Replit is a browser-based coding platform and IDE used by 30 million+ developers and students worldwide. It eliminates the biggest friction point in software development — environment setup — by providing a complete development environment, runtime and hosting infrastructure that works entirely in your browser. You open a new project and start coding immediately, in any of 50+ programming languages, without installing anything.
Replit AI is the platform's integrated AI coding assistant that writes code from natural language descriptions, autocompletes functions, explains what existing code does, suggests fixes for errors and answers programming questions in context. Unlike GitHub Copilot which only assists in dedicated code editors, Replit AI is embedded in a complete development environment — so when the AI writes code, you can run and test it immediately in the same window.
For beginners and students, Replit removes every barrier to getting started with programming. For professional developers, it's the fastest way to prototype ideas, collaborate in real time with other developers (multiplayer coding works like Google Docs), or deploy a quick proof of concept without configuring cloud infrastructure. Replit handles deployment automatically — when you're ready, your project is live with one click.
