01Compile+
TypeScript in. Possibility out.
A native Rust compiler transforms TypeScript and JSX. Route-level CSS ships the styles each page actually uses.
TypeScript / JSX → tsc-rs
THE RUST APPLICATION ENGINE
Less stack.
More possibility.
From your first line of code to a running application. bext brings compilation, execution, and delivery together in one powerful Rust engine.

FIG. 01 / BEXT ENGINE
One binary. Every layer.
YOUR CODE. YOUR TOOLS. ONE ENGINE.
Native TSX with PRISM. Adapters for your existing stack.
01 / A SMALLER STACK. A BIGGER IDEA.
You build the app. We brought the engine.
Great ideas deserve a shorter path to production. Give your code a compiler, a runtime, and a delivery layer that already work together.
02Execute+
A place for every idea to run.
Warm V8 isolates execute your loaders and components. PRISM turns server-first TSX into HTML, with streaming and caching built in.
V8 isolates → streaming SSR
03Deliver+
The last mile, already built.
Routing, automatic TLS, compression, and ISR caching live in the same engine. Less infrastructure to stitch together.

02 / FOLLOW THE CODE
One continuous flow.
Follow a PRISM page from source to response. Select a stage to look inside.
01 / 04
It starts with familiar code.
File-based routes. TypeScript. JSX. Build a page in PRISM with the syntax you already know.
Try real code in the playgroundexport default function Home() {
return (
<main>
<h1>Hello, possibility.</h1>
<p>Built with bext.</p>
</main>
);
}bext / PRISM TypeScript → HTML
02 / 04
Let the compiler do the work.
tsc-rs transforms TypeScript and JSX. PRISM folds static markup at compile time and generates the CSS your route needs.

Keep execution close to the metal.
The Rust server dispatches the route into a warm V8 isolate. Loaders resolve data and the page renders on the server.

HTML reaches the browser with route-level CSS. Configure caching, compression, and automatic TLS in the same engine.
