Deploying

Kazzle apps can be deployed to Kazzle’s hosting or installed on device computers.

​
Remote deploy

Deploys are asynchronous: the app page, the AI, or kazzle deploy from a checkout queues a server-side deploy job. kazzle deploy uploads your checkout; the deploy runner builds and ships it. For each component:
  1. UI components are built into a Docker image that runs runtime.prod.build when set, otherwise bun run build
  2. Process components run their runtime.prod.command command from kazzle.config.ts - deploy fails if it’s missing
  3. Each component gets its own image and deployment
  4. A production URL is assigned
Trigger a deploy from the app page or via the AI:

​
Production URLs

Deployed apps get a URL like https://kazzle-{appId}.kazzle.app. Apps with multiple process components get one URL per component. Public apps are accessible to anyone with the URL. Private apps require Kazzle authentication.

​
Runtime commands in production

Production commands must be bare commands (e.g. bun server/index.ts) - the deployed runtime injects PORT, HOST, and secrets directly. See the Kazzle CLI page for the dev/production split.

​
Local install

Apps can also run on device computers (your local machine) via the Kazzle daemon. The runtime.dev.command command starts the app in development mode.
