Serverless framework plugin for blazingly-fast rust functions.

Status

Motivation

💻 Development experience

The goal of this project is to be accessible to beginners and experienced developers. Similar solutions require Docker to run or compile rust which is not practical.

🚀 Faster time-to-market

You can quickly deploy and update serverless applications, reducing the time it takes to bring new features to the market.

⚡️ Blazingly-fast

Experience unparalleled speed with serverless Rust, delivering exceptional performance on serverless infrastructure.

📈 Seamless scalability

Rust offers seamless scalability, effortlessly handling varying workloads, capable of processing millions of requests per minute while maintaining optimal performance.
