Cinevva Engine
Build once, ship everywhere. An open-source game engine. Your games run in the browser, on mobile, and on desktop. Write your game once, then package it for any platform.

Build Your Own
Tell it what you're building in a sentence, and you'll work together from there. Nine specialist AI models handle 3D, animation, scenes, music, sound, visual effects, UI, game logic, and multiplayer, orchestrated through a typed runtime that compiles straight to a browser game. Chinese prompts work end to end.
Ship To Any Platform
- Mobile (iOS, Android) — via Capacitor, wraps your game in a native shell with access to device APIs
- Desktop (Windows, macOS, Linux) — via Tauri, lightweight native binaries under 10MB
- Steam — Tauri build, packaged with Steamworks SDK
- Discord Activities — runs inside Discord via their Embedded App SDK
- WeChat & Douyin Mini Games — export with a platform-specific adapter to reach China's mini-game ecosystem (see Cinevva for China)
- Web portals (CrazyGames, Poki, Newgrounds) — integrate their SDK for ads, leaderboards, and distribution
Same codebase. Different packaging. Ship mini games into China or Steam and web portals worldwide, all from one build.

Can I publish a browser game to Steam?
Yes. Your game builds to a desktop binary through Tauri and gets packaged with the Steamworks SDK, so the same project you tested in the browser is what ships on Steam. You don't rewrite anything for the desktop target.
Do Cinevva games run on iOS and Android?
Yes. Capacitor wraps the game in a native shell with access to device APIs, so one build reaches the App Store and Google Play alongside the web version. Mobile browsers play the web build directly without any install.
Do players need a plugin or a download?
No. Games run in the browser on WebGL and WebGPU, so a player opens a link and starts playing. Check what a given device supports with the free WebGL & WebGPU Checker.
Can I export a WeChat or Douyin mini game?
Yes. A platform-specific adapter exports your game into China's mini-game ecosystem, and you can build against those constraints from the start with WeChat mini game mode in the creator. See Cinevva for China for how that pipeline works.
