Build games in your browser

Newly is a browser-based game engine. Create scenes, write gameplay in Luau, simulate real physics and publish to the web or Steam — with nothing to download and no setup.

What you can build

• Drag, snap and sculpt 3D scenes with a visual editor
• Script gameplay in Luau with live autocomplete
• Rapier rigid-body physics, simulated in real time
• Mobile-ready game UI, designed on a device frame
• Build together — live collaborative editing with your team
• Start from a template: platformer, first-person or blank

Who it's for

Hobbyists, students and indie teams who want to make a game today rather than spend a weekend installing an engine. Free to start, works on any computer with a modern browser.
