Nectar — The Web Without JavaScript

Nectar

The web needs JavaScriptdoesn't. Nectar compiles to WebAssembly. One language, one binary, zero dependencies. Your entire app — logic, state, rendering — runs in WASM. JavaScript is reduced to a 10 KB syscall layer. Note: The Svelte demo may time out on first load with 10K products. Try refreshing if it appears blank.

Write less. Ship faster. // package.json: 47 dependencies // node_modules: 1,247 packages import React, { useState } from 'react'; import ReactDOM from 'react-dom';

function Counter() { const [count, setCount] = useState(0); return ( <div> <p>{count}</p> <button onClick={() => setCount(c => c + 1)}> + </button> </div> ); } // No package.json. No node_modules. // One file. Compiles to WASM.

component Counter() { let mut count: i32 = 0;

fn increment(&mut self) { self.count = self.count + 1; }

render { <div> <p>{format("{}", self.count)}</p> <button on:click={self.increment}>"+"</button> </div> } }

Built different. ⚙ Single Binary Compiler One Rust binary handles everything: compile, format, lint, test, dev server, LSP, package management, SSR. No toolchain to configure. ⚡ Fine-Grained Signals O(1) updates per binding. No virtual DOM, no diffing, no reconciliation. When a signal changes, only the exact DOM node updates. 🔒 Compile-Time Safety Rust-inspired borrow checker, type system, and exhaustive pattern matching. Catch bugs before they ship — not in production.

📦 Zero Dependencies No npm, no node_modules, no webpack, no bundler. Your app compiles to a .wasm binary and a 3 KB runtime. That's it. 🌐 Built-In Keywords component, store, router, page, form, auth, payment, upload, db, cache, agent — common web patterns are language primitives, not libraries. 🚀 SSR + Edge Deploy The same WASM binary runs on the server via wasmtime. Built-in SSR, hydration, and deployment to 29 Cloud Run regions.

How Nectar works Your .nectar source compiles to WebAssembly. The browser loads the .wasm and a 10 KB syscall layer. Everything else is WASM.

See it running. 10,000 products. Canvas rendering engine. Reactive signals. All running in WebAssembly. Side-by-side with Svelte 5.
