Same Workload.
Fraction of the Cost.
Rust applications use dramatically less compute than Node.js. Pure gives you that efficiency without a rewrite, without new hires, and without changing your code.
The Cloud Cost Problem
Cloud costs scale linearly
More traffic means more containers, bigger instances, higher bills. Node.js applications require significant compute overhead from their runtime, interpreter, and garbage collector.
Rust rewrites are expensive
The traditional path to Rust performance means hiring specialized engineers ($180K+ average), 2-4 months of onboarding, and a 6-18 month rewrite. That's a significant investment before seeing any return.
Optimization has limits
You can optimize your Node.js code, tune your infrastructure, and right-size your containers. But you can't optimize away the fundamental overhead of an interpreted language runtime.
The gap widens at scale
The efficiency difference between Rust and Node.js isn't marginal — published benchmarks show it's measured in multiples. At scale, that multiplier applies directly to your cloud bill.
The Pure Approach
Get Rust efficiency without the rewrite.
No Hiring
No Rust engineers to recruit, onboard, or retain. Your existing team keeps working in JavaScript and TypeScript.
No Rewrite
No 6-18 month rewrite project. No risk of introducing bugs during migration. Your code stays exactly the same.
One API Call
Send your code, get back a native binary. The efficiency gains of Rust, delivered through an API — not a staffing plan.
