Replit Launches Agent 4 With Parallel Builds and Visual Design Canvas

· Updated

Replit launched Agent 4, a major new version of its AI app-building agent, with parallel task execution and a new visual design canvas. Agents now run independent tasks — authentication, database setup, frontend design — simultaneously, with progress visible throughout. A one-shot prompt generates a full requirements breakdown before the build begins. Agent 4 handles web apps, mobile apps, landing pages, pitch decks, and animated videos in the same project, with service integrations for Linear, Notion, and Excel.

This shifts Agent 4 from a single-task coding agent to a multi-role team builder. The task-based kanban workflow lets non-technical collaborators submit and track requests while agents execute in the background — the whole team participates, not just the developer.

Bring a one-shot prompt describing what you want built and let Agent 4 handle the sequencing, parallel execution, and design adjustments from there.
