Why Choose Fixie?
cubic-bezier.com is a classic tool that's been serving the web development community for years. Created by CSS expert Lea Verou, it's clean, focused, and does one thing extremely well: letting you design custom cubic-bezier timing functions.

The tool is fast, ad-free, and respected across the industry.
Fixie's CSS Easing Function Visualizer builds on the same core concept with a few additions. The most notable is the ability to compare multiple easing curves simultaneously with synchronized animation previews — useful when you're deciding between several timing options and want to see them all at once rather than switching between them. Fixie also includes an expanded preset library with Penner Easing Equations beyond the standard CSS keywords. Both tools support custom Bezier curve editing and generate identical CSS output. cubic-bezier.com is a proven, focused tool from a respected CSS expert. Fixie adds comparison features that can speed up decision-making. Both are excellent — choose based on whether you want the classic focused experience or the expanded comparison workflow.
