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.

| JavaScript Runtime | 10 KB (DOM syscalls only) |
| Virtual DOM | None — command buffer |
| State Management | WASM signals — O(1) |
| Borrow Checker | Compile-time safety |
| node_modules | Zero. Deleted. |
| GC Pauses | None — linear memory |
| XSS Attacks | Impossible — no eval |
| Auth | HttpOnly cookies by default |
