Overview
Replit is an online IDE and app generation platform that runs in the browser. After launching Replit Agent in 2024, it updated to Agent 4 in 2026 — the fastest, most versatile Agent yet. Generates full-stack apps (frontend, backend, DB, deployment) from natural language. Mobile development (React Native + Expo) support arrived in early 2026.
