JavaScript Framework Bundle Size Comparison 2026

Methodology
This dataset evaluates the core packages of major JavaScript frontend frameworks. The intent is to provide a snapshot of the base cost of adoption.
Sources: Minified and gzipped sizes are sourced from Bundlephobia's API. Download numbers are derived from npm's API for the previous 7 days. GitHub stats are fetched directly from the official repositories.
Null values: Due to API rate limits or processing failures on external services (like Bundlephobia failing to build a package), some data points may be absent. We strictly adhere to a "null over fake" policy—if we cannot reliably fetch the data, we display a null value rather than estimating.
Frequently Asked Questions
Which JavaScript framework has the smallest bundle size in 2026?
Based on our analysis, React has the smallest minified core bundle at 7.42 KB.
How big is React vs Vue?
React and Vue have significantly different core architectures. Vue includes more reactivity primitives out of the box, whereas React relies on a separate DOM renderer package. Check the data table above for the exact measurements.
Are newer frameworks like Solid or Svelte actually smaller?
Yes, compile-time frameworks like Svelte and Solid typically produce much smaller initial core bundles because they do not ship a heavy virtual DOM runtime to the browser, instead compiling components to precise DOM operations.
Does bundle size still matter in 2026?
Yes. While average network bandwidth has improved, JavaScript parsing, compilation, and execution time on mid-range mobile devices remains a significant bottleneck for web performance and Time to Interactive (TTI).
How is this framework size data collected?
We crawl live data from Bundlephobia for minified and gzipped core sizes, the npm registry for weekly download metrics, and GitHub for repository stars and language data. All data is embedded directly into this page.
