Juice Curve Lab — Game Animation Easing Designer

Tune game-feel motion without guessing

Juice Curve Lab is a focused offline motion-curve designer. Adjust cubic-bezier control points and duration, preview the feel instantly, and export a clear handoff for web or game-engine work.

WHAT IT DOES

• Live motion preview with replay and loop modes

• Editable control points and 100–2000 ms duration

• Five useful presets, including back-out and springy motion

• Copy-ready CSS plus JSON, Godot, and Unity reference exports

INCLUDED

• Ready-to-run single-file browser app

• Readable HTML, CSS, and JavaScript source

• Quick-start README and commercial-output license

The Godot and Unity files are intentionally readable reference snippets; engine-specific motion should still be tuned in context.

Privacy: runs locally with no account, analytics, uploads, or network requests.

Compatibility: current desktop browsers on Windows, macOS, or Linux.
