Replit introduced Agent 3, an upgrade to its AI coding agent that can periodically test apps in a browser and automatically fix issues. The agent is claimed to be 10x more autonomous, 3x faster, and 10x more cost-effective than Computer Use models. Agent 3 can also generate other agents and automations, and run autonomously for up to 200 minutes. The new app creation flow offers both full-stack and frontend-only modes.
