A simple, incredibly fast Javascript runtime for the AI era.
Sofuu is built natively in C to strip away the bulk of standard web runtimes. Whether you are building intelligent local AI agents or deploying quick microservices to your devices, Sofuu just works flawlessly on local hardware.
Why developers love Sofuu
Smart Integrations
Our built-in tools instantly connect to your local or cloud LLMs. Streaming is handled automatically right out of the box.
100% Private
Your context and state stay exactly where they belong: on your machine. Everything executes locally with zero unprompted telemetry.
Built-in Networking
Forget setting up heavy web frameworks. Sofuu ships with a native, ultra-fast HTTP server built straight into the core engine.
Lightweight & Embeddable
Because it's so incredibly small and fast, Sofuu is the perfect drop-in scripting environment for your next hardware project.
How it works under the hood
Sofuu isn't just a wrapper—it's a fundamental rebuild of the JavaScript experience, perfectly tailored for the speed that AI developers need today.
01. Hardware SIMD Math
We connected JavaScript directly to your CPU's hardware vector registers. This means things like cosine similarity and array math happen almost instantly without slowing down your app.
02. Background LLM Polling
Long network requests from AI models shouldn't crash your server. Sofuu handles heavy data streams entirely in the background, keeping your main app incredibly snappy.
03. Native Web Server
By binding an asynchronous HTTP multiplexer directly over raw OS sockets, you get a clean, functional web server capable of handling massive local burst traffic beautifully.
04. Edge & Embedded Ready
With zero bulk Node modules to manage and lightning-fast boot times, Sofuu is the perfect lightweight logic layer for headless infrastructure and edge hardware.
Fast, simple, and reliable.
We built Sofuu natively in C to bypass the heavy overhead of standard runtimes. Our lean approach to memory means you get peak performance instantly.
| Platform | Execution Pathway | Average Latency | Cost |
|---|---|---|---|
| Sofuu (Local) | SIMD + C-Threads | 12ms | $0.00 |
| Standard Node.js | V8 + JSON Deserialization | ~180ms | Variable |
| Cloud AI APIs | Remote Servers | ~450ms+ | Pay-per-token |
Note: Speeds may vary wildly depending on your local hardware (e.g., Apple Silicon vs. older processors). Always test on your target devices.
