A performance budget sets concrete limits for your website. Recommended budget: total page weight under 500KB (including images), JavaScript under 200KB, first contentful paint under 1.5s, largest contentful paint under 2.5s, time to interactive under 3.5s, cumulative layout shift under 0.1. Toolular hits all these targets by using static HTML, minimal JavaScript, and optimized fonts. Monitor with Lighthouse CI in your build pipeline — fail the build if budget is exceeded.
