# Newly

> Newly (newly.gg) is a free, browser-based 3D and 2D game engine and game platform. Creators build worlds in a visual editor, script gameplay in Luau (the typed Lua used on Roblox) or C#, add physics and multiplayer, and publish with one click to a shareable link. Players open those worlds instantly in any modern browser, with nothing to download.

Newly is in early access. Building, publishing and playing are free; Newly Pro is an optional upgrade.

## What it is

- A Roblox Studio-style editor that runs in a browser tab: drag, snap and sculpt 3D scenes, paint terrain, change the sky.
- Scripting in more than one language, with live autocomplete:
  - Luau: the main language, for 3D and 2D games. Anyone who has scripted on Roblox will feel at home.
  - C# (early access): for 2D games, compiled in the browser by the real C# compiler. Familiar from Unity.
  - C++: coming soon.
- Real-time rigid-body physics (Rapier) and multiplayer worlds.
- Live co-editing: invite friends into the editor and build the same world together.
- Templates (a farm, a town, an empty baseplate) so beginners can make something playable without writing code.
- One-click publishing: every world gets its own page at newly.gg/game/<name>, a share link and an embed code. Games can also be packaged for Steam.
- In-world stores with items players can buy, plus an asset store for creators.
- A player side: browse and play community-made 3D worlds, like and pin favourites, add friends and join the same world.

## Who it's for

- Kids, teens and hobbyists who want to make Roblox-style games without installing anything (anyone can sign up; for players under 13, chat, voice and friend requests stay off until a parent turns them on).
- Students and teachers looking for a free game maker that works on school laptops and Chromebooks.
- Indie developers who want a lightweight web-first 3D engine with multiplayer built in.
