Teams already building on Replit get parallel agents and a design canvas, but it sits behind paid plans that run up to $100 a month.

Kenning's take

What it does

Agent 4 is the version of Replit's AI agent released in March 2026. It runs several agents in parallel on separate tasks such as auth, database and front end, then merges the work into the main app, and adds an infinite canvas for trying design variants before applying them. It can also make mobile apps, landing pages, slide decks and videos in the same project, and is part of Replit's paid plans.

• Parallel agents working on separate tasks
• Infinite canvas for design variants
• Visual edits applied straight to code
• Web, mobile, decks and videos in one project
• Requests sequenced automatically for teams

Who it suits. People and teams building apps on Replit who want design and code work to run side by side.
