Which framework offers the best memory usage and rendering performance—React, Vue, or Angular?

This examines real-world benchmarks to compare the frameworks’ memory efficiency and how quickly they render UI updates.

Performance comparisons from 2025 show: • Vue leads in memory efficiency and rendering due to its fine-grained reactivity system. • React performs nearly as well, with optimized virtual DOM and concurrent rendering improvements. • Angular requires more memory and blocking time, but recent updates like AOT, Ivy, and Signals help close the gap.
