Porffor is a new JavaScript engine that compiles JS to WebAssembly and native binaries, resulting in significantly smaller and faster binaries compared to existing solutions like Node and Bun. Benchmarks show that Porffor outperforms Node and LLRT in cold start times on AWS Lambda, making it a promising alternative despite its early development stage and limited compatibility. The author invites interested parties to explore Porffor for small Lambda applications as it continues to improve.

Porffor is a JavaScript engine that compiles JavaScript code into small, fast binaries using WebAssembly, significantly outperforming traditional runtimes like Node and Bun in speed and efficiency. It has recently been tested on AWS Lambda, showing impressive cold start performance, being approximately 12 times faster than Node and 4 times cheaper. However, Porffor is still in early development and lacks full JavaScript support and I/O capabilities.
