⚡ Dartalyst: A New Full-Stack SSR Framework That Just Hit 30,937 Requests Per Second

Shaquel Kothari — Fri, 28 Nov 2025 04:13:39 +0000

Over the past year, I’ve been building a new full-stack web framework from the ground up — one that doesn’t rely on Node.js, Webpack, or the typical JavaScript ecosystem. Instead, it’s built on two compiled languages working together:

Dart (NevaehUI) for the frontend
Crystal (KothariAPI) for the backend

The combined framework is called Dartalyst, and based on internal benchmarks, it now ranks among the fastest SSR frameworks currently measured.

This post breaks down the numbers, the comparisons, and why this architecture works — with public testing opening in 3 weeks.

🚀 SSR Benchmark Results

Dartalyst was tested across four workloads:

Test	Throughput
Simple SSR	30,937 req/s
Concurrent SSR	25,897 req/s
Complex Components	7,029 req/s
Data Fetching (SSR)	6,887 req/s

All tests included:

HTML generation
Component rendering
State serialization
Hydration markers
Real routing logic

No caching.
No pre-rendering.

Just actual SSR.

📊 How Dartalyst Compares to Established SSR Frameworks

Below is a comparison using publicly available SSR benchmark ranges (not raw HTTP benchmarks).

🥇 Top-Tier SSR (20,000+ req/s)

Framework	Approx. SSR Throughput
Dartalyst	30,937 req/s
Bun SSR	15,000–30,000
Qwik	10,000–25,000

Dartalyst lands at the top of this tier.

🥈 High-Performance SSR (5,000–15,000 req/s)

Framework	Approx. Throughput
SolidStart	8,000–15,000
SvelteKit	7,000–12,000
Preact SSR	~2,052

🥉 Mainstream SSR (1,000–5,000 req/s)

Framework	Approx. Throughput
Next.js	2,000–7,000 (React 19 SSR ~572)
Remix	3,000–8,000
Nuxt (Vue 3)	2,000–6,000
Angular SSR	3,000–6,000
Astro	2,000–5,000

⛔ Low-End SSR (< 1,000 req/s)

Framework	Approx. Throughput
Laravel SSR	1,000–3,000
Rails SSR	500–2,000
React SSR (Node)	~366
React SSR (Bun)	~650
React SSR (Deno)	~601

🎯 Final Ranking (Technical, Not Marketing)

Based strictly on available data:

Dartalyst is currently in the top 3 fastest SSR frameworks measured — competitive with Qwik and Bun SSR, and faster than most mainstream SSR frameworks (Next.js, Nuxt, Remix, SvelteKit, Angular, etc).

This is actual SSR performance, not HTTP echo servers.

🔧 Why Dartalyst Performs So Well

Because the entire stack is compiled, not interpreted.

NevaehUI (Dart)

Compiler-based rendering
No virtual DOM
Tailwind-style utilities
Hydration only where needed

KothariAPI (Crystal)

Native binary backend
Rails-inspired routing + models
Low-latency HTTP stack

Dartalyst (Full-Stack Layer)

Shared routing
Full SSR pipeline
Unified CLI
No Node.js
No Webpack/Vite
Minimal runtime overhead

The result: very high throughput under load.

⏳ Public Testing Opens in 3 Weeks

The first public release (v0.1.0) will be available between December 15–22, 2024.

It will include:

Full SSR
Hydration
Template rendering
Project scaffolding
NevaehUI components
Crystal backend
Basic documentation
Example apps

You’ll be able to benchmark it yourself.

🔮 What’s Next

v1.0.0 release (Jan 2025)
Streaming SSR
More templates
Security hardening
Documentation site
Community packages
Official benchmark suite

✔️ Final Thoughts

Most web frameworks today are slowed down by:

virtual DOMs
JavaScript hydration
layered toolchains
runtime overhead

Dartalyst shows what’s possible when you remove all of that and build a full-stack SSR system from two compiled languages.

If you want to follow the release or run benchmarks yourself, keep an eye out — early access drops in 3 weeks.
