Speed Up the Front End
Measure first, then cut. Bundle, fonts, media, and the jumping layout.
The steps
Your agent works through these in order, and won't break a step it already finished.
UI Performance Budget
Put a number on how heavy and how slow each screen is allowed to get.
Layout Shift Guard
Stop content jumping as a page loads, and catch it when it starts happening again.
Bundle-Aware Component Imports
Stop a single icon or helper from dragging a whole library into the shipped bundle.
Critical CSS Strategy
Get the first screen styled correctly on the first paint, with no flash of raw markup.
Font Loading Strategy
Load the custom fonts without invisible text, broken metrics, or a late reflow.
Font Subsetting
Load only the glyphs a page needs, without breaking the alphabets it did not expect.
Adaptive Media Source Component
Serve each image and video at a size and format the viewer's device can actually use.
Component Render Profiler
Show which components re-render, what triggered it, and which of those actually cost anything.
How to use this collection
One link, several features, one coherent document. Your agent inspects your app once — not once per feature — then implements the set in order, checking after each step that it hasn't broken the last.
Pro users build their own from any features in the library, including their own customized versions.
