“Nova Apps – FrameSage: Web Animation Performance Analyzer” — what this page in the network covers. Analyze and optimize CSS animations with FrameSage. Detect jank, layout thrashing & paint issues. Get performance scores and optimized code instantly. FrameSage is a professional web animation performance analyzer that empowers developers and designers to create smooth, high-performing CSS animations. Simply paste your @keyframes and animation properties, and FrameSage instantly scans for layout-thrashing and paint-heavy properties that cause jank and poor frame rates.
It delivers a clear performance score, highlights problematic properties with severity badges (jank, warning), and provides a detailed report broken down by keyframe steps. The built-in Optimizer generates an optimized version of your CSS, replacing expensive properties with compositor-friendly alternatives. A live side-by-side preview lets you compare original and optimized animations in real time, with FPS indicators. Save your audits to history for future reference, or load examples to see common pitfalls. The full version stays on the original page, which this listing opens directly.
