Replit is a browser-based integrated development environment (IDE) that combines AI-powered code generation with instant deployment. Its Agent 2.0 feature can build full-stack applications from natural language descriptions, handling everything from project scaffolding to database setup and hosting.

Replit supports 50+ programming languages out of the box with zero configuration. Developers can write, test, and deploy applications entirely in the browser without managing servers or infrastructure. The AI assistant provides inline code suggestions, debugging help, and can generate entire features based on prompts.

Key capabilities include real-time collaboration (multiplayer editing), built-in package management, a Ghostwriter AI assistant, one-click deployment with automatic HTTPS/SSL, and integrated database support. Replit is used by everyone from beginners learning to code to professional developers prototyping and shipping applications.
