Replit launched Agent 4, its most powerful vibe coding agent to date. The release adds four core capabilities: a Design Canvas for exploring and tweaking UI visually before committing to code; a unified project workspace for producing web apps, mobile apps, pitch decks, and videos together; task-based team collaboration where the agent intelligently sequences and executes requests; and parallel execution where multiple agents tackle auth, database, and front-end work simultaneously. Agent 4 connects to services like Linear and Notion directly from chat.
The shift from Agent 3 is a deliberate philosophy change. Agent 3 maximized autonomy — running for hours uninterrupted. Agent 4 is designed to put human creativity back at the center, acting as an AI creative partner that handles background execution without interrupting the building process.
Describe your idea in plain language and Agent 4 builds it — no setup required, no coding background needed.
