Freedom to Own

The Mirror is the open-source Roblox & UEFN alternative
built on Godot and NestJS, allowing you to own everything
- unlike Roblox, Unreal/Fortnite, and Unity.

(Real) Real-Time Game Development

Everything in The Mirror is in real time, similar to live collaboration with Figma and Google docs.

No waiting for long build times: See changes instantly with friends and colleagues.

Check out our recent co-building session with Code With Tom!

All-in-One Game Development

The Mirror provides everything you need out-of-the-box without writing a single line of code.

The Editor &
The Game, Combined

Creates like an engine, plays like a game: The most fun way to build.

All-in-one: One app to build & play
Real-time everything: The most fun and easiest way to build
Instant game previews: No waiting for long build times
Integrated asset marketplace
First-person, third-person, & VR player controllers
3D pains done for you out-of-the-box
Launch your game in The Mirror or on third-party stores like Steam

Built on Godot

Our long-term aim is for bidirectionality with Godot: Start in The Mirror and end in Godot, or start in Godot and end in The Mirror.

Analogy: If Godot is Photoshop, The Mirror is Canva
GDScript in-world in real-time
Real-time shader editing (future)
No-code visual scripting
Import valid nodes from Godot
Godot plugin for real-time editing (future)
The Mirror contributes back to Godot

Out-of-the Box Everything

Real-Time Co-Building

Iterate on your game's features quickly by building in real-time with your users, friends, and colleagues. What you see is what you get.

Multiplayer by Default

Multiplayer networking is hard: The Mirror gives you no-code networking out-of-the-box.

Physics Sandbox

Control everything from gravity, collisions, and physics, joints, ragdolls, and destruction, automatically networked.
*Some physics features are a work in progress.

All Skill Levels

New to coding? No problem! The Mirror is designed for no-code, low-code, and experienced developers. Anyone can build with ease.

Import from Godot & 3D Modeling Tools

Import from Godot (GLB), Blender, or any other tool you wish to build the world of your dreams.

Monetize on the Marketplace

Sell your 3D models, scripts, and and even Godot components. Monetize anything without needing to create a full game.

Coming Soon: Marketplace

Easily monetize assets, from 3D models to audio to scripts and more.

Experience Assets

Driving a car is better than seeing a car: Incorporate assets into Mirror Spaces for players to experience.


Any asset made in a Mirror Space can be ported to any other Space. Any Godot GLB export will bring in valid nodes. Long-term, we plan for bidirectionality with Godot.

Showcase Your Work

Build an audience and reach new builders, artists, and game developers.
