What is FancyBorderRadius?
Every frontend developer knows CSS border-radius. Far fewer know that the property accepts eight separate values, producing organic, almost biological shapes that go well beyond rounded corners. FancyBorderRadius is a free web tool by 9elements that makes exactly this range visually accessible. In the browser, you adjust values with sliders or input fields, see the shape immediately as a rendered preview, and copy the finished CSS code to the clipboard with one click. No account, no installation, no expiry date.
Core features
- Real-time preview: Changes to the eight border-radius values appear instantly as a rendered shape, with no page reload or delay.
- CSS code generation: The tool outputs a fully formatted, copy-ready CSS expression that can be dropped directly into stylesheets or design tokens.
- Asymmetric control: All four corners can be controlled independently in both the horizontal and vertical directions, enabling asymmetric, organic outlines.
- Open source without restrictions: The repository is publicly available on GitHub, the service is free, and no registration is required.
Who is FancyBorderRadius for?
Frontend developers who want to create organic shapes for hero sections, cards or buttons save themselves the trial-and-error phase in a code editor. Anyone who has manually experimented with complex border-radius values knows how tedious that becomes with eight parameters. UI designers without a deep CSS background can explore shapes and hand the output directly to developers. Anyone who needs to save projects or export shapes (for a shared design system, for example) will have to look elsewhere. FancyBorderRadius offers neither a save function nor an export option.
Context & alternatives
The tool belongs to the category of single-purpose CSS generators that make one specific aspect of a stylesheet manageable through visual interaction. Similar tools exist for box-shadow, gradient and clip-path, and they follow the same principle: visual input, code output, no overhead. FancyBorderRadius is limited to exactly one property. Those looking for a broader CSS toolbox can turn to more comprehensive generators such as Neumorphism.io or CSS-Portal. For prototyping organic shapes specifically via border-radius, though, this is the specialised tool that none of the all-rounders match in depth.
