A web framework written in Rust for TypeScript.

---

Kito is the web framework written in Rust and exposed in an end-to-end type-safe TypeScript API. Inspired by tRPC, Elysia, and ExpressJS, Kito aims to unify the ease and convenience of TypeScript with the performance and speed of Rust.

Underneath it uses Actix, one of today's fastest web frameworks. Enjoy serving millions of requests concurrently without breaking away from familiar syntax. You don't need to touch Rust or overcomplicate things to create truly efficient services. Here's a basic, typical example of a Kito application:

import { kito } from "kito"

const app = kito()

app.get("/", (req, res) => {
  res.send("Hello world!")
})

app.listen(3000)

Nothing else! It's that easy. Kito is initially available in Deno and Bun, due to technical implications, although support for NodeJS is being worked on.

All Kito documentation can be found on the official website. One of our biggest efforts is to always provide detailed and up-to-date material, so it's rare to see something undocumented.

Kito's performance is clearly exceptional. After all, what is being measured is not a TypeScript framework, but a Rust one. It is arguably the fastest in the ecosystem without a doubt, as the benchmarks show.
