The Honest Conclusion on Throughput

Rullst is built on top of Axum and Tokio. As the data clearly shows, adding a massive suite of developer tools (dynamic routing macros, security middlewares, resilience shields, database ORMs) introduces a measurable "Framework Tax."

Under raw load, Rullst caps out at around ~13,000 Reqs/s for Plaintext and ~10,800 Reqs/s for JSON. While it does not beat the raw micro-framework speeds of pure Axum, Actix-web, or Fiber, it still delivers massive performance compared to mainstream industry standards.

How Rullst Compares (JSON)

~3x faster than Spring Boot
~7x faster than NestJS
~15x faster than Django
~20x faster than Laravel Octane
~57x faster than Next.js
~172x faster than Ruby on Rails

*Note: Laravel Octane was benchmarked with Swoole. Ruby on Rails struggled heavily in JSON serialization under 125 concurrent connections, leading to deadlocks/timeouts similar to PHP workers under heavy load.

Final Verdict

If your goal is to build an API that does absolutely nothing but return a string 120,000 times per second, use Axum, Actix-web, or Fiber.

If your goal is to build a full-fledged, secure, and maintainable SaaS product with databases, queues, AI integrations, Hot-Reloading, and an Auto-CMS in a matter of days—while still comfortably supporting over 10,000 requests per second—Rullst is your framework.

Performance vs. DX Scorecard

Framework	Language	Performance	DX	Notes
Axum / Actix	Rust	⭐⭐⭐⭐⭐	⭐⭐	Absolute maximum speed, but you must build everything from scratch.
Fiber / Gin	Go	⭐⭐⭐⭐⭐	⭐⭐⭐	Very fast and simple, but lacks the massive built-in features of a true fullstack framework.
Rullst	Rust	⭐⭐⭐⭐	⭐⭐⭐⭐⭐	High-level fullstack APIs, ORM, Auth, and Hot-Reloading with Rust's memory safety.
Loco	Rust	⭐⭐⭐⭐⭐	⭐⭐⭐⭐	Rails-like experience in Rust, excellent speed but slightly steeper learning curve.
Leptos	Rust	⭐⭐⭐⭐	⭐⭐⭐⭐	The king of Rust fullstack WASM frontend, but backend API patterns are tied to SSR.
Rocket	Rust	⭐⭐⭐⭐	⭐⭐⭐⭐	Fantastic DX for pure Rust, but less "batteries included" than Rullst or Loco.
Spring Boot	Java	⭐⭐⭐	⭐⭐⭐	Enterprise standard, decent speed, but heavy memory footprint and boilerplate.
Ruby on Rails	Ruby	⭐⭐	⭐⭐⭐⭐⭐	The original "batteries included" framework. Beautiful DX, but scales poorly under high load.
NestJS	JS/TS	⭐⭐	⭐⭐⭐⭐	Beautiful architecture, but heavily bottlenecked by Node.js single thread under load.
Laravel	PHP	⭐	⭐⭐⭐⭐⭐	Incredible ecosystem and DX, but poor raw throughput under high concurrency.
Django	Python	⭐	⭐⭐⭐⭐⭐	Great "batteries included" framework, but heavily bottlenecks under high load.
Next.js	JS/TS	⭐	⭐⭐⭐⭐	Fantastic for frontend SSR, but backend API routes are very slow under load.
Zap	Zig	⭐⭐⭐	⭐	Extremely low-level C-like performance, but almost non-existent ecosystem/DX for web.

Why Rullst? Key Architectural Benefits

While Rullst competes closely in performance with bare-metal Rust frameworks like Axum and Actix-web, it stands out due to its unique architectural choices designed for modern software development and AI collaboration:

🛡️ Enterprise-Grade Security Matrix

Rullst is "Secure by Design", natively shipping with OWASP ZAP DAST scanning, OSSF Scorecards, cargo-fuzz, cargo-mutants, and hardcore mitigations against Timing Attacks, WAF bypasses, and CSRF DoS vectors out-of-the-box.

⚡ Auto-Migrations in Dev Server

Experience unmatched Developer Experience (DX). cargo rullst dev now automatically and silently runs your database migrations before hot-reloading your application, ensuring your schema is always perfectly synced with your code.

🤖 AI-Native & Code-Reasoning Optimization

Rullst is architected to be highly readable and predictable. By avoiding runtime magic, implicit reflection, or dynamic dependency injection, AI coding assistants (like Gemini/Claude) and developers can easily parse, trace, and modify the application without fear of runtime bugs.

🛡️ Compile-Time Guarantees

Rullst prioritizes catching structural bugs, route definition issues, and middleware mismatches at compile time rather than relying on runtime failures or comprehensive test suites.

🔒 Strict Type Safety (No Dynamic Traits)

Rullst avoids heavy usage of dyn Trait in favor of static dispatch and strong typing. This leads to better compiler optimizations (monomorphization), smaller binaries, and robust memory/concurrency safety guarantees.

🗺️ Explicit API Design

There is no hidden state or magical middleware sequencing. Everything (routes, shared state, filters, extensions) is explicitly declared and wired, preventing side effects and making codebase maintainability simple.

⚖️ Balanced DX & Performance

Rullst delivers high throughput and low latencies comparable to microframeworks like Axum, but provides a structured scaffold reminiscent of full-stack frameworks (like Loco or NestJS) without sacrificing performance.

🔄 Autonomous Upgrades

Never fear breaking changes again. cargo rullst upgrade performs AST-based codemods in the background to automatically update your syntax when the framework evolves.

🌍 Edge Fusion & Replication

Compile to WebAssembly for Cloudflare Workers globally, backed by built-in Turso/libsql replication for 1ms database read latency worldwide.

📱 Omni-Frontend Wasm

Write frontend interactive components strictly in Rust (#[client_component]). They compile to lightweight Wasm, eliminating the need to write JavaScript for SPAs or Desktop apps.

Documentation

Getting started is simple. Explore Rullst's batteries-included features below or visit our GitHub for the full guide.

Declarative Active Record ORM

Define your models with simple macros. No need for separate schema files or manual SQL queries. Features built-in multitenancy support.

use rullst_orm::Orm;
use rullst::db::FromRow;

#[derive(Debug, Clone, FromRow, Orm)]
#[orm(table = "posts", global_scope = "apply_tenant_scope")]
pub struct Post {
    pub id: i32,
    pub tenant_id: String,
    pub title: String,
    pub body: String,
}

// Global scopes apply automatically to all queries!
impl PostQueryBuilder {
    pub fn apply_tenant_scope(self) -> Self {
        if let Some(tid) = rullst::multitenant::current_tenant_id() {
            self.where_eq("tenant_id", tid)
        } else {
            self
        }
    }
}

Blazing Fast SSR with html!

Write type-safe HTML directly in Rust. It compiles to zero-allocation String concatenation, beating traditional templating engines by 2x-5x.

use rullst::html;

fn render_post_list(posts: &[Post]) -> String {
    if posts.is_empty() {
        html! {
            <div class="empty-state">
                "No posts published yet. Be the first to share a story!"
            </div>
        }
    } else {
        posts.iter().rev().map(|post| {
            html! {
                <div class="post-card">
                    <h3 class="post-title">{&post.title}</h3>
                    <p class="post-body">{&post.body}</p>
                </div>
            }
        }).collect()
    }
}

Intuitive Routing & Middleware

Declare your routes elegantly. Wrap your entire application with tenant-aware context, auth layers, and more using an Axum-compatible foundation.

use rullst::routes;

#[unsafe(no_mangle)]
pub extern "C" fn rullst_router_init() -> *mut rullst::Router {
    // Configure multitenancy by HTTP header
    let config = rullst::TenantConfig::new(rullst::TenantStrategy::Header)
        .with_header_name("X-Tenant-ID");

    // Define routes
    let router = routes![
        get("/" => index_handler),
        post("/posts" => store_post_handler),
        get("/api/health" => health_check),
    ]
    .layer(rullst::tenant_layer(config));

    Box::into_raw(Box::new(router))
}

WebSockets & Live Components

Build reactive components (like Phoenix LiveView) directly in Rust, powered by WebSockets. State stays on the server, UI updates seamlessly.

pub async fn live_demo() -> impl IntoResponse {
    let component = rullst::live::Live::mount::<CounterComponent>("/_live").await;
    
    Html(html! {
        <html lang="en">
        <head>
            <script src="https://unpkg.com/htmx.org@1.9.11"></script>
            <script src="https://unpkg.com/htmx.org@1.9.11/dist/ext/ws.js"></script>
        </head>
        <body>
            { rullst::html::RawHtml(component) }
        </body>
        </html>
    })
}

pub async fn live_ws(ws: axum::extract::ws::WebSocketUpgrade) -> impl IntoResponse {
    rullst::live::live_ws_handler::<CounterComponent>(ws).await
}
