Visually build CSS loading spinners and animations. Customize every detail and get production-ready code.
A CSS Animation / Loader Generator is a visual tool that lets you create custom loading spinners, pulse animations, bounce effects, and other CSS loader components without writing code by hand. Instead of hunting for the perfect loader on CodePen and manually tweaking values, you can adjust colors, sizes, speed, and easing visually. The tool generates clean, production-ready CSS code that you can copy and paste directly into your project. Whether you need a simple spinner for an API call or a complex animated progress bar, this tool helps you build it in seconds.
Eight loader types: Spinner (rotating circle border), Pulse (pulsing ring), Bounce (bouncing dots), Wave (wavy bars), Ring (overlapping rings), Dots (jumping dots), Hourglass (flipping timer), and Progress Bar (animated fill bar).
Yes. You can set animation duration from 0.5s to 2s and choose from 7 easing functions including linear, ease, ease-in, ease-out, ease-in-out, and custom cubic-bezier curves like bounce and snap.
Yes. The generated CSS uses standard @keyframes animations with vendor prefixes handled automatically. The code is minimal, clean, and works in all modern browsers. Just copy, paste, and the loader works.
A spinner is a single rotating circle with a gradient border (one side transparent). A ring uses multiple overlapping ring elements that scale and fade at different times, creating a ripple effect.
