Publishing lets you share your Replit App with the world using a simplified process.

​
What is Publishing?

Publishing is a feature that saves a snapshot of your Replit App to the cloud, where everyone can interact with it. A snapshot captures the current state of the files in your Replit App. When you publish your Replit App, you create a published app. A published app is a running instance of your app on Replit’s cloud infrastructure. This makes the app reliably available on the internet, separate from the version in your workspace.
Replit’s infrastructure is backed by Google Cloud Platform (GCP). All published apps are hosted in the United States.
Publishing includes tools to monitor your published app status and view web analytics. Replit offers the following deployment types:

Autoscale Deployment

Automatically adjusts resources based on your app’s usage.

Static Deployment

Provides an affordable way to host websites that don’t change based on user input.

Reserved VM Deployment

Provides a consistent amount of computing resources for your app to run continuously.

Scheduled Deployment

Runs your app at scheduled times that you choose.

Key features

Publishing offers the following convenient features:
  • Multiple publishing options: Select or update a deployment type that meets your needs in a few clicks.
  • Custom domains: Serve your app from your web domain.
  • Analytics: Track visitor data and other metrics for your published app.
  • Monitoring tools: View your published app status and configuration.
  • Access controls: Control who can see your app with a single click. Available only for Teams members.

​
How it works

When you publish your Replit App, Replit creates a snapshot of your app’s files and dependencies. This snapshot is then sent to Replit’s cloud infrastructure, where it runs as a separate instance of your app. To update your published app with the latest changes, publish again to create a fresh snapshot.
Avoid saving and relying on data written to a published app’s filesystem. To store data, use a storage or database option such as Replit’s Storage and Database offerings.

​
Use cases

The following examples show different types of published apps.

​
Autoscale deployment: Typing speed assessment app

Let the cloud scale up resources when users take typing tests and reduce them when not in use.

​
Static deployment: Solar system simulation

Learn about the planets in a solar system visualization app on the web. This visualization renders in the browser and doesn’t transfer any user input to a server.

​
Reserved VM deployment: Discord bot

Run a Discord bot that helps you moderate and onboard members. It’s always online to chat with users and respond to commands with predictable pricing and performance.

​
Scheduled deployment: Home automation triggers

Schedule API calls to start and stop your smart home devices at specific times and days.
