cubic-bezier.com is a well-known single-purpose tool for designing CSS cubic-bezier timing functions. It offers a clean interface with draggable control points and instant visual feedback. While it's free and doesn't require signup, it focuses exclusively on cubic-bezier curves. Fixie's CSS Easing Function Visualizer provides similar curve editing capabilities plus side-by-side comparison of multiple easing functions and additional animation preview modes.
Frequently Asked Questions
Is cubic-bezier.com or Fixie better for beginners?
Both tools are beginner-friendly with intuitive drag-and-drop interfaces. cubic-bezier.com's singular focus makes it slightly simpler if you're just learning about easing curves. Fixie's side-by-side comparison feature is helpful for understanding how different curves compare, which can accelerate learning. Try both and see which interface feels more intuitive to you.
What's the advantage of comparing multiple easing curves?
Comparing curves side-by-side helps you see subtle differences that are hard to detect when viewing one at a time. This is useful when building design systems that need consistent motion patterns, or when choosing between similar curves like ease-out-quad versus ease-out-cubic. It also helps document animation decisions for team members.
Do both tools support the same CSS output?
Yes. Both generate standard CSS cubic-bezier() functions that work identically in all modern browsers. The curve you create in either tool will produce the same animation timing when used in CSS transitions or keyframe animations.
Can I use custom easing curves in all CSS animations?
Yes. The cubic-bezier() timing function works with CSS transitions, @keyframes animations, and scroll-driven animations. Copy the generated code and use it anywhere you'd use timing functions like 'ease' or 'linear'. Browser support is excellent across all modern browsers.
Which tool is better for production workflows?
Both are production-ready. cubic-bezier.com's simplicity makes it fast for quick curve adjustments. Fixie's comparison features are valuable when maintaining animation libraries or design systems where consistency matters. Choose based on whether you need curve comparison features or prefer a more focused single-curve editor.
