I can't seem to tell exactly what they built. They call it a runtime, but they're using NodeJS?

Did they implement a transpiler in Rust?

They also seem to be calling Rust from JS, but not through wasm...

They seem to be doing something with Rust and http, but they're also just using "Pingora"...

Additionally, their homepage is about 20 fps while scrolling on my phone (pixel 4a, brave)

I would honestly love for someone to explain to me wtf is going on.
