## What it is
A benchmark suite comparing the rendering performance of ~186 JavaScript web frameworks by measuring DOM table operations, memory usage, and startup metrics in Chrome. It publishes official results tables for each Chrome release on a companion website.

## Use cases
- compare rendering performance of javascript frameworks
- find the fastest js framework for dom updates
- measure memory usage of frontend frameworks
- benchmark table rendering speed in the browser
- decide which web framework to pick based on performance
- track framework performance across chrome versions

## When to choose
- you want empirical, reproducible performance data across many JS frameworks
- you are evaluating frontend frameworks for DOM-heavy applications
- you maintain a JS framework and want to measure rendering regressions

## When to avoid
- you need benchmarks of server-side or backend performance
- you want a benchmark of non-JavaScript UI toolkits
- you need a ready-to-use production library rather than a benchmark harness

## Facets
- artifact type: application
- maturity: active
- function: benchmarking, testing, developer-tools
- domain: web-development, frontend, performance, developer-tools
- platform: browser
- tags: js-frameworks, performance-comparison, dom-rendering, frontend-benchmark, lighthouse, nodejs, web
