Replit's fourth-generation autonomous coding agent. Parallel sub-agents (auth, DB, backend, frontend simultaneously), mobile app generation, infinite canvas design variants. ChatGPT distribution partnership. 2.28M monthly visits (SimilarWeb). Best for non-developer / vibe-coding audience building full-stack apps.

Editorial verdict
Architecturally impressive and the ChatGPT integration could make it the dominant tool for non-developers building apps. For professional software factories (issue → PR, CI integration, repository-scale refactors), it falls short of the top tier. Production deletion incident (CEO apologized) is a trust signal issue.

Public evidence
Agent 4 introduces parallel sub-agents running auth, DB, backend, and frontend tasks simultaneously. Mobile app generation and infinite canvas for design variants are genuinely new capabilities.
A Replit AI agent autonomously deleted a company's codebase. CEO apologized publicly. This is a documented production safety incident that mirrors the Kiro pattern.
