Replit: build and deploy applications right from your browser
Discover Replit, the AI-powered online development environment
Replit is an online development environment that lets you code, run and deploy applications directly from the browser, with nothing to install.
An internal tracking tool, a prototype to show a client, a small API to connect two services: with Replit, Monday morning's idea can be live by Monday evening. And with Replit Agent, a plain-language description is enough to generate a first working version of the application.
Replit is built around four pillars:
From writing code to going live, everything happens in one place.
1. The online IDE: code with zero setup
A full environment available from any browser, ready in seconds.
- Start a project in all major languages without configuring your machine
- Run and test your code directly in the browser
- Install dependencies and manage secrets inside the environment
- Pick up your work from any device, everything lives in the cloud
2. Replit Agent: from description to application
Replit's AI assistant turns a need expressed in natural language into a working application.
- Describe the application you want and let the agent generate a first version
- Iterate through conversation: ask for fixes and improvements
- Keep full control of the generated code to fine-tune it
- Save days on the prototyping phase of an internal tool
3. Real-time collaboration
Replit works as a team sport, like a shared document.
- Code together on the same project, simultaneously
- Share a link so anyone can test your application immediately
- Comment on and review code directly in the environment
- Support learning: the tool is widely used for coding education
4. Built-in deployment: from idea to production
No need for a second tool to go live: hosting is part of the platform.
- Deploy your application in a few clicks from the editor
- Host websites, APIs and applications on Replit's infrastructure
- Connect a database without leaving the platform
- Move from prototype to first real usage without a migration
What about going further?
Replit shines for prototyping and internal tools. For more structured business applications, it compares with platforms such as Bubble, Xano or Lovable, each with its own sweet spot. Browse our app builder category to compare.
