Replit is an online IDE and AI programming platform that supports browsers and mobile terminals. Its core products include Ghostwriter AI assisted programming assistant and Agent platform. Ghostwriter can provide intelligent code completion, explanation, Bug debugging and multilingual support, suitable for newcomers and professional developers to write code efficiently. Agent v2, launched in 2025, supports the use of natural language to describe requirements, automatically generates the entire software application (including front-end, back-end, architecture settings, deployment, etc.), and has project preview and feedback optimization capabilities. Replit aims to promote the concept of "vibe coding": direct prototyping of products through AI interaction, significantly lowering the development barrier. Tens of millions of users have experienced it, but environmental security incidents have also occurred, and Replit is strengthening its isolation mechanism and disaster recovery strategy.
