## What it is
The Mirror is an open-source, all-in-one multiplayer game development platform whose V1 (Mirror Classic) is built on Godot, combining a networked real-time editor, visual scripting, in-world GDScript editing, Jolt physics, and cloud or self-hosted asset management. The project is transitioning to V2, a new TypeScript-based Mirror Engine currently in alpha, while Mirror Classic remains MIT-licensed in this repository.

## Use cases
- build multiplayer games without writing code
- collaboratively create virtual worlds with friends in real time
- open-source alternative to roblox studio or uefn
- visual scripting engine for non-programmers
- live-edit game code and materials while the game is running
- self-hosted game creation platform with cloud asset management

## When to choose
- You want a Godot-based, no-code/visual-scripting environment for building multiplayer games, digital experiences, or virtual worlds
- You need a real-time collaborative editor where multiple people can build and play in the same world simultaneously
- You want an open-source, MIT-licensed Roblox/UEFN-style editor-and-game combination you can self-host

## When to avoid
- You need a stable, long-term-supported engine today - the project is mid-transition from Godot to a new TypeScript engine (V2) that is still in alpha
- You require deep low-level engine customization or a mature production pipeline rather than an all-in-one editor app
- You need guaranteed open-source access to the newest version - V2 is planned as open-core with alpha access gated through Discord
