Real design, from any starting point to your codebase.
DesignEx is a design partner that works where you work. Start from your codebase, your Figma, or an image you love. It runs on the coding agent you already pay for, then hands off real pages your team can build immediately.
Redesign our checkout. Start from the repo, keep our design system, make it feel effortless.
Start from anything
1.0 · Starting points
Point it at what you already have. A codebase, a Figma file, a screenshot you love, a DESIGN.md, or a catalog starter. DesignEx reads your colors, type, and components first, so the very first design already looks like yours.
No blank canvasRuns on your subscription
2.0 · Your harness
Bring the coding agent you already use. DesignEx runs on your own Claude Code, Codex, Cursor, or OpenCode, so the subscription you already have does the work. Connect it once and start designing.
Bring your own harnessBuild when you’re ready
3.0 · Handoff
Handoff is one step, whenever you choose. The chosen design lands directly in your source codebase: real pages, a build plan, and the reasoning behind every decision. Implementation starts from the real thing, so nothing drifts.
No translation lossA deep bench of skills
Craft that compounds. A massive library of design-engineering skills, from chart form to iOS glass to honest copy, loads exactly when the work calls for it. Integrations bring your references and files into the same conversation.

Tap to open
Your studio, in your pocket. Curate inspiration, test real prototypes full screen, and keep the conversation going from your phone. Everything syncs with your Mac, for you and for your agents.
Always in syncNot another coding agent
Ask for a screen and you get one attempt, written straight into code.
Design decisions happen silently, inside a diff.
Taste is whatever the model woke up with.
Iterating means burning runs on layouts you will throw away.
Explore looks first. Nothing touches the codebase until you choose.
Decide with your eyes. Real, clickable pages built on your design system.
Taste comes from you. Your saved inspiration shapes every direction.
Hand off certainty. A frozen design, a build plan, and every decision explained.
Your coding agent is still the builder. DesignEx is the part that decides what to build, and the handoff is written for it.
Real pages to react to, no code required. Your judgment stays in charge.
Output born on your system and inspectable to the element, ready to ship.
Fewer wasted runs. Design converges before code exists, so the first build is the right one.
Mockups show you a picture of the product. DesignEx hands you the next draft.
DesignEx is a research preview. By default it sends anonymous usage data — counts and timings, never your designs, prompts, or files — so we can see what’s working and make it better. You can turn that off in Settings at any time. Read the privacy notice.
