Rullst - 📜🦀🌐🤖🚀

"Rust for those who want to build, not suffer."

Read this in Português (Brasil).

Rullst (Rust + Fullstack) is an opinionated, developer-first full-stack web framework for Rust, obsessively designed for Emotional Productivity.

It was created to solve the biggest problem in the Rust web ecosystem: the high barrier of entry that turns web programming into a PhD research on compiler design. We believe you should spend your energy building your business, not fighting borrow checkers and manual routing setups.

💡 The Rullst Manifesto

"Most Rust frameworks treat the web developer like a compiler engineer. Rullst treats the developer like someone who wants to build awesome products at lightning speed."

In the current ecosystem, to write a simple CRUD, you are forced to glue dozens of crates together, manually map nested routing trees, write verbose ORMs requiring multiple structs, and continuously clone variables inside dynamic HTML templates just to satisfy the borrow checker.

Rullst redefines this experience. We offer an integrated, cohesive developer experience that brings the sweetness and iteration speed of Laravel and Next.js together with the Formula 1 performance and military-grade safety of Rust, Axum, and Hyper:

• No More Frankenstein setups: A single cohesive framework managing your server (Axum), your database (rust-eloquent), and your HTML rendering.
• No More Borrow Checker fights in UI: Our compile-time JSX-like html! macro processes pure elements on the server (SSR). It generates optimized string-builders directly at compile time. It's blazing fast, safe, and SEO-friendly by default.
• First-Class Active Record ORM: Native integration with your rust-eloquent package. Interacting with databases is as intuitive as user.save().
• AI-Native Engineering & AI-Friendly: Designed from the ground up for modern pair-programming. Strict type-safety, zero dynamic runtime magic, automatic .ai-rules scaffolding, and structured schemas prevent AI agent hallucinations and allow instant compiler self-correction.

🏆 Everything You Need, Built-In (v1.0.1)

Rullst ships with 7 completed milestones covering every layer of modern web development:

🎨 The "Hello World" That Conquers at First Sight

This is a complete, fully operational web server with type-safe routing, compile-time HTML rendering, and automatic XSS escaping. It is exactly 20 lines of code:

use rullst::{html, routes, Server, Router, response::{Html, IntoResponse}};

async fn hello() -> impl IntoResponse {
    Html(html! {
        <main style="display: grid; place-items: center; height: 100vh; background: #090d16; color: #fff; font-family: system-ui;">
            <div style="text-align: center;">
                <h1 style="font-size: 4rem; margin: 0; background: linear-gradient(135deg, #00f2fe, #4facfe); -webkit-background-clip: text; -webkit-text-fill-color: transparent;">
                    "Hello, World!"
                </h1>
                <p style="color: #64748b; font-size: 1.25rem; margin-top: 1rem;">
                    "Written in Rust. Rendered in microseconds. Safe by default."
                </p>
            </div>
        </main>
    })
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    Server::new(routes![get("/" => hello)])
        .run(3000)
        .await?;
    Ok(())
}

⚡ Get Started in 10 Seconds

Scaffold a fully operational application with our interactive CLI wizard!

# 1. Run the interactive CLI scaffolding tool

cargo rullst new


# The wizard will prompt you:

# 🚀 App name? -> my-app

# 🏗️ What would you like to build? -> SaaS App / REST API

# 🗄️ Select a DB Provider -> Sqlite / Postgres / MySQL


# 2. Enter the project folder

cd my-app


# 3. Start your high-performance full-stack app immediately!

cargo run


# 🔥 Or enable instant Hot Reloading (no server restart!):

HOT_RELOAD=1 cargo run

🛠️ The Full-Stack Active Record Experience

When your application grows, Rullst scales with you using Active Record:

use rullst::{html, routes, Server, Router, response::{Html, IntoResponse}};
use rust_eloquent::{Eloquent, EloquentModel, sqlx::{self, FromRow}};

#[derive(Debug, Clone, FromRow, rust_eloquent::Eloquent)]
#[eloquent(table = "users")]
pub struct User {
    pub id: i32,
    pub name: String,
}

async fn home() -> impl IntoResponse {
    // Elegant, type-safe data fetching
    let users = User::all().await.unwrap();

    Html(html! {
        <div style="background: #0f172a; color: #fff; padding: 5rem; text-align: center; font-family: sans-serif;">
            <h1>"Total Active Users: " {users.len()}</h1>
        </div>
    })
}

// 1. Declare the artisan macro here to intercept CLI arguments for migrations
rullst::artisan!();

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // 2. The artisan! macro automatically intercepts `db:*` commands and exits early.
    // If it's a normal run, it continues server execution here.

    let router = routes![
        get("/" => home),
    ];

    Server::new(router)
        .run(3000)
        .await?;

    Ok(())
}

🗄️ Database Migrations (Artisan CLI)

Rullst includes an embedded, high-performance migration runner. You don't need external binaries. The framework ships with a CLI tool that parses pure Rust closures to construct your schema safely.

# Scaffold a new migration using pure Rust DSL

cargo rullst make:migration create_users_table


# Run all pending migrations against your database

cargo rullst db:migrate


# Rollback the last batch of migrations

cargo rullst db:rollback

Under the hood, these commands are intercepted by the rullst::artisan!() macro, guaranteeing the server never starts when you only want to migrate your database.

🛡️ Self-Healing Upgrades

Afraid of breaking changes when upgrading the framework? Don't be. Rullst was built with a "Self-Healing Upgrades" philosophy.

When a new version of Rullst introduces API changes, we never break your code immediately. Instead, we use #[deprecated] warnings. You can update your entire application automatically using our CLI:

cargo rullst upgrade

This command will safely update the Rullst dependency and use Rust's powerful cargo fix refactoring tools to automatically rewrite your code to match the new API signatures. Stress-free upgrades, forever.

🔥 Hot Reloading (Zero Downtime Dev Loop)

Rullst supports Hot Reloading via Dynamic Linking — change your routes, handlers, and templates, and see the changes reflected instantly without restarting the server or losing connections:

# Start your app in hot-reload mode

HOT_RELOAD=1 cargo run


# ⚡ Edit any handler in src/ → Rullst detects the change

# 🔄 Background recompilation of the cdylib

# 🚀 Router hot-swapped atomically — zero downtime!

Under the hood, Rullst compiles your routes as a dynamic library (cdylib), loads it via libloading, and uses a notify file-watcher to detect changes and trigger background rebuilds. The router is swapped atomically via Arc<RwLock<Router>> — the HTTP server never restarts and TCP connections are never dropped.

🎯 Architecture under the hood (v1.0.1)

Rullst is structured as a modular monorepo Cargo Workspace to optimize compile times:

1. rullst (Core Crate): Wraps and configures Axum, handles life-cycle DB injection, and exposes response types. Ships with production utilities (Queue, Cache, Scheduler), enterprise features (Validation, Mailer, Storage, WebSockets, Horizon), AI-Native core (rullst::ai), Rullst Live (server-driven UI), Wasm Islands, and Hot Reloading via dynamic linking.
2. rullst-macros (Compiler-Engine): Procedural JSX-like compiler that outputs safe memory-buffer string extensions at compile time.
3. cargo-rullst (CLI Scaffold): Scaffolds clean, isolated local-linked workspaces that compile out-of-the-box.
