One API Call. That's It.
Send your existing JavaScript or TypeScript project. Get back a native Rust binary. Your workflow barely changes — your performance changes dramatically.
Three Steps. Zero Complexity.
Upload Your Code
Call our API with your existing JS/TS project. No changes to your source, no annotations, no configuration files. It works with your code exactly as it is.
Pure Compiles to Rust
Our patent-pending deterministic engine converts your code to Rust behind the scenes. This is a formal compiler — not AI guessing at code. Output is reproducible and verifiable, every time.
Deploy Your Binary
Download a native binary and deploy it anywhere — your cloud, your servers, your containers. It behaves identically to your Node.js app, just faster and leaner.
What Happens Inside
A precise, reproducible compiler — not an AI experiment.
Deterministic, Not AI
Pure is a formal compiler that performs structured, rule-based code transformation. Unlike AI code generators, the output is 100% reproducible — the same input always produces the same output. No hallucination, no guessing, no variability.
100% Output Parity
Your compiled application behaves identically to your Node.js app. We validate against the Bun test suite, the Deno test suite, conformance tests, all 3M+ npm packages, and hundreds of thousands of public GitHub projects. We won't ship until every test passes.
Patent-Pending Technology
Pure is built on 12 patent-pending inventions covering the core transpilation methods — with near-zero prior art in this space. Our patent portfolio covers dynamic-to-static language transpilation broadly.
Your Code Stays Yours
Pure processes your code to produce a binary. You retain full ownership of your source code and the compiled output. Your code is not used to train models or shared with third parties.
Two Ways to Use Pure
npm-compatible package registry
- Switch one URL: npm config set registry https://registry.pure.dev
- Your npm dependencies are served as Rust-compiled binaries
- Keep running in Node.js — your code and workflow stay the same
- Your packages get Rust performance and memory safety
Full application compilation
- Compile your entire application to a standalone native binary
- One API call — no SDKs, no plugins, no build tool changes
- Deploy anywhere: containers, VMs, bare metal — no runtime needed
- Full Rust performance and security for your entire application
Compatibility
Supported Today
JavaScript and TypeScript running on Node.js. Pure handles your existing code, your npm dependencies, and your project structure — no special configuration required.
Coming Next
After general availability, we plan to expand to Python, PHP, Ruby, and more. Our patent portfolio covers dynamic-to-static language transpilation broadly, so the roadmap extends well beyond JavaScript.
