Design directly in production code
Handle brings live product design to web apps, with rich visual tools to explore, refine, and land changes directly in code
How it works
Create
Create, explore, and iterate with your existing coding agent and tools.
Refine
Use precision tools to adjust styling and layout, consistent with your design system.
Land
Handle works with your coding agent to realize the changes in your code.
Design with real control again
Work directly on live UI, where every change is real—not interpreted, approximated, or re-created later.
Less translation. More intention.
Stop describing intent through tickets, mocks, or endless re-prompting. Create new UI and adjust layout and styling directly in code.
Eliminate handoff gaps
No more lost context or rework. Changes flow straight into code, reducing handoff loss and iteration cycles.
Higher quality outcomes
Live previews in Handle let you iterate faster and catch edge cases earlier.
