# Publish your app
> Make your app available to the world — understand the difference between building and publishing.
⏰ *Estimated time: 2 minutes* · Follows from [Build your first app](/getting-started/quickstarts/ask-ai)
Up until now, your apps work in the Project Editor. But right now, only you can see them. Publishing makes them available to everyone.
## Building vs. publishing
While you're working with Agent, your app runs in a **private building environment**. You can see it in the Preview tab, test it, and make changes, but no one else can access it. Think of it like a draft: it exists, but it's not shared yet.
When you **publish**, Replit takes your app and puts it on the internet with its own public URL. Now anyone with the link can visit it on any device, anywhere in the world.
## Publish your app
In the Project Editor, click the **Publish** button.
That's it. Replit packages your app, hosts it on its servers, and gives it a public `.replit.app` URL. Copy it and share it anywhere.
If your project has multiple artifacts — like a web app, a mobile app, and a slide deck — they all go live together when you publish. Each one gets its own URL.
## Updating your app
Every time you make changes and click **Publish** again, your app updates at the same URL. Visitors will see the latest version immediately. No need to share a new link.
## Next steps
Use your own domain instead of .replit.app.
