Multiplayer design
for you and your agents.

CodeKit is a multiplayer design harness for product teams and their agents to design, plan, and build together – all from your codebase.The design harness for product teams and their agents to design, plan, and build together – all from your codebase.

Agents think in one line.
Good design doesn't.

A chat goes one message at a time. Design needs room: directions side by side, a team pointing at them, and agents drawing the next version from your own code. CodeKit gives them a canvas.

NEW

A canvas your agent draws on

Ask for three directions and watch them fill in, as real HTML from your design system. Every change is a new version, never a lost one.

Agent

Point at it. It's fixed.

Pin a comment on any part of a board. Your agent reads it and draws the next version.
