Replit

Browser-based IDE with AI agent, hosting, and collaborative coding environments.

Overview

Replit is a cloud-based development platform that combines AI-assisted coding with a full-stack infrastructure for building applications. The platform features Agent 4, an AI assistant that can turn natural language prompts into functional prototypes, handle parallel task execution, and support real-time team collaboration. It provides built-in services for authentication, databases, hosting, and monitoring, along with integrations to 100+ external services.

The platform supports multiple project types including web apps, mobile apps, landing pages, design systems, slides, animations, and data visualizations. Teams can work together with parallel agent execution, task management via kanban boards, and role-based access controls. Replit handles deployment and scaling automatically, allowing developers to focus on building rather than infrastructure.
