Build browser-ready 3D games without a game engine's learning curve. Combine game controls, physics, collisions, and visual logic to design playable experiences, then publish them to the web where anyone can jump in instantly.
Get started — it's freePlayable experiences drive deeper engagement than any static content.
Studios and indie creators use Spline to prototype and ship web games with real-time physics, characters, and game logic - all designed visually.
How 3D games go from concept to playable release
Spline simplifies the entire pipeline for making 3D games from the first graybox level to polished, playable builds on the web.
Ideate
Block out levels and mechanics fast with parametric shapes, community assets, and physics. Test movement immediately with built-in first- and third-person game controls, and iterate on the core loop before investing in art.
Design
Build out the experience: model and texture your world, animate characters, and wire up gameplay with events like collisions, trigger areas, and key presses. Use variables for score and health, conditional logic for rules, and sound actions for feedback.
Ship to Production
Publish your game as a web experience or embed it anywhere - no installs, no app stores. Players get instant, cross-device access, and you can update the live game as often as you like.
Remix Playable Games from the Community
Discover game templates and mechanics to jumpstart your playable 3D projects.
