Agent 3 from Replit is an advanced AI agent designed to generate full-stack web apps based on natural language input. It autonomously builds, tests (via a browser), fixes detected issues, and can run for up to ~200 minutes with minimal supervision. It also supports building sub-agents/automations (e.g. Slack bots, Telegram bots), integrations with services (Notion, APIs, etc.), rapid prototyping and frontend/backend workflows.
