Build games in your browser
Newly is a browser-based game engine. Create scenes, write gameplay in Luau or C#, 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 or C# 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.
