Web apps are the default output type on Replit. When you describe an idea to Agent, it builds a full-stack web application unless you specify a different artifact type.

​
Getting started

There are two ways to create a web app:
  • Type a prompt: Describe what you want to build on the Replit homepage. Agent automatically creates a web app.
  • Select from the dropdown: Open the app type dropdown on the homepage and choose Web app, then describe your idea.

​
Key features

  • Full-stack by default: Every web app includes a frontend and backend. Agent sets up API routes, a database, and server-side logic as your app needs them.
  • Responsive design: Apps adapt to different screen sizes automatically.
  • Instant deploy: Publish your app with one click. Replit handles hosting, SSL, and infrastructure.
  • Shared infrastructure: If your project has multiple artifacts — like a mobile app or data dashboard — they all share the same backend, database, and services.

​
Use cases

  • SaaS products: Build customer-facing tools, dashboards, and platforms.
  • Internal tools: Create admin panels, CRMs, or workflow apps for your team.
  • Landing pages: Launch marketing sites with forms, animations, and dynamic content.
  • Marketplaces and directories: Build listing sites, job boards, or community platforms.
