Framework Benchmarks

Test each framework for it's performance, particularly common Lighthouse and CWV metrics as applications scale

Important: This is not a measure of "is framework x better than y". There are many tradeoffs to weigh when choosing the best framework for you - such as DX, features, familiarity, ecosystem, documentation, etc. These benchmarks only show a part of the picture.

Goals

The goal for this project are to understand the performance tradeoffs of popular frameworks in real world-ish scenarios. We want to assume non trivial codebases and imperfect code and conditions, so to see how each framework holds up to real world scenarios and scale.

We are intentionally not focused on client side rendering performance, for that please use Stefan Krause's great js-framework-benchmark

Status

This project is in initial development. Do not put too much weight on these current results, there is still much more to do to ensure accuracy, consistency, and fairness.

Contributions are welcome!

How it works

Methodology

We created a basic starting point for each framework in the frameworks/ folder using each framework's suggested starter/cli.

We then create basic example components and use Mitosis to compile them to best-effort idiomatic code for each framework. This will never be perfectly optimized code

We then build and serve each project, and run Lighthouse on each project with puppeteer, including with emulation of slow devices and networks (aka includes CPU and network throttling), and measure:

FCP: First Contentful Paint (lower is better)
LCP: Largest Contentful Paint (lower is better)
TBT: Total Blocking Time (lower is better)
TTI: Time to Interactive (lower is better)
Score: Lighthouse Performance Score (higher is better)
Eager JS Kib: the KiB of JS that is eagerly downloaded and executed from <script> tags for the initial page load. This is the actual size transferred over the network, including compression (lower is better)
Total KiB: the total KiB transferred with the given page, including HTML, CSS, prefetched resources, etc. Also known as the "total byte weight". This is the actual size transferred over the network, including compression (lower is better)

We take the median of multiple runs, and sort the results by TTI, ascending

We are also experimenting with looking at other metrics, such as build times

The Frameworks

Alphabetically:

astro - generated via their official CLI, with Solid for the interactive parts. Source
fresh - generated via their official CLI. Source
gatsby - contributed by the Gatsby team. Source
hydrogen - generated via their official CLI. Source
lit - generated via their official starter. Source
marko - generated via their official CLI. Source
next - generated via their official CLI. Source
nuxt2 - generated via their official CLI. Source
nuxt3 - generated via their official CLI (in beta). Source
qwik - generated with Qwik City (meta framework). Source
react - generated from create-react-app with react-router-dom added for routing. Source
react-ssr-node - Ultra simple Node server to server-side render react. Source
react-ssr-deno - Ultra simple Deno server to server-side render react. Source
react-ssr-bun - Ultra simple Bun server to server-side render react. Source
preact-ssr-node - Ultra simple Node server to server-side render preact. Source
remix - generated from create-remix. Currently excluded from Lighthouse tests by request from the team, from concerns about the code being too non-idiomatic. Source
solid - generated with Solid Start (meta framework). Source
svelte - generated with Svelte Kit (meta framework). Source
vue3 - generated via their official CLI, with routing. Source

Roadmap

Next things we want to add:

More complex examples that more closesly emulate real world sites and apps (e.g. a dashboard for exploring the test run results in interactive tables and graphs)
Test interaction delays - such as initial interaction (like add todo) or navigate to next page
Move test running to be remote, such as in GH actions (Help wanted!)
Benchmark SSR speeds. Also add Bun here.
Benchmark with and without Partytown for 3P scripts (and vs none at all)

Contributions welcome!

Running locally

Prereqs

You will need Node.js >= 16.14.0k Deno installed locally, and Bun installed locally

Setup

After cloning this repo, install dependencies:

npm install

Now you can start running the below scripts:

Install

Use the install script to install dependencies of each framework:

npm run fw-install

Generate

First, we must generate the component code for each framework via Mitosis.

cd apps/components
npm install
npm run build

Build

Use the build script to build all frameworks (be sure to install first as described above):

npm run build

Measure

To measure the weight of each framework (after you ran install and build):

npm run measure
