- Collaborate and share projects with colleagues and customers
- Import Figma variables and generate usable HTML
- Generate and refine themes with AI conversational prompts
What ThemeBuilder Can Do For You
Designing and styling your app is a small part of the web development journey, but can cause slowdowns and even interpersonal friction. Unless you’ve got the right tools for it. Enter: ThemeBuilder.
Your Command Center for UI Customization
Do you need to tweak color palettes, adjust layouts, or refine padding and typography? ThemeBuilder gives you full mastery over every styling element. The result is a visually cohesive app that’s precisely on-brand.
Do You Work With Others?
All team members involved in styling and design, whether developers or designers, can share projects and collaborate.
- Enjoy the intuitive visual interface for styling web UI
- Build on existing work by importing your own CSS
- Iterate freely with version control
Enhanced Designer-Developer Collaboration
No more playing “find the difference” and infinite feedback loops. The ThemeBuilder Figma plugin exports your design files and converts Figma variables to SASS/CSS variables. Link them to your UI components, and future design updates will automatically sync.
Are You Using the Telerik and Kendo UI Component Libraries?
Take advantage of advanced component and theme integration, plus matching Figma UI kits that give designers and developers a common language.
Dynamic AI Theme Generation
With prompt-to-theme chat, you can create a theme draft in seconds, then refine it through natural, conversational feedback. Adjust colors, spacing, typography, and accessibility in plain language - and see instant updates.
Need Fast Iteration with Full Control?
Speed up theme generation with AI, while staying in charge of every detail.
- Generate a complete theme draft instantly
- Refine with step-by-step adjustments in plain language
- Preview and apply changes directly in your project
Figma-to-HTML Conversion That Works
Automate your design-to-development workflow by generating usable HTML from Figma. The ThemeBuilder design-to-HTML plugin recognizes and lists all Figma components. Connect them to your code and get friendly HTML that reuses your existing components.
Are You Working Without a Designer?
Whether you use pre-built page templates or work with designs provided by an agency, you can still use ThemeBuilder to take any Figma design and kickstart your development process.
