs in a fraction of the memory, and sips battery. Press power, and you're playing.
One project, six targets
The same compile also ships your game to desktop, the web, Android, iOS — even microcontrollers that cost a couple of dollars.* Your work is never trapped on one device; MoDeck is simply its favorite home.
* Placeholder figures — file-size & cost estimates pending final product confirmation.
Your audience, built in.
One-tap publish, no gatekeepers
Finish your game, tap publish, and it's live in the community library — on every MoDeck in the world, the same minute. No app store, no review queue, no fees. Shipping a game feels exactly as easy as saving one.
Fans you can count
Play counts, comments, and follows live right next to your game. You see which levels people love, where they give up, and who's coming back — a real audience, growing game by game.
The remix chain
Every game on MoDeck is open to remix, and every remix credits the games it grew from. When a kid in another country bends your idea into something new, your name travels with it.
An open platform, not a walled garden
A share link runs your game in a browser or on a phone*, so grandparents and classmates don't need a console to play it. And MoDeck plugs into the world's largest kid-coding communities — ideas flow in, your work flows out.

Powered by the Yu Compiler.
Meet the Yu Compiler
MoDeck doesn't patch the old Scratch runtime — it replaces it. The Yu Compiler, a ground-up rewrite in Rust, compiles kids' blocks ahead of time into its own compact bytecode — with a custom JIT for the hottest code paths and a GPU-instanced renderer fed by assets prepared entirely at compile time.
Less overhead means less power — cooler hands, longer battery.
The payoff: the same game runs smoother — or the same handheld runs far bigger worlds.
In compute-heavy scenes, kids' creations run far beyond what the official Scratch engine can reach.* And when every engine hits the rendering wall, MoDeck's edge is different in kind — it keeps running on hardware a browser can't even boot on.
* Placeholder figures — benchmark multiples pending audited data.
Seeing is believing.
The same community game, captured side by side — in the Scratch web player, in TurboWarp, and on MoDeck hardware.

Why is MoDeck this fast? ▾
How it stacks up.
| SPEC | MODECK ENGINE | TURBOWARP | SCRATCH |
|---|---|---|---|
| Core architecture | Yu Compiler — ground-up rewrite in Rust | Fork of the Scratch VM (JavaScript) | Scratch VM (JavaScript) |
| Execution | AOT-compiled to compact bytecode, custom JIT on hot paths | Blocks compile to JS, then the browser's JIT | Interpreted, block by block |
| Rendering & assets | GPU-instanced drawing; atlases, collision & audio pre-baked at compile time | WebGL drawing; game logic on the CPU | WebGL drawing; game logic on the CPU |
| Speed — compute-heavy* | ~100x | ~10x | 1x |
| Startup & footprint* | Boots in milliseconds; a whole game ships as one file, a few MB | Browser-grade; packaged apps bundle a whole browser (100 MB+) | Browser-grade |
| Power draw* | Low — designed for handheld battery | Browser-grade | Browser-grade |
| In practice | Bigger worlds, more sprites, steady frame rates — in your hands | Faster, in a desktop browser | Great for first projects |
Runs everything Scratch runs.
Then keeps going.
Full Scratch compatibility is the floor, not the ceiling. The engine adds powers the Scratch world has never had:
Plugins, by everyone
A plugin system stacked with built-ins — camera control and more — and open to community contributions. Scratch's base powers, growing every week.
Truly online
Real networked services, running live — multiplayer ships in the box. Kids build MMO-style games and co-op storybooks their friends join in real time.
Motion play
The console's hardware is theirs to program: gyroscope, rumble, and more. Tilt to steer, shake to stir — games you play with your whole body.
Why is MoDeck this powerful? ▾
Built different, on purpose.
Compiled, not interpreted
Scratch is interpreted JavaScript; TurboWarp compiles it to JS but still lives inside a browser engine. The Yu Compiler — built from scratch in Rust — compiles projects ahead of time into its own compact bytecode, run by a lightweight VM with zero-allocation hot paths. Lighter and faster to run — and safer, because compiled games are far harder to crack or copy.
The compiler does the heavy lifting
Texture atlases, collision masks, audio transcoding, GPU-ready assets — all baked at compile time, so at play time the engine just runs. And the same pipeline is 3D-ready: real 3D assets and modern shaders have a home here that block runtimes can't offer.
Light enough for a $50 handheld
Games boot in milliseconds instead of seconds, run in a fraction of the memory, and ship as a single file measured in megabytes — not hundreds of them.* That's why MoDeck runs buttery-smooth on hardware a browser can't even boot on.
AI-ready by design
AI isn't bolted on — the Yu Compiler gives it a native interface: structured patches, preview gates that verify every AI edit before it lands, and self-repair diagnostics AI can act on. Bring Claude, ChatGPT, or any AI workflow — an idea becomes a running game, fast.
* Placeholder figures — footprint & cost estimates pending final hardware.
Three ways in.
Tell the AI
Describe the game in your head, and the AI builds it with you, step by step. Every AI edit is checked and previewed before it lands, so your project never silently breaks — and you can bring Claude, ChatGPT, or any AI you like. Never written a line of code? That's fine. Neither has your imagination.
Remix anything
Every game on MoDeck is an invitation: open it up, see how it works, and bend it into something new. Starting from a game you love beats staring at a blank page — and it's how most creators here make their first game.
Blocks & Python, when you're ready
When you want to go deeper, Scratch blocks and Python are right there — on the same project, in the same studio. Grow from "tell the AI" to "I'll write this part myself" without ever switching worlds.
CREATOR STORY — coming with our first cohort of kid creators.
Where it takes you.
Game jams with friends
A team, a weekend, one wild idea — and by Sunday night there's a finished game in your hands and a crowd taking turns with it. Jams are where "someday I'll make a game" becomes "we made one."
Maker fairs & competitions
What you build on MoDeck doesn't stay on MoDeck. Take your projects to maker fairs and enter them in coding competitions* — a real, running game on real hardware stands out in any lineup of posters and slideshows.
The featured shelf & your portfolio
The best community games get featured on the front shelf of every MoDeck on Earth — your name, in every player's hands. Game by game, that becomes a portfolio: proof of what you can imagine, build, and ship.
