JumpjetAlpha.

a wasm runtime for game developers.

Build your next game, engine or library with Jumpjet.
For any platform. In any language.

curl -fsSL https://jumpjet.dev/install.sh | bash iex (iwr -Uri "https://jumpjet.dev/install.ps1" -UseBasicParsing)

How does it work?

Until now, in order to build games for multiple platforms, developers had to write platform-specific code or rely on an engine to provide that support. And while libraries like SDL and raylib exist, they don't solve the toolchain problem.

Jumpjet bridges the gap between high-level game development and low-level hardware access, allowing developers to write code once and deploy it across multiple platforms.

Beyond just enabling multi-platform support, Jumpjet provides a host of APIs and tools that make it easy to build games.

use wit_bindgen::generate;

use crate::exports::jumpjet::runtime::client::Guest;
use crate::jumpjet::runtime::debug::log;

generate!({
    world: "game",
    path: ".jumpjet/wit",
    generate_all
});
export!(Game);

struct Game;

impl Guest for Game {
    fn init() -> Result<(), String> {
        log("init");
        Ok(())
    }

    fn update(time: f64, delta_time: f64) {
        log(&format!("update: {:?}", time));
    }

    fn render(time: f64, alpha: f64) {
        log(&format!("render: {:?}", time));
    }
}
import { log } from 'jumpjet:runtime/debug'

export const guest = {
  init() {
    log('init')
  },
  update(time, deltaTime) {
    log(`update ${time}`)
  },
  render(time, deltaTime) {
    log(`render ${time}`)
  }
}
Demo coming soon
