⏰ Estimated time: 5 minutes · Follows from Build your first app You’ve built a web app. Now turn it into more — add a mobile app, a slide deck, or anything else, all inside the same project. Everything shares the same data and backend, so you don’t have to start over.

​
Before you begin

You’ll need an existing project on Replit — from a previous quickstart or any project you’ve created.

​
Your project can do more than one thing

When you built your first app, you created a web app. But a single project on Replit isn’t limited to one output. You can add a Mobile App that works on phones, a slide deck to present your idea, an animated video, and more — all living side by side in the same project. These are called artifacts. Each artifact is its own publishable output, but they all share the same code and data behind the scenes. Build once, publish everywhere.

​
Add a mobile app

1

Ask Agent to create a mobile version

Tell Agent what you want:
Add a mobile version of this app
You can also click the + button in the Preview panel to add a new artifact.
Agent builds a mobile app that shares the same backend as your web app — any data or logic you’ve already built carries over automatically.
2

Preview on a phone simulator

When Agent finishes, the Preview panel shows your mobile app running in a phone simulator. Tap around and test it just like you would on a real phone.
3

Switch between your apps

Use the dropdown in the Preview panel to switch between your web app and mobile app.
You can also ask Agent:
Show me the web app

​
Add even more to your project

Your project isn’t limited to web and mobile apps. You can ask Agent to create other types of artifacts too:
  • Slide decks — “Create a pitch deck for this app”
  • Animated videos — “Make a short explainer video for this app”
  • Data visualizations — “Build a dashboard showing usage stats”
  • Documents — “Write a one-pager describing this app”
Each one becomes a new artifact in your project, shareable with its own URL.

​
Publish your project

When you click Publish, all artifacts in your project go live together. Your web app, mobile app, and slide deck each get their own URL, and they stay connected through the same backend. Learn more in Publish your app.
