Real interactions
Inputs, validation, state and navigation rather than connected rectangles.
For designers
Design real products, not idealized screens.
Prototype behavior, unhappy paths, permissions and onboarding in the product itself—then hand over the implementation, not an interpretation.
Behavior is the design
The edge cases belong in the prototype.
Empty data, loading, errors and restricted actions shape the experience. Master lets you design them alongside the polished path.
What you can ship
Built around the work, not a generic template.
Unhappy paths
Design errors, retries, partial setup and empty dashboards deliberately.
Role behavior
Show what changes for admins, members, customers and guests.
Shared visual systems
Use semantic tokens, reusable components and controlled variants.
Responsive outcomes
Evaluate the actual experience on phone, tablet and desktop.
Implementation handoff
Give engineering a functioning repository they can inspect and extend.
From brief to use
One continuous path to a working product.
01
Bring the context
Start with a sentence, document, screenshot or the data your team already uses.
02
Review the plan
Master maps the screens, data and open decisions before changing the project.
03
Use the real thing
Test working flows, roles and edge cases in a live preview instead of reviewing static screens.
04
Publish and improve
Launch when ready, learn from real use and continue in the same project.
Start with this
Useful from the first week.
01
Prototype onboarding
Test sequencing, defaults and permissions before implementation.
02
Explore system states
Build the failure modes and sparse states that static files hide.
03
Prove the system
Apply tokens and components across real screens and responsive sizes.
Frequently asked.
Can it match our design system?+
Yes. Master can build with your tokens, components, fonts and brand rules.
Can I edit visually?+
Yes. Select elements in the preview and refine presentation while changes remain in code.
Does it replace Figma?+
Not necessarily. Use Figma for exploration and Master when behavior and implementation matter.
Can developers continue the work?+
Yes. The output is standard React code in a normal repository.
Design the behavior people will actually use.
Start free, keep the code, and publish when you are ready.
