Platforms

Pick the platform, not the framework.

Where your app runs is a platform. Each one is a package you add with one command, and they all share the same app/ folder, the same packages and the same CLI.

Platform	Targets	Built with	Add it
Web	Static, SPA, SSR, PWA	Vite + TanStack Start	`kitr add web site --mode ssr`
Server	Node, Bun, Deno, Workers	h3	`kitr add server api --runtime node`
DesktopComing soon	Windows, macOS, Linux	Electron	`kitr add desktop app`
TauriComing soon	Windows, macOS, Linux	Rust + system webview	`kitr add tauri app`
MobileComing soon	iOS, Android	Capacitor	`kitr add mobile phone`

Need something else, like a kiosk or a browser extension? A platform is a package with a definePlatform() factory, so you can write your own. Write a platform →

Mix and match

One app. As many platforms as you need.

A platform is one named line in kitrrc.ts. Add one with a single command, keep several of the same type, and run them all with kitr dev. They share your app/ folder, your data contracts and your packages.

Electron or Tauri: a project keeps one desktop shell.

// kitrrc.ts
import { defineKitrConfig } from 'kitr/app'
import { server } from 'kitr/server'
import { web } from 'kitr/web'

export default defineKitrConfig({
  platforms: {
    site: web({ mode: 'ssr' }),
    api: server({ runtime: 'node' }),
  },
})

$ kitr add web site --mode ssr

$ kitr add server api

$ kitr dev

✓ site http://localhost:3000

✓ api http://localhost:3001
